Torque specifications for control terminals and power terminals are listed in “General Wiring Informa­tion” on page 23.

3.5 Serial Number Label

To determine if your drive is within the warranty time frame, find the bar code label or look in the lower
left of the technical nameplate. The serial number can be broken down as follows:

3.6 Conduit Usage

The Vacon 50X drive in the IP66 enclosure is rated for 70 bar washdown from 15 cm. To keep this rating,
the use of a sealed conduit is required. The use of a Romex-type conduit will not prevent water entry into
the enclosure. If the approved conduit is not used, all warranty claims against water damage will be void.

3.7 Condensation

The washdown process of an Vacon 50X drive may create a temperature and humidity change in and
around the drive. If the unit is mounted in a cool environment and washed down with higher-temperature
water, as the drive cools to room temperature, condensation can form inside the drive, especially around
the display. To prevent this from happening, avoid using sealed connectors around rubbercoated cables
to seal the drive. These do not allow any air transfer and hence create a level of condensation and humid­ity that exceeds the drive’s rating.

This chapter provides information on connecting power and control wiring to the Vacon 50X AC drive.

HAZARDOUS VOLTAGE

• Read and understand this manual in its entirety before in­stalling or operating the Vacon 50X AC drive. Installation,
adjustment, repair, and maintenance of these drives must
be performed by qualified personnel.

• Disconnect all power before servicing the drive. WAIT 5
MINUTES until the DC bus capacitors discharge.

• DO NOT short across DC bus capacitors or touch un­shielded components or terminal strip screw connections

Danger

4.1 General Wiring Information

Pay conscientious attention to ensuring that the installation wiring is installed in conformity with local
standards. Where local codes exceed these requirements, they must be followed.

4.1.1 Wiring Practices

When making power and control connections, observe these precautions:

• Never connect input AC power to the motor output terminals T1/U, T2/V, or T3/W.
Damage to the drive will result.

• Power wiring to the motor must have the maximum possible separation from all
other power wiring. Do not run in the same conduit; this separation reduces the
possibility of coupling electrical noise between circuits.

• Cross conduits at right angles whenever power and control wiring cross.

• Good writing practice also requires separation of control circuit wiring from all
power wiring. Since power delivered from the drive contains high frequencies which
may cause interference with other equipment, do not run control wires in the same
conduit or raceway with power or motor wiring.

4.1.2 Considerations for Power Wiring

Power wiring refers to the line and load connections made to terminals L1/R, L2/S, L3/T, and T1/U, T2/V,
T3/W respectively. Select power wiring as follows:

1. Use only VDE, UL or CUL recognized wire.

2. Wire voltage rating must be a minimum of 300 V for 230 Vac systems and 600 V
(Class 1 wire) for 400 Vac systems.

with voltage present.

• Install all covers before applying power or starting and
stopping the drive.

• The user is responsible for conforming to all applicable
code require-ments with respect to grounding all equip­ment.

• Many parts in this drive, including printed circuit boards,
operate at line voltage. DO NOT TOUCH. Use only electri­cally-insulated tools.

Before servicing the drive:

• Disconnect all power.

• Place a “DO NOT TURN ON” label on the drive disconnect.

• Lock the disconnect in the open position.

Failure to observe these precautions will cause shock or
burn, resulting in severe personal injury or death.

Tel. [phone] • Fax [phone]

connections vacon  24

3. Wire gauge must be selected based on 125% of the continuous input current rating
of the drive. Wire gauge must be selected from wire tables for 75 °C insulation rat­ing, and must be of copper construction. The 230 V 5.5 and 11 kW models, and the
460 V 22 kW models require 90 °C wire to meet UL requirements. See Chapter 2 for
the continuous output ratings for the drive.

4. Grounding must be in accordance with VDE, NEC and CEC. If multiple Vacon 50X
drives are installed near each other, each must be connected to ground. A central
earthing point should be used for interference suppression (e.g. equipotential
bonding strip or centrally at an interference suppression filter). The earthing lines
are routed to the respective terminals radially from this point. Conductor loops of

4.2 Input Line Requirements

4.2.1 Line Voltage

See “Power and Current Ratings” on chapter 2.2 for the allowable fluctuation of AC line voltage for your
particular Vacon 50X model. A supply voltage above or below the limits given in the table will cause the
drive to trip with either an overvoltage or undervoltage fault.

Exercise caution when applying the Vacon 50X AC drive on low-line conditions.

For example, an Vacon 50X 2-series unit will operate properly on a 208 Vac line, but the maximum output
voltage will be limited to 208 Vac. If a motor rated for 230 Vac line voltage is controlled by this drive, higher
motor currents and increased heating will result.

Therefore, ensure that the voltage rating of the motor matches the applied line voltage.

4.2.2 Use of Isolation Transformers and Line Reactors

In nearly all cases, the Vacon 50X drive may be connected directly to a power source. However, in the fol­lowing cases, a properly–sized isolation transformer or line reactor should be utilized to minimize the
risk of drive malfunction or damage:

• When the line capacity exceeds the requirements of the drive (see Section 4.2.3).

• When power factor correction capacitors are used on the drive’s power source.

• When the power source experiences transient power interruptions or voltage
spikes.

• When the power source supplying the drive also supplies large devices (such as DC
drives) that contain controlled rectifiers.

Table 6:Transformer Sizing for the Vacon 50X Drive

4.2.3 Line Capacity

If the source of AC power to the Vacon 50X drive is greater than 10 times the kVA rating shown in Table 6,
an isolation transformer or line reactor is recommended. Consult VACON for assistance in sizing the re­actor.

NOTE: Vacon 50X AC drive devices are suitable for use on a circuit capable of delivering not
more than 65,000 rms symmetrical amperes at 10% above the maximum rated voltage.

4.2.4 Phase Imbalance

Phase voltage imbalance of the input AC source can cause unbalanced currents and excessive heat in the
drive’s input rectifier diodes and DC bus capacitors. Phase imbalance can also damage motors running
directly across the line. The phase imbalance should not exceed 2% of the voltage rating.

CAUTION

EQUIPMENT DAMAGE HAZARD
Never use power-factor correction capacitors on motor terminals T1/U, T2/
V, or T3/W of the Vacon 50X AC drive. Doing so will damage the

semiconductors.
Failure to follow this instruction can result in injury or equipment damage.

4.2.5 Single-phase Operation

Vacon 50X AC drive 230 Vac models are designed for both three-phase and singlephase input power. If
one of these models is operated with single-phase power, use any two line input terminals. The output of
the device will always be three-phase.

The safe derating of the Vacon 50X series of drives is 50% of the nominal current (hp) rating. Consult the
factory with the particular application details for exact derating by model.

4.2.6 Ground Fault Circuit Interrupters

Vacon 50X drives rated for 230 Vac are not designed to operate with ground fault circuit interrupters (GF­CI). The GFCI breakers are designed for residential use to protect personnel from stray currents to
ground. Most GFCI breakers will shut off at 5 mA of leakage. It is not uncommon for an AC drive to have
30 to 60 mA of leakage.

4.2.7 Motor Lead Length

The distance from the Vacon 50X drive to the motor should not exceed 300 meters. If the leads for motor
connections exceed 30 meters, the motor windings may be subjected to voltage stresses two to three
times nominal values unless an output filter is utilized. Consult with the motor manufacturer to ensure
compatibility. Line disturbance and noise can be present in motor wiring of any distance. The carrier fre­quency for the drive should also be reduced using parameter 803 (PWM Frequency).

Nuisance trips can occur due to capacitive current flow to ground.

Some applications can have a restricted lead length because of type of wire, motor type, or wiring place­ment. Consult VACON and the motor manufacturer for additional information.

4.2.8 Using Output Contactors

Contactors in the output wiring of an AC drive may be needed as part of the approved safety circuit. Prob­lems can arise if these contactors are opened for the safety circuit and the drive is left in run mode of
operation. When the contactor is open, the drive is in a no-load, no-resistance state, but is still trying to
supply current to the motor. However, when the contactor closes, the drive sees the motor resistance and
instantly demands current. This inrush of current when the contactor closes can fault or cause failure to
the drive.

To prevent problems, interlock an auxiliary contact to the drive's Run or Enable circuit to stop the drive
when the contactor opens. In this way, the drive will be disabled and no inrush will occur when the con­tactor is closed again.

4.3.2 Typical Power Connections

See Section 4.2 starting on page 25 for input line requirements. Note that when testing for a ground fault,
do not short any motor lead (T1/U, T2/V, or T3/W) back to an input phase (L1/R, L2/S, or L3/T).

It is necessary to provide fuses and a disconnect switch for the input AC line in accordance with all appli­cable electrical codes. The Vacon 50X AC drive is able to withstand a 150% overload for 60 seconds for
heavy duty rating, and 120% overload for normal duty rating.

The fusing and input protection of the drive must always meet UL, NEC (National Electric Code), CEC (Ca­nadian Electric Code) and local requirements. All fuse ratings included in Table 8 below are for reference
only and do not supersede code requirements. For 230/400 V mains supplies we recommend time-lag
type NEOZED-fuses. The recommended supplier is Bussman.

4.4 Dynamic Braking

The Vacon 50X AC drive is supplied with an integrated dynamic braking (DB) resistor, and is designed to
have adequate dynamic braking for most applications. In cases where short stopping times or high inertia
loads require additional braking capacity, install an external resistor.

NOTE: External braking cannot be added to Size 0 models. For Size 4 (45–75 kW) and Size 5 (90–
150 kW) models, additional external dynamic braking requires a kit that provides the connec­tions to the braking transistors. The XDBKITS4 and XDBKITS5 kits can be purchased through
VACON .

• Starting from size 1 the internal DB resistor can be replaced by an external DB
resistor.

• The terminal identifications of the DB resistor are “B+” and “DB”.

• On the size 1 the DB resistor is connected by fast-on terminals 6.35 mm (see Figure
9 on page 28).

• Starting from size 2 the DB resistor is connected by 2 separate terminals (see
Figure 3 on page 29). The internal DB resistor is connected by fast-on terminals “J3/
DB” and “J4/B+”, which are placed on the power board (right and left side of the
display).

To install an external resistor, first disconnect the internal DB resistor and properly terminate the wires
leading to it. Connect now the external resistance over the connections planned for it.

Changes to Parameter 410 must be made when using external DB resistors.

Verify with the manufacturer of the selected resistor that the resistor is appropriate for your application.
Contact VACON Application Engineering for further assistance with other possible sizing limitations.

Refer to Table 9 below for information about dynamic braking capacity for each Vacon 50X model.

4.5.1 Description of the Control Terminals

Figure 12 shows the control terminals found on the I/O board of the Vacon 50X AC drive. See page 9 for
specifications. Table 10 on page 33 describes the control terminals.

The drive’s control terminals are referenced to earth ground through a resistor / capacitor network. Use
caution when connecting analog signals not referenced to earth ground, especially if the communications
port (J3) is being used. The J3 port includes a common reference that can be connected to earth ground
through the host PLC or computer.

4.6 Reducing Current Surges and Voltage Transients

Inrush currents to coils of magnetic contactors, relays, and solenoids associated with or near the
drive can induce high current spikes in the power and control wiring, causing faulty operation. If this
occurs, a snubber network consisting of a series resistor and capacitor for AC loads, or a freewheeling
or flyback diode for DC loads, can be placed across the relay coil to prevent this condition.
The following component values should be used for 115 VAC or 230 VAC relays or solenoids.

5. Keypad Operation and Programming

5.1 Introduction

The Vacon 50X AC drive is pre-programmed to run a standard, 4-pole AC induction motor. For many ap­plications, the drive is ready for use right out of the box with no additional programming needed. The dig­ital keypad controls all operations of the unit. The ten input keys allow “press and run” operation of the
motor (Operation mode) and straightforward programming of the parameters (Program mode).

Figure 19: The Vacon 50X Keypad

To simplify programming, the parameters are grouped into three levels:

The parameter table on page 113 shows the standard settings, the table on page 117 the parameter
names in 5 languages and on page 121 the setti ngs and messages in 5 languages. “Vacon 50X Parameter”
describes the individual parameters starting from page 59.

If you want to get started quickly, see the “Quick Start” section on page 57.

1. Enter Level 1 by pressing the Program (PROG) key at any time. Level 1 allows you
to access the most commonly used parameters.

2. Enter Level 2 by holding down the SHIFT key while pressing the PROG key. Level 2
allows access to all Vacon 50X parameters, including those in Level 1, for applica­tions which require more advanced features.

3. Enter Macro mode by holding the Program (PROG) key down for more than 3 sec­onds. The display then shows “Hold PROG for Macro Mode.” See Chapter 6, “Using
Macro Mode and Getting a Quick Start”, starting on page 49, for more information.

5.2 Keypad Operation

Parameter 201, Input Mode (see page 62), determines whether the Vacon 50X AC drive accepts its Run/
Stop and speed commands from the digital keypad or from the input terminals. Table 12 describes the
function of the keys in Operation mode.

Initiates forward run when pressed momentarily. If the drive is running in reverse
when FWD is pressed, it will decelerate to zero speed, change direction, and accelerate
to the set speed.
The green FWD designation in the key illuminates whenever a FWD command has been
given.
When both the FWD and REV lights are on, the DC braking function is active.

Initiates reverse run when pressed momentarily. If the drive is running in forward
when REV is pressed, it will decelerate to zero speed, change direction, and accelerate
to the set speed. The green REV in the key illuminates whenever a REV command has
been issued. When both the FWD and REV lights are on, the DC braking function is ac­tive.

Causes a Ramp-to-Stop when pressed. Programmable to Coast- to-Stop by parameter
401, Ramp Select (page 67). The red STOP indicator in the key illuminates whenever a
STOP command has been given. If the drive has stopped because of a fault, this indica­tor flashes to call attention to the display.

Press the Jog key to enter Jog mode. The green JOG indicator in the key illuminates
when the drive is in the JOG mode of operation. To jog the motor in either direction,
press either the FWD or REV (if REV is enabled in parameter 202). The motor will oper­ate at the speed programmed in parameter 303. To exit Jog mode, press the JOG key
again.

When the drive is stopped, pressing this key increases the desired running speed.
When the drive is running, pressing this key increases the actual running speed in 0.1
Hz increments. Holding the SHIFT key while pressing the INC (UP arrow) key moves the
decimal place to the left with each press (0.1 Hz, 1.0 Hz, 10.0 Hz increments).

When the drive is stopped, pressing this key decreases the desired running speed.
When the drive is running, pressing the DEC (down arrow) key decreases the actual
running speed in 0.1 Hz increments. Holding the SHIFT key while pressing the DEC key
moves the decimal place to the right with each press (10.0 Hz, 1.0 Hz, 0.1 Hz incre­ments).

NOTE: The operating speed for the drive is stored on Power Down.

Pressing this key while a parameter is displayed allows that parameter to have its val­ue changed by use of the INC and DEC (up and down arrow) keys. The P indicator flash­es to show that the parameter can be programmed. See also the descriptions for the
INC and DEC keys above to see how they work with the SHIFT key.

The ENTER key has no function when the drive is running or stopped. ENTER can be
used to store the speed command so that it is saved through a power-down. To enable
this function, see the description for parameter 802 (Start Options) on page 83.

Whether the drive is running or stopped, pressing this key places the drive in Program
mode. See Table 13 on page 41 for more information on how this key functions.

Pressing this key toggles drive control between the LOCal and REMote control modes,
as selected by parameter 201 (Input mode). It can be configured to shift:

• the Run/Stop command (either FWD or REV)

• the speed reference signal

• both of the above
It can also be set to “disabled,” which is the factory setting. It will operate either in Stop
mode or while the drive is running. If power is removed and reapplied, the memory will
retain the last selected function.

Table 12:Function of Keys in Operation Mode (Vacon 50X Running or Stopped)

You can access Program mode by stopping the Vacon 50X drive and pressing the Program (PROG) key for
Level 1 access; or holding down SHIFT while pressing PROG for Level 2 access. Pressing and holding the
Enter key and then pressing the Program key will show only those parameters that have been changed
from the factory defaults. Table 13 describes the function of the keys in Program mode.

Press this key to have the drive enter Program mode and have Level 1 parameters
available. (To access Level 2 parameters, hold down SHIFT while pressing this key;
to access Macro mode, hold down the PROG key for more than 3 seconds.) Once
Program mode is active, pressing this key at any time returns the drive to the Op­eration mode. If an Access Code has been programmed, it must be entered to pro­ceed with programming. See Parameter 811 (Access Code) (page 85).

NOTE: To see what parameters have changed from the factory default, press EN­TER + PROG. If the display flashes “Factory Defaults,” no parameters have
changed.

In the Program mode, pressing this key scrolls forward through the parameters. If
the P indicator is flashing, it increases the value of the parameter. To change the
scroll rate, hold the SHIFT key at the same time to increase the scroll rate; release
the SHIFT key to return to the normal scroll rate. Press the ENTER key to store the
new value.

In the Program mode, pressing this key scrolls backward through the parameters.
If the P indicator is flashing, it decreases the value of the parameter. To change the
scroll rate, hold the SHIFT key at the same time to increase the scroll rate; release
the SHIFT key to return to the normal scroll rate. Press the ENTER key to store the
new value.

NOTE: If the P indicator on the keypad display is flashing, momentarily pressing
and releasing both the INC and DEC keys at the same time restores the parameter
to the factory default value. Press ENTER to store the new value.

Pressing this key while a parameter is displayed allows that parameter to have its
value changed by use of INC and DEC (up and down arrow) keys. The P indicator
flashes to show that the parameter can be programmed. See also the descriptions
for INC and DEC (up and down arrow) keys above to see how they work with the

This key must be pressed after the value of a parameter has been changed to store
the new value. The display will show “stored” for one second indicating that the
new value has been entered into memory.

NOTE: The Vacon 50X unit allows you to view only those parameters that have
changed. If you press keypad keys ENTER and PROGram simultaneously, only
those parameters that have been changed from the factory defaults will be shown.

The drive is spinning the motor in the forward direction and the speed of the motor is at the
reference frequency.

The drive is spinning the motor in the reverse direction and the speed of the motor is at the
reference frequency.

The drive has an active run signal but the motor is not spinning because the reference
speed to the drive must be 0.0 Hz.

Line-Start Lockout functionality has become active. This means there was an active run
signal during power-up or when a fault was reset. This run signal must be removed before
the Line-Start Lockout functionality will be removed.

The drive is running forward without accelerating, decelerating or residing at the reference
frequency. This means that something is keeping the drive from the reference frequency
(for example, Current Limit).

The drive is running in reverse without accelerating, decelerating or residing at the refer­ence frequency. This means that something is keeping the drive from the reference fre­quency (for example, Current Limit).

The drive is not allowed to run either because the digital input enable is not active or be­cause ARCTIC mode has shut down the run operation.

The drive has not met the input voltage requirements that it needs to be able to run. In other
words,the Bus Voltage of the drive is either too low or too high.

A stop command was given from the keypad when the keypad was not the active control
source. To remove this condition, the run signal to the drive must be removed.

The first character of the second line indicates if the particular parameter can be changed
(P) or only examined (V). If an attempt is made to change data while in the View (V) mode,
the message **NO ACCESS** will appear for one second.

This indicates that while in Programming mode, parameter data can be
changed.

If the drive is in Run mode (FWD or REV) when the PROG key was pressed,
param eters can be viewed, but not changed.

5.3.4 Other Data

The top line gives 16-character description of the parameter being accessed. The parameter number will
flash when data is being changed. Up to 10 characters are used to display the information stored in the
parameter. Some parameters have a unit designator such as:

s Seconds
hHours
C Degrees centigrade
Hz Hertz
% Percent
A Amperes

When the drive stops because of a fault trip, a unique error message will be displayed, along with the
flashing STOP indicator. “Pages,” or screens of information are available concerning the actual fault and
drive status.

“Troubleshooting” on page 101 gives information about fault codes and troubleshooting.

5.4 Keypad Display Window

The keypad display provides information on drive operation and programming. Special symbols provide
further information about drive operation (see the following section). Figure 20 shows an example of the

5.5 Programming

5.5.1 Accessing Parameters

When PROG (or SHIFT+PROG) is pressed after application of power or a fault reset, parameter 201, Input
Mode, is always the first parameter displayed. Figure 21 shows a typical programming display.

Figure 21: Typical Programming Display

If a different parameter is accessed and Program mode is exited, that parameter is the first one displayed
the next time Program mode is entered. The drive remembers a different “last parameter accessed” for
Levels 1 and 2.

5.5.2 Changing the Display Scroll Rate

Pressing the INC or DEC keys (up or down arrows) arrows causes the display to scroll at a slow rate. To
increase the scroll rate, hold the SHIFT key at the same time that you press the INC key. Release the
SHIFT key to return to the slow scroll rate. This procedure works in all programming and operation
modes.

5.5.3 Programming Procedure

To program the value of a parameter, follow these steps:

To program a text parameter, follow these steps:

1. Press the Program (PROG) key to enter Level 1 Program mode. To enter Level 2,
press SHIFT+PROG. The P indicator will appear on the display. You must enter one
level of programming or the other; you cannot switch between levels without exiting
Program mode.

Note that some parameters cannot be changed in Run mode. For example, if you
wish to program parameter 201, Input Mode, you must stop the drive before
beginning programming. Refer to the Parameter Summary Table at the front of
this manual to see which parameters cannot be changed in Run mode (they
appear as shaded entries in the table).

2. Press the INC/DEC keys to access the desired parameter.

3. Press the SHIFT key to allow the value to be changed. The P indicator starts to blink.

4. Press the INC/DEC keys to select the new value.

5. Press the ENTER key to store the new value. The display shows “Stored” for one
second.

6. Press the PROG key to exit the Program mode, or the INC/DEC keys to select a new
parameter.

1. Like other parameters, text parameters use the INC/DEC (up/down arrow) and
SHIFT keys for editing. A line appears under the character that you are changing.

2. Press SHIFT to advance to the next character that you want to change.

3. Use the INC or DEC keys to change the character value.

4. Press ENTER to store the edited text.

5.5.4 Restoring Factory Settings

Whenever a parameter’s value is being changed (noted by the P indicator flashing), the original factory
setting for that parameter may be restored by pressing and releasing both the INC and DEC keys simul­taneously and then pressing the ENTER key.

To restore ALL parameters to factory settings, or to recall a previously stored parameter set, see param­eter 801, Program Number (page 83).

5.5.5 Viewing Parameters That Have Changed

The Vacon 50X unit allows you to view only those parameters that have changed. If you press the ENTER
and PROG keys simultaneously, only those parameters that have been changed from the factory defaults
will be shown. Note that all parameters, regardless of Level 1 or 2 default location, will be shown. If other
parameters need to be changed, press the PROG key to exit this mode in either Level 1 or 2, as needed.

5.5.6 Using Macro Mode

A special Macro programming mode is available with the Vacon 50X series of AC drives. The Macro pro­gramming mode allows you to customize the most common parameters for your application in the Level
1 group. Macro mode provides special parameters for activating modes of operation by macros, program
sequencer, or serial communications.

Parameters that are important to the drive’s operation are also included in the Macro mode. Although
these parameters are also available with standard programming, the Macro mode allows you to quickly
and easily configure the drive with essential parameters.

See “Using Macro Mode and Getting a Quick Start” on page 49, for detailed information about using mac­ros to program the Vacon 50X drive.

5.6 Measuring Stator Resistance (RS Measurement)

5.6.1 Activating Automatic RS Measurement via Keypad

1. Make sure there is no load applied to the motor and that the motor shaft is free to
spin without damage or injury.

2. Enter the Macro programming mode of the Vacon 50X keypad by pressing and hold­ing the PROG key until the parameter “Appl Macro” appears on the keypad. This
takes about two seconds.

3. Scroll through the parameters of the Vacon 50X Macro programming mode and
configure the following parameters to the data provided on the nameplate of the
motor:

• Rated Mtr Volt (509)

• Rated Mtr FLA (510)

• Rated Mtr RPM (511)

• Power Factor (515)

4. Change parameter “Find Mtr Data” (519) to a value of “Motor RS.” At this point, the
RS Measurement will be armed.

5. Exit the Macro programming mode by pressing the PROG key.

6. The Operate screen shows in two ways that an RS Measurement is ready to be
made. First, the Control path status field displays “MEA.” Second, a “Mtr Measure”
warning flashes, both of these signifying that a measurement is about to be taken.

7. Start the RS Measurement by pressing the FWD key. The measurement can only be
made with the FWD key. The FWD/REV terminals and the REV key will not work.

8. The measurement will begin as the drive injects voltage to the motor at zero fre­quency. The test lasts about two seconds.

24-hour support [phone] • Email: [e-mail]

47  vacon keypad operation and programming

9. If the test was successful, the drive will stop and return to the configured control
path. The “Motor RS” parameter will contain a new value that is the calculated re­sistance of the motor.

10. If the test was not successful, the drive will fault with a “RS Meas. Fail” message
(Fault 34). If the test fails, you may want to try the test again with a different “Rated
Mtr FLA” or different Current Limit percentage.

11. If the measurement process fails for any re ason, it is possible to physically measure
motor resistance by using an ohmmeter and dividi ng the result by 2. Then enter this
value manually into parameter 514 (Motor RS).

5.6.2 Activating Automatic RS Measurement via Serial Link (Modbus)

1. Make sure there is no load applied to the motor and that the motor shaft is free to
spin without damage or injury.

2. Configure the following parameters to the data provided on the nameplate of the
motor:

• Rated Mtr Volt (509)

• Rated Mtr FLA (510)

• Rated Mtr RPM (511)

• Power Factor (515)

3. Change parameter “Find Mtr Data” (519) to a value of “Motor RS.” At this point, the
RS Measurement will be armed.

4. Start the RS Measurement by writing a value of 0x0007 to parameter “SIO Cntl
Word” (904).

5. The measurement begins as the drive injects voltage to the motor at zero frequency.
The test lasts about two seconds.

6. If the test was successful, the drive will stop and return to the configured control
path. The “Motor RS” parameter will contain a new value that is the calculated re­sistance of the motor.

7. If the test was not successful, the drive will fault with a “RS Meas. Fail” message
(Fault 34). If the test fails, you may want to try the test again with a different “Rated
Mtr FLA” or different Current Limit percentage.

8. If the measurement process fails for any reason, it is possible to physically measure
motor resistance by using an ohmmeter and dividi ng the result by 2. Then enter this
value manually into parameter 514 (Motor RS).

6. Using Macro Mode and Getting a Quick Start

A special Macro programming mode is available with the Vacon 50X series of AC drives. The Macro pro­gramming mode allows you to customize quickly the most common parameters for your application in
the Level 1 group. Macro mode provides special parameters for activating modes of operation by macros,
program sequencer, or serial communications.

Parameters important to the drive’s operation are also included in Macro mode. Although these param­eters are also available with standard programming, the Macro mode allows you to easily configure the
drive with essential parameters.

Macros configure what advanced functions will be active in the drive. A macro can also change the default
or visibility of a parameter within the programming levels. Parameter 490 (Appl Macro) configures what
macro will be active in the drive. Parameter 491 (Seq Appl) configures the visibility of sequencer param­eters and the time base of the sequencer. Parameter 492 (SIO Visible) configures whether or not SIO pa­rameters are visible. (See page 50.)

6.1 Entering Macro Mode

To enter the Macro mode, press and hold the PROGram key for more than three seconds. The drive then
enters Macro mode and displays “Hold PROG for Macro Mode.” Following is a list of the different macros
available and their features. A description of parameters used in Macro mode begins on page 49.

The Rated Motor Voltage parameter configures the rated motor voltage, and allows a user to
enter the rated voltage from the motor nameplate to p rovide optimal control and protection.
This is usually the amount of voltage delivered to the motor terminals at the setting of 503 (V/
Hz Knee Freq).

Default: ND Rating

The Rated Motor FLA parameter allows a user to enter the rated FLA from the motor name­plate to provide optimal control and protection. This parameter should be configured to the
value on the nameplate of the motor, as that value is used in calculating the percentage of
current at which the drive is operating.

For information on motor timed overload operation, and how Parameter 610 works with it,
see page 78.

6.4 Quick Start

The following procedure is for operators using simple applications, who would like to get started quickly.
Be sure to read and understand all the sections in this chapter before proceeding with these instructions.
If you are using remote operators, substitute the speed potentiometer for the INC and DEC keys (up and
down arrows), and the remote Run/Stop switch for the FWD key in the following instructions.

IMPROPER EQUIPMENT COORDINATION
Verify that proper voltage is connected to the drive before

applying power.
Failure to observe this instruction can result in injury or

CAUTION

1. Follow all precautions and procedures in “Receiving and Installation” on page 19.

2. Find the motor nameplate, and using parameters 509 (Rated Mtr Volt), 510 (Rated
Mtr FLA), 511 (Rated Mtr RPM), and 515 (Power Factor), set up the motor parame­ters appropriately. Parameter 514 (Motor RS) should also be set up accurately so
the drive can run its routine to measure motor stator resistance. (See “Measuring
Stator Resistance (RS Measurement)” on page 46.

3. Apply AC power to the input terminals. For about 2 seconds the display will show all
segments active. The display then changes to zeros.

4. The factory settings are for keypad-only operation in the forward direction – that is,
the REV key is disabled. Press the FWD key, which causes the FWD indicator to il­luminate.

5. Press the INC key to increase the desired running frequency. When the display gets
to 0.1 Hz, the drive starts to produce an output.

6. When the motor starts to turn, check the rotation. If the motor is turning in the
wrong direction, press STOP, remove AC power, and wait for all indicators to go out.
After the STATUS indicator has gone out, reverse any two of the motor leads at T1/
U, T2/V, or T3/W.

7. The Vacon 50X drive is preset to run a typical NEMA B 4-pole induction motor to a
maximum speed of 60.0 Hz with both acceleration and deceleration times set to 5.0
seconds.

8. Use the INC and DEC keys to set the proper running speed of the motor and the FWD
and STOP keys to control its operation.

PT 0-100kHz 0 to 100 kHz pulse train
When the signal range is inverted (that is, the minimum input corresponds to the maxi-

mum output, while the maximum input corresponds to the minimum output).

206 Vin1 Offset Default = 0.00%

Parameter 206, Vin1 Offset, configures the input range (offset) for analog input Vin1 that
will affect speed or torque limit functions. It is expressed as a percentage of the maxi­mum value of the input signal.
Note that if the input signal drops below the offset value or if the input s ignal is lost (if no
offset is configured), fault 22 will be generated. See parameter 222 for options related to
the drive’s response to loss of input signal.

207 Vin1 Span Default = 100%

Parameter 207, the Vin1 Span parameter, is used to alter the input range (span) of the
input signal for analog input Vin1 that will affect speed or torque limit functions. For ex­ample, if parameter 205, Vin1 Config, selects the 0 to 10 Vdc input signal, setting this pa­rameter to 50% reduces it to 0 to 5 Vdc.

208 Cin Config Default = 0-20 mA 50

When the signal range is inverted (that is, the minimum input corresponds to the maxi­mum output, while the maximum input corresponds to the minimum output).

209 Cin Offset Default = 0.0%

Parameter 209, Cin Offset, configures the offset for analog input Cin expressed as a per­centage of the maximum value of the input signal. Note that if the input signal drops be­low the offset value or if the input signal is lost (if no offset is configured), a fault will be
generated.

210 Cin Span Default = 100.0%

Parameter 210, Cin Span, is used to alter the range of the input signal for analog input
Cin. For example, if parameter 208 (Cin Config) selects the 0 to 20 mA input signal, setting
this parameter to 50% reduces it to 0 to 10 mA.

211 Vin2 Config Default = 0-10 V

Parameter 211, Vin2 Config, selects the type of signal for analog input Vin2. Parameters
212 (Vin2 Offset) and 213 (Vin2 Span) may be used to customize the selected range. The
following data values may be assigned to this parameter:

percentage of the maximum value of the input signal. Note that if the input signal drops
below the offset value or if the input signal is lost (if no offset is configured), a fault will
be generated.

213 Vin2 Span Default = 100%

Parameter 213, Vin2 Span, is used to alter the range of the input signal for analog input

214 Vin1 Filter Time Default = 20 ms

This parameter configures the time constant of a first-order filter of the Vin1 analog in­put. When this parameter is a value of 0 ms there is no software filtering of the analog
input. Note that long filter times will create a delay in the drive response to signal chang­es.

215 Cin Filter Time Default = 20 ms

This parameter configures the time constant of a first-order filter of the Cin analog input.
When this parameter is a value of 0 ms there is no software filtering of the analog input.
Note that long filter times will create a delay in the drive response to signal changes.

216 Vin2 Filter Time Default = 20 ms

This parameter configures the time constant of a first-order filter of the Vin2 analog in­put. When this parameter is a value of 0 ms there is no software filtering of the analog
input. Note that long filter times will create a delay in the drive response to signal chang­es.

217 Trim Ref Enable Default =

This parameter enables or disables trimming of the drive reference by an analog input
and selects which analog input will perform the trimming function.
Speed Ref. = Main ref.+(Trim % Factor) x value of parameter 217 x Max Frequency

Parameter Value Description
Disabled No trimming of drive reference
Vin1 Value of Vin1 will be used in the calculation above
Vin2 Value of Vin2 will be used in the calculation above
Cin Value of Cin will be used in the calculation above
Fxd Trim % Value of Fxd Trim % will be used

Note that setting a parameter for a Bipolar input value allows trimming both positive and
negative around the reference value.

218 Trim % Factor Default = 0.0%

This parameter determines the percentage of the analog input signal selected in Param­eter 217, Trim Ref Enable, that will affect the reference signal.

222 Ref Loss Fault Default =

This parameter allows for the control of the drive’s response to a 4-20mA input on either
the Vin1 or Cin input terminals when the input drops below approximately 3mA. The de­fault value is No Fault. The options for this parameter are:

301 Min Frequency Default = 0.0%

Parameter 301, Minimum Frequency, configures the minimum frequency output of the
drive. This parameter governs the minimum frequency when operating from the keypad
or from an analog input. The preset speeds can be set lower than the minimum frequency
in parameter 301.

302 Max Frequency Default: 50 Hz

Parameter 302, the Maximum Frequency parameter, configures the maximum frequency output of the drive.

Preset Freq 1 (Jog Ref)

303
304 Preset Freq 2
305 Preset Freq 3
306 Preset Freq 4
307 Preset Freq 5
308 Preset Freq 6

These parameters configure six preset speeds in addition to the normal reference speed
of the drive (as defined by parameters 201 (Input Mode) and 204 (Ref Select) and the max­imum frequency of the drive (as set with parameter 302, Max Frequency). Thus, in effect,
you may choose to operate the drive at up to eight different speeds.

The eight speeds are selected by a combination of three digital inputs (PS1, PS2, PS3). A
wiring scheme for utilizing preset speeds is provided on page 24 along with a truth table
showing what combination of inputs results in the selection of which speeds.

Note that parameter Parameter 303 (Preset Freq1) also serves as the reference frequen­cy for jogging.

309 Cut-Off Freq Default = 0.0 Hz

This parameter sets the point where the drive no longer attempts to spin the motor. The
range of this parameter is 0.0–5.0 Hz. When the parameter is configured to a value of 0.0
Hz, the drive will operate with no Cut-off Frequency. If the function is enabled, the drive
will be able to ramp up through the cut-off frequency range, as in normal operation. If the
speed command falls below the cut-off frequency, the drive stops “gating” the outputs
and coasts down to zero speed. The keypad display will indicate Zero Speed, and the For­ward or Reverse LED will be lit depending on the command. When the reference returns
to a value greater than the cut-off frequency, the drive will ramp from 0.0 Hz to the ref­erence frequency.

401 Ramp Select Default: ART-DI

The Ramp Select parameter configures when the alternate ramps of the drive will be ac­tive and whether the drive ramps to stop, or coasts to stop. The following data values may
be assigned to this parameter:

405 Decel Time 2 Default: 3.0 s

This parameter provides an alternate ramping time for the drive when decelerating, con­figuring the length of time to decelerate from the value of parameter 302 (Max Frequen­cy) to 0 Hz. This deceleration ramp is selected by parameter 401 (Ramp Select) or
Sequencer Configuration.
Note that extremely short deceleration times may result in nuisance fault trips or may
require an external dynamic brake or regen current limit.

406 DC Inject Config Default: DC at Stop

DC injection braking may be used to stop the motor more quickly than is possible by ei­ther a ramp-to-stop or a coast to-stop. The Vacon 50X drive allows DC braking to be ini­tiated either when a digital input assigned to DC braking becomes true, when a specified
frequency is reached, or when either of these events occurs.
When using a digital input for DC braking, you must use one of the DI parameters to con­figure the selected digital input for DC braking. The amount of braking force is set by pa­rameter 408 (DC Inject Level). The length of time that the braking force is applied is
determined by the time that the selected digital input is active. The second type of DC in­jection braking supported by the Vacon 50X drive is where DC braking occurs at a speci­fied frequency. The duration of the braking is adjusted by parameter 407 (DC Inject Time).
With this type of braking, as the drive slows down after a Stop command, DC braking be­gins when the frequency reaches the value set in parameter 409 (DC Inj Freq). If the fre­quency at the time of a Stop command is less than that of DC Inj Freq, DC braking begins
immediately. The braking continues for the time period specified by parameter DC Inj
Time. Once the time period elapses, the drive may be restarted.

Parameter Value Description
DC at Stop DC inject only on Stop

DC at Start DC inject only on Start
DC at Both DC inject only on both Start and Stop
DC on Freq DC inject only on Stop below the set frequency

407 DC Inject Time Default: 0.2 sec

If parameter 406 is set to DC at Stop (see page 69), direct current is applied to the motor.
This parameter, DC Inject Time, determines how long the direct current will be applied,
and how long DC is applied at Start if programmed accordingly.
This parameter works in tandem with parameter 410 (DC Inject Config) and the other pa­rameters associated with DC Inject Config. That is, the time period configured by this pa­rameter, DC Inject Time, determines how long DC injection braking will be active. When
DC injection braking is controlled by a digital input, the braking continues for as long as
the digital input is true, plus the time set by parameter 407 (DC Inject Time). When it is
controlled by frequency, however, it continues for the length of time once the drive reach­es the frequency set by parameter 409 (DC Inj Freq).

408 DC Inject Level Default: 50.0%

Configures the amount of DC injection that will occur when direct current is injected into
the motor windings, which acts as a braking force. The amount of current is expressed
as a percentage of nominal motor current. The braking force may be applied when start­ing or stopping. If this parameter is set to 0.0%, the DC injection is disabled.

409 DC Inj Freq Default: 0 Hz

Configures the frequency under which direct current will be applied to the drive when DC
Inject Config is set to “DC on Freq.” If this parameter is set to 0.0, the parameter operates
in the same way as “DC at Stop.”

410 DB Config Default: DB Internal

Determines whether an external or internal dynamic brake is utilized or disabled. The
drive provides an internal dynamic brake (DB) to assist in stopping. If desired, an external
resistor can be connected to DB and B+ for additional capacity. (Note: Size 0 models can­not have an external brake added.)
The following data values may be assigned to this parameter:

Parameter Value Description
DB Internal Internal dynamic braking active

DB External External dynamic braking active
No Dyn Brk Dynamic braking circuit disabled
Int-ARCTIC When DB Conf ig is configured to “Int-ARCTIC,” dynamic brak-

ing becomes active if the drive temperature drops below –7
degrees C. When the DB becomes active, an “ARCTIC Mode”
warning flashes on the keypad. If the drive drops below –10
degrees C, the drive will be disabled and not allowed to run.
The keypad will indicate a “Not enabled” state at this point. If
the drive heats up after being below –10 degrees C, the drive
must meet the following criteria before operating again:

a) Drive temperature must be above –9 degrees C, and
b) Drive temperature must stay above –9 degrees C until a
time period has elapsed. The time period is dependent on how
far below –10 degrees C the drive was. Each degree below –10
degrees C adds another 4 minutes before restart.

414 S Ramp Rounding Default: 25%

This parameter is used to define the amount of rounding or S-curve to the Accel and De­cel ramp. The amount of rounding is split evenly between the beginning and the end of
the ramp. A value of 1% would mean that the rounding of the ramp is near linear. A value
of 50% would have 25% rounding at the start of the ramp and 25% at the end of the ramp.

502 Voltage Boost Default: 1.0%

Parameter 502, Voltage Boost, increases the motor voltage at low speed to increase the
starting torque of the motor. The parameter sets the amount of boost (expressed as a
percentage of the default boost) to be applied at zero frequency. The amount of boost de­creases linearly with increasing speed.
This parameter is used when parameter 501 is set with fixed boost options. For vector
mode this parameter is inactive.

MOTOR OVERHEATING
Too much boost may cause excessive motor currents and motor

overheating.
Use only as much boost as is necessary to start the motor. Auto-

boost may be selected at parameter 501 (V/Hz Select) to provide
optimum value of boost to suit the load automatically.

Failure to observe this instruction can result in equipment damage.

CAUTION

503 V/Hz Knee Freq Default: 50

This parameter sets the point on the frequency scale of the V/Hz curve at which the output
is at full line voltage. Normally, this is set at the base frequency of the motor, but it may
be increased to enlarge the constant torque range on special motors. Setting this param­eter to a higher value can reduce motor losses at low frequencies.

504 Skip Freq Band Default: 0.2 Hz

To reduce mechanical resonances in a drive system, the drive may be configured to
“skip” certain frequencies. Once configured, the drive will accelerate or decelerate
through the prohibited frequency band without settling on any frequency in the band.

The Vacon 50X AC drive provides the capability to configure four prohibited frequency
bands. Parameter 504 (Skip Freq Band), the Skip Frequency Band parameter, sets the
width of the band above and below each of the prohibited frequencies set in parameters
505, 506, 507, and 508 (Skip Freq 1, 2, 3, 4).

For example, if this parameter is set to its default value of 1 Hz and parameter 505 (Skip
Freq 1) is set to 20 Hz, a skip band from 19 to 21 Hz is established.

505 Skip Freq 1
506 Skip Freq 2
507 Skip Freq 3
508 Skip Freq 4

As discussed in the description of parameter 504 (Skip Freq Band), the drive may be con­figured to skip certain frequencies. These three parameters set the center of the three
skip frequency bands (with the width of each band being twice the value of parameter 504
– an equal amount above and below the skip frequency).

For example, if parameter 504 is set to 2.5 Hz and parameter 508 (Skip Freq 4) is set to
55 Hz, a skip band from 52.5 to 57.5 Hz is established.

509 Rated Mtr Volt Default: Model dependent

The Rated Motor Voltage parameter configures the rated motor voltage, and allows a
user to enter the rated voltage from the motor nameplate to provide optimal control and
protection. This is usually the amount of voltage delivered to the motor terminals at the
setting of 503 (V/Hz Knee Freq).

510 Rated Mtr FLA Default: ND Rating

The Rated Motor FLA parameter allows a user to enter the rated FLA from the motor
nameplate to provide optimal control and protection. This parameter should be config­ured to the value on the nameplate of the motor, as that value is used in calculating the
percentage of current at which the drive is operating.
For information on motor timed overload operation, and how Parameter 610 works with
it, see page 78.

511 Rated Mtr RPM Default: 1450 rpm

This parameter replaces the slip compensation parameter setting of the drive so the user
does not need to calculate it.

512 Midpoint Freq Default: 50.0 Hz

When parameter 501, V/Hz Select, is configured to “Linear 2pc,” this parameter, together
with parameter 513, Midpoint Volt, defines an additional point in the V/Hz characteristic.

513 Midpoint Volt Default: 100.0%

When parameter 501, V/Hz Select, is configured to “Linear 2pc,” this parameter, along
with parameter 512, Midpoint Freq, defines an additional point in the V/Hz characteristic.

514 Motor RS Default: Model dependent

This parameter allows direct entry of the Stator Resistance (Rs) of the motor for better
vector performance. The motor manufacturer can provide this information, or you can
physically measure this value with an ohmmeter. From the line-to-line measurement of
motor resistance, enter half the measured value. (See page 46 for more information.)

515 Power Factor Default: 0.80

Parameter 516 permits activation of slip compensation for better speed regulation. The

motor rated speed must be entered into parameter 511 (Rated Mtr RPM) for best results.

Yes Single phase operation. No phase loss.

519 Find Mtr Data Default: Not active

This parameter activates the drive’s ability to measure the stator resistance of the at­tached motor. The automatic stator resistance measurement can be performed either
through the keypad or through the serial link. See “Measuring Stator Resistance (RS
Measurement)” on page 46 for more information about this parameter. The following
data values may be assigned:

Parameter Value Description
Not Active No stator RS measurement.

Motor RS Automatic RS measurement using macro procedure.

520 Filter FStator Default: 8 ms

This parameter filters the stator frequency applied to the motor, which can help tune the
acceleration behavior of the motor. This is particularly helpful when using short ramps
and operating the motor at a frequency above the “V/Hz Knee Freq” (parameter 503) val­ue (field weakening area). Lower values allow dynamic currents to be produced, but with
greater peaks. This could produce unstable states in the field weakening area. Low val­ues for this parameter can cause overcurrent faults while accelerating to frequencies
over the Knee Frequency. Higher values allow the drive to run more smoothly at frequen­cies over the Knee Frequency and protect the drive against overcurrents – often the case
when using special motors or spindle drives.

521 Start Field En Default: No

Parameter Value Description
No The shaft will begin rotating after receiving a Start command,

without delay. If the application has heavy load conditions or
short ramp times, this setting can produce very large starting
currents, to overcome the inertia of the system. This may pro­duce nuisance trips when starting.

522 Filter Time Slip Default: 100 ms

This parameter filters the slip frequency applied to the motor, which can help improve
the dynamic response of the drive. This parameter produces the following results based
on the parameter value:
If the parameter is configured to 100 ms, the drive will produce stable conditions to a
change in load, in most cases.
If the parameter is configured to less than 100 ms, the drive will be able to react quickly
to a change in load, but may over-compensate its reaction to the load.
If the parameter is configured to greater than 100 ms, the drive will react very slowly to
a change in load and will need a longer time to compensate for the difference between
the setpoint and the actual frequency.

523 Id Percent Default: Read-only

This parameter shows the Flux producing current (as a percentage of motor rated cur­rent) that is being applied to the drive.

524 Iq Percent Default: Read-only

This parameter shows the Torque producing current (as a percentage of motor rated cur­rent) that is being applied to the drive.

608 Restart Number
609 Restart Delay

You may configure the drive to attempt to re-start a specified number of times after cer­tain faults occur. Chapter 8 lists all faults and notes which ones may be reset automati­cally.

The number of attempts at re-starting is set with parameter 608 (Restart Number). A val­ue of 0 prevents the drive from attempting a re-start). The time duration that must elapse
between re-start attempts is set with parameter 609 (Restart Delay). The type of start to
be attempted is set with parameter 802 (Start Options); see page 83).

If the number of attempted re-starts is exceeded, the drive will trip with a fault and will
stop operating. Resetting the fault can result in instant starting. (See page 101 for more
information on faults and troubleshooting.)

Note that for 2-wire operation, the FWD or REV terminal must still be active for the drive
to attempt a re-start.

Also note that the counter for attempted re-starts will not reset to zero until ten minutes
after a successful re-start.

613 Max Regen Ramp Default: 300%

This parameter operates as a percentage of the longest ramp time. This time then de­fines the amount of time a deceleration to stop can take without causing a “Regen Time­out” fault. For example, if “Decel Time 1” is 5.0 seconds, “Decel Time 2” is 10.0 seconds,
and “Max Regen Ramp” is 300%, a deceleration to stop that takes more than 30 seconds
will cause a “Regen Timeout” fault in the drive.

When using any of the Time functions, these refer to “Retention Time.” Retention time is
an inverse function: as speed goes up, time goes down, and vice versa. It is typically used
in oven-type applications. The value set in parameter 809 (Display Scale) references the
time of operation when running at Max. Frequency. For instance, if parameter 302 (Max.
Frequency) is set for 60 Hz, 804 (Display Mode) is set for Time min, and 809 (Display Scale)
is set for 600, the scales of the display will read 60.0 min at maximum speed and increase
in time (in minutes) up to the maximum scale of 6553.5 at minimum frequency.

805 Display Units(1) Default: RPM: 1

This parameter determines the three-character customer display units used when pa­rameter 804 is set to User Units. The last digit indicates the number of decimal places to
be shown on the display. Up to three decimal places are possible.

811 Access Code Default: 0

The security Access Code allows the user to control access to the programmable func­tions of the inverter. The initial value of this parameter is 000, which signifies that no ac­cess code is necessary. Any number between 001 and 999 may be used for an access
code, but is not necessary. If an access code is entered, you will not be able to view the
values while scrolling through parameters. Only after the Shift key is pressed will the ac­tual value appear.

To enter an access code, re-program parameter 811 as you would any other parameter.
After the new value is stored, you have 10 minutes of free access. If you remove power
and then restore it, you will need to enter the access code to change any program param­eter. If you enter an incorrect access code, the drive displays **WRONG CODE** and al­lows only viewing rights to the various parameters. Once the correct code is entered, you
again have 10 minutes of free access unless power is removed and restored. To disable
the access code requirement, set parameter 811 back to 000.

812 Freq Ref Output Default: 6FS

The Frequency Reference Output parameter determines the frequency pulse-train out­put from the DOP terminal. This digital output is a pulse train that can be linked to anoth­er drive or to a field meter for speed indication. The pulse train is a 50% duty cycle signal
and requires a pull-up resistor of approximately 4.7 kOhms.
The following data values may be assigned to this parameter:

813 Speed Ratio Default: 100.0%

The Master / Follower Speed Ratio parameter allows the pulse train output of one Vacon
50X series drive (master) to be used to control the speed of up to 8 other follower drives.
The output of each follower can be individually programmed, or trimmed “ON-THE-FLY”
with A2-RATIO. The range of adjustment is 0–200% of the master. This function only
works when using the 6FS or 48FS functions in parameter 204.

7.4 Using the Vacon 50X Program Sequencer

The Vacon 50X AC drive offers functionality that allows users to program up to nine independent operation
states of the drive. This functionality is called the “program sequencer” because it allows the drive to se­quence through the operation states programmed by the user. The Vacon 50X Program Sequencer can be
used in applications that would normally require external intelligence, such as a simple programmable
logic controller.

7.4.1 Enabling the Vacon 50X Program Sequencer

The Vacon 50X Program Sequencer can be enabled with parameter 491 (Seq Appl), found in the Applica­tion Macro programming mode of the Vacon 50X keypad. This parameter configures:

• Whether the sequencer is enabled,

• The time base used for all timing of the sequencer,

• Whether other sequencer parameters are visible in Level 2 programming.

Table 2 shows the options for this parameter:

7.4.2 Controlling the Vacon 50X Program Sequencer

The Program Sequencer can be activated and controlled from either the keypad or the terminal strip. It
is not possible to control the sequencer through the serial link. The control method of the program se­quencer is determined by parameter 201, Input Mode. Setting the Input Mode parameter also allows
switching from Sequencer mode to normal keypad operation by way of the Local/Remote switch. Table 3
illustrates possible program sequencer control configurations.

Keypad Control (Activation) of the Vacon 50X Program Sequencer

When activating or controlling the Vacon 50X Program Sequencer from the keypad, pressing the FWD key
commands the drive to cycle through the programmed states of the sequencer one time only (oneshot
operation). One-shot operation will run the sequencer until state 9 is reached, or until any state that is
not changed from the default is reached.

Pressing the SHIFT and FWD keys simultaneously causes the programmed sequence to repeat until the
Stop key is pressed (continuous operation). In continuous mode, the sequencer runs until state 9 or any
state that is not changed from the default is reached; it then jumps back to state 1.

Note that the REV key has no function in the sequencer mode.

Terminal Control of the Vacon 50X Program Sequencer

When activating or controlling the Vacon 50X Program Sequencer from terminals, continuous and one­shot operation is determined by whether the drive is wired for 2-wire or 3-wire control. If the terminal is
set up for 2-wire control, the sequencer operates in continuous mode (R/J terminal inactive). This will run
the sequencer until the Forward command is removed. If the terminal is set up for 3-wire control, the se­quencer runs one cycle when the FWD terminal is activated.

Note that the REV terminal has no function in sequencer mode.

Vacon 50X Sequencer Dwell Functionality

The Vacon 50X sequencer has the capability to dwell, or pause, in a state and disregard any command to
advance to the next state. This can be done in two different ways, and both methods can be used at the
same time.

If the sequencer is actively running and the Enter key is pressed from the Operate screen of the Vacon
50X keypad, the sequencer will dwell in the current state (it will never advance to the next state). While
the sequencer is dwelling, a warning of “Seq Dwell” will flash on the Operate screen. To leave the dwell
state, press the Enter key again from the Operate screen.

The sequencer Dwell mode can also be entered by programming a digital input to “Seq Dwell.” The se­quencer will then dwell in the current state, for as long as the digital input is active.

Vacon 50X Sequencer Advance Functionality

The sequencer has the ability to allow the user to advance to the next state without satisfying the condi­tions programmed to advance. To do this, program a digital input to “Seq Advance.” When a digital input
program to this option changes from inactive to active, a running sequencer will advance one state. This
feature is useful when debugging a sequence with long time intervals.

7.4.3 Sequencer State Configuration Overview

Each state of the program sequencer is defined by five characteristics:

• Direction in which the drive will operate

• Speed at which the drive will operate

• Ramp selection of the drive

• Output configuration (relays and digital outputs) of the drive

These five characteristics are configured by two parameters for each state. These parameters are
named “Seq Cntl X” and “Seq Count X,” where X represents the state number of the sequencer. The “Seq
Cntl X” parameter is a binary parameter that sets each of the five characteristics listed above. “Seq
Count X” configures the threshold that the sequencer will use in determining when to advance by the

Vacon 50X Sequencer Ramping Selection

When the sequencer is active, the active ramp is no longer determined by parameter “Ramp Select.” The
user, however, does have the choice of using the main ramps (Accel Time 1/Decel Time1), or the alternate
ramps (Accel Time 2/Decel Time 2) for each independent state. This is determined by bit 3 of the control
parameter. If bit 3 is set to 1, then the alternate ramps are used (Accel Time 2/Decel Time 2).

Sequencer Output Configuration

The Vacon 50X Program Sequencer allows digital outputs to be activated during states of the sequencer.
This function could be used to activate other devices in a system or to signal to an operator when a part
of the sequence is active. The user sets the digital output by setting bits 9 and 10 of the control parameter
with a binary value, and then sets a digital output parameter with the option for that same binary value.
For example, if a control state was output configured for a binary value of 11, then any digital output con­figured to “SeqOut-11” would be activated during that time.

Sequencer Direction Selection

The sequencer allows each state to be configured as running Forward, Reverse, Stopped, or DC Injected
by setting bits 7 and 8 of the control parameters.

Sequencer State Duration

Bits 4, 5, and 6 of each sequencer control parameter specify how that step will allow advancement to the
next step. The options for advancement are time, pulse input, voltage threshold, current threshold, or
digital input comparison. After the advancement method is selected with these bits, the threshold of ad­vancement is determined by the state’s count parameter (see the next paragraph).

Sequencer State Advance Threshold (via Count Parameter)

The sequencer count parameters work in conjunction with the state duration configuration in the control
parameter to determine when to advance to the next state. The function of this parameter is dependent
on the state duration configuration as defined in Table 6 on page 96. The range of data programmed into
this parameter can be from 0 to 65,535, and can represent time, pulse counts, analog voltage thresholds,
analog current thresholds, or digital comparison values.

Description of Seq Count Function

Time Base – The current sequencer state will last for a time interval equal to the number “Seq
Count X” multiplied by the time base configured in the Seq Appl parameter.

Seq Appl Setting Time to Advance Maximum Sequence Time

1 sec Base (1 sec) * (Seq Count X) 18.2 hours

.1 sec Base (0.1 sec) * (Seq Count X) 1.82 hours

0.01 sec Base (0.01 sec) * (Seq Count X) 10.92 minutes

Pulse Count – The current sequencer state will last until the number of pulses programmed into
“Seq Count X” is detected on terminal Vin1.

Low Analog Voltage Threshold – The active sequencer state lasts until the voltage signal applied
to terminal Vin2 is < a value programmed into “Seq Count X.” The value programmed into “Seq
Count X” should be the percentage of input after span and offset are applied (where 100.00% =

10000).
Note: The % of analog input after span and offset can be read in parameter 912, Vin2 Status.

High Analog Voltage Threshold – The active sequencer state lasts until the voltage signal applied
to terminal Vin2 is > a value programmed into “Seq Count X.” The value programmed into “Seq
Count X” should be the percentage of input after span and offset are applied (where 100.00% =

10000).
Note: The % of analog input after span and offset can be read in parameter 912, Vin2 Status.

Low Analog Current Threshold – The active sequencer state lasts until the current signal applied
to Cin terminals is < a value programmed into “Seq Count X.” The value programmed into “Seq
Count X” should be the percentage of input after span and offset are applied (where 100.00% =

10000).
Note: The % of analog input after span and offset can be read in parameter 911, Cin Status.

High Analog Current Threshold – The active sequencer state lasts until the current signal applied
to Cin terminals is > a value programmed into “Seq Count X.” The value programmed into “Seq
Count X” should be the percentage of input after span and offset are applied (where 100.00% =

10000).
Note: The % of analog input after span and offset can be read in parameter 911, Cin Status.

Digital Comparison – The active sequencer state lasts until the binary value of digital inputs
configured to Seq1, Seq2, and Seq3 is equal to the value programmed into “Seq Count X.”
Note: For this option to work, “DIx Configure” parameters must be set to “Seq1,” “Seq2,” and
“Seq3.”

When the sequencer is running, a warning, “Seq Running,” will flash on the screen to indicate that the
drive control state may change without user input. For example:

SQ1: Stopped SQ1: Seq Runni ng

When the sequencer is dwelling (pausing) in a state, a warning, “Seq Dwell,” will flash on the screen to
indicate that the sequencer will not advance. For example:

SQ1: St o pp e d SQ1: Seq Dwel l

7.4.5 Sample Sequencer Program

A machine is required to run in the forward direction at 50 Hz for one hour, then quickly decelerate to a
stop. While stopped, a digital output must be enabled to sound an alarm to an operator. After two minutes,
the machine must accelerate in the reverse direction to 5 Hz until a limit switch is activated, causing the
drive to decelerate to a stop. The following three sequential states can be programmed using only the
drive:

Direction Selection Forward Stop Reverse

Speed Selection 50 Hz Zero speed 5 Hz

Ramp Selection Primary Alternate Primary

Output Configuration SeqOut-00 SeqOut-01 SeqOut-10

State Duration 1 hour 2 minutes Until DI active

First, since two of the sequential states are time-based, the proper setting of the “Seq Appl” parameter
must be determined. Since there is not time required that has resolution needed of less than one second,
the “1 sec Base” option is the easiest to use. If greater resolution is needed (for example, if a state needed
to last for 2.5 seconds), another option should be chosen.

Since the sequence requires use of a digital input and a digital output, two non-sequencer parameters
need to be used. Set the parameter “DI1 Configure” to “Seq1” and the parameter “DO1 Configure” to “Se­qOut-01.”

Since control of the sequencer is only needed from the keypad, the configuration of the “Input Mode” pa­rameter should be “Local Only.”

Required parameter modifications for this program are provided in Table 30, with explanations.
