3. If the inverter will not be placed in service immediately upon receipt, store the device in a dust free environment. Be sure the room is ventilated with cool, dry air. Store this device in its original packing

material whenever possible.

4. Every reasonable precaution is taken during the production, packaging, and shipping of this device to prevent damage to the unit before installation.

If there is any damage upon receipt, contact the dealer and the freight

company immediately.

TOSHIBA

CHAPTER 2 Proper Environment for Installation

2-1

2-2

The VF-SX inverter Is a solid state device. Use caution to install the device in the proper environment, as instructed in the general recommendations shown below. See Chapter 14 for detailed specifications of the proper operating environment.

1. Confirm that the input power supply is within +/- 10% of the nominal voltage. The protective circuit will activate and trip if the permissible input voltage range is exceeded. Extreme voltage conditions may damage the inverter.

2. Do not install the inverter in places where high temperature or humidity are present. Do not install in dusty environments, or environments contaminated with metal particles or metallic powder.

3. Do not mount the inverter on any device subject to intense vibration.

4. Operate the inverter only in an environment between -10 deg C to 40 deg C. The inverter generates heat when operating. When it is installed on a subpanel or backplate be sure there is adequate ventilation on all sides of the inverter, including the back of the inverter where the heat sinks are located. In high ambient temperatures it may be necessary to remove the stick-on seal on the top of the inverter to allow more ventilation through the Inverter.

Certain electrical equipment, if installed too near the inverter, may

cause malfunctions. Examples of this type of equipment can include:

If a magnetic contactor is installed near the inverter install a

urge suppression device across the coil of the contactor to prevent surging magnetic fields from interfering with the operation of the inverter.

Do not install the inverter near fluorescent lighting.

Keep other heat generating electrical equipment, such as resistors

or heaters, away from the inverter.

Always properly ground the inverter chassis to prevent electrical noise

and nuisance tripping. Proper earth ground should not exceed 100 ohms.

Install the inverter ONLY on incombustible subpanels, such as a metal

7. subpanel. If the inverter is installed on a heat insulating subpanel then mount the inverter on a metal subpanel first, and attach this assembly to the insulated subpanel.

Always have at least 10 centimeters free space above and below the

inverter. Always have at least 5 centimeters free space on EACH side of the inverter. If more than one inverter is mounted in a row, leave at least 10 centimeters between each drive, from side to side. If fans are installed in the enclosure or near the drives this space requirement may be reduced. Consult the Toshiba factory for details.

CHAPTER 4 Application Precautions

4-1

4-2

1. If the drive is very lightly loaded (approximately 5*) or if the inertia of the driven load is very small, the drive may become unstable. The result could be abnormal vibration or overcurrent trip. If this condition

persists lower the PWM carrier frequency (parameter [C F]). See Chapter 12 for instructions.

2. Unstable results may occur if:

A. The output rating of the drive is less than the output rating of the

motor.

B. The drive is used with a motor with special ratings, such as an

explosion proof motor, or a motor specially built for high inertia

applications.

C. The drive is used with a pulsing load, such as a load requiring

repeated piston type operation.

3. The motor will coast to stop if the power is lost. If an immediate stop or very quick deceleration of the motor is required use an auxiliary brake device. Select the appropriate stopping method as described in Chapter 11 for an emergency stop.

4. GROUNDING

The inverter should be grounded in accordance with Article 250 of the National Electrical Code or Section 10 of the Canadian Electrical Code, Part I. The grounding conductor should be sized in accordance with NEC

Table 250-95 or CEC, Part I, Table 16.

TOSHIBA

CHAPTER 5 Wiring Guidelines and Precautions

5-1

5-2

This chapter of the manual discusses some of the basic wiring configurations and external devices commonly associated with the installation and application of variable speed drives. Local codes, specifications, requirements, and operating conditions may require the addition of other devices or modifications to the following basic recommendations.

TOSHIBA

5.1 Inverter Wiring

(Refer to Figure 5.1 and 5.2)

1. It can be difficult to remove the upper cover after wiring, so change the jumper selectors J1 or J2 on the internal PC board for "external signal selection" before wiring the inverter. See Chapter 6 for the approximate location of jumpers J1 and J2 inside the drive.

When a signal between 0 to 5V is used as frequency signal, switching the jumper is necessary. Refer to Chapter 10, Table 10-9 for details.

2. Always turn the main line power OFF and confirm that there is no voltage present with a testing tool before connecting power, motor leads, or

control wires.

3. WTOJIN^ Wait until the "CHARGE" lamp has turned off before working on the drive. An internal capacitor stores electrical charge in the inverter and electrocution may result due to inadvertent contact with this

capacitor. Do not touch the terminals or remove the cover while the

"CHARGE" lamp is on. This indicator is located in the lower right-hand

side of the drive near the terminal blocks, and it is a brightly lit red LED when the drive is fully charged.

4. WARNING: Do not wire input power to the output terminals (U, V, W) of the

drive, this will damage the drive. Before energizing, confirm that motor leads are attached to terminals U, V, and W and that the main power leads are attached to terminals R, S, and T.

5. Exercise caution when wiring the control signals, as shown.

A. Install a surge suppressor on any electromagnetic coil on any

contactor wired to the drive. This includes line and load side contactors.

B. Use shielded wire or twisted pair wire for control circuit wiring.

Keep this wire isolated from power wire.

C. Always isolate the input control signals from the main power wiring.

This restriction applies to all control terminals except FLA, FLB, and FLC.

6. Wire sizes:

A. For wire to an ammeter, wire to a frequency meter, and wire carrying

input speed reference signals, use at least 16 gauge shielded wire.

B. For all other control wiring, use at least 12 gauge PVC coated wire.

Figure 5.2 Simplified Power and Control Wiring

Run/Stop

5.2 Installation of a Molded Case Circuit Breaker (MCCB)

1. Install a molded case circuit breaker (HCCB) on the line side of the drive for protection of the incoming power wiring only.

2. Turn the drive ON and OFF via control devices or the touchpad whenever

possible, and not by manual operation of the HCCB or MC. Use the control terminals F. R, and CC to receive control signals from the appropriate remote control devices.

TOSHIBA

5-5

5.3 Installation of a Primary Magnetic Contactor (MC)

1. Install a magnetic contactor (HC) on the line side of the inverter to prevent restart after either a loss of power, a trip of an external overload relay, or an operation of the internal drive protective device.

2. The VF-SX has an internal fault detection relay. The HC can be opened when the inverter protective circuit operates by connecting this contact point to the primary MC operation circuit.

3. The inverter can be used without an HC. In this case use a shunt trip style main breaker (MCCB) and open the main circuit by tripping the breaker when the inverter protective circuitry operates.

4. When using a braking resistor with an overload relay, install an HC or an MCCB with shunt trip on the line side of the inverter. Connect these devices so that the power circuit will open when the internal fault detection relay (Ft) or externally installed overload relay operates. Emergency stop is also possible by connecting the overload relay contact point between the terminals of SS3 (EX) and CC of the inverter. See Chapter 11 for details of the Emergency Stop parameter.

5. Use control signals on terminals F, R, and CC for frequent starting and stopping. Avoid turning the inverter on and off with the primary HC.

6. Always install a surge suppressor across any contactor coil.

5.4 Installation of an Output Magnetic Contactor (MC)

1. Avoid starting and stopping the motor with an output contactor (HC) installed between the inverter and the motor. Excessive surge currents could damage the output devices of the drive. Use control signals on terminals F, R, and CC instead.

2. For Bypass Operation; Be sure the motor has stopped and the drive is OFF before turning on the bypass contactor to run the motor directly from line power. Use an external timer, PLC, or similar device as required. Always make sure that the bypass contactor does not allow voltage to backfeed into the inverter output terminals.

5-6

TOSHIBA

5.5 Installation of an External Overload Relay

1. An electronic overload relay is standard on the VF-SX drive. However, for the following applications Toshiba recomtnends Installing an overload relay that coordinates with the internal solid state relay and the motor connected to the drive. Connect the external relay between the drive and the motor.

A. When using a motor with non-standard current ratings, or the motor

ratings are not comparable to standard duty motors. B. When operating a single motor smaller than the rating of the drive. C. When operating several motors simultaneously from the drive. In this

case Install an overload relay on EACH motor.

2. When applying the VF-SX drive to a constant torque load, change the electronic overload characteristics, or Install a separate overload relay. See

Chapter 11, Parameter [ bHrj.

3. When a motor continuously runs at low speeds it is recommended to use a motor

with an Internal overload relay, for additional protection.

5.6 Installation of an input Reactor

An input reactor Is used to suppress high frequency elements and sudden changes

In power fluctuations. Install an Input reactor when the Inverter Is connected

to electrical systems with the any of the following characteristics:

1. When the power capacity Is 200 KVA or more and the power capacity is

10 times or more than the Inverter capacity.

2. When the Inverter Is connected to the same system as a thyristor commutation type controller.

3. When the inverter Is wired to an electrical system which also contains a distortion source such as an arc furnace or a large capacity inverter.

5.7 Incorrect Wiring and Incorrect External Components

WARHINS: DO NOT INSTALL A POWER FACTOR IHPROVEHENT CAPACITOR ON THE INVERTER INPUT OR OUTPUT. Current and voltage surges associated with the use of power factor capacitors can damage the drive components.

If power factor correction is required add an optional input line reactor to

correct power factor.

TOSHIBA

Radio Freouencv Interference

During operation of the drive there may be noise generated by the drive in the frequency range associated with radio transmission signals. This noise may adversely affect sensitive electronic equipment near the drive. If this condition persists install a RF/EMI (Radio Frequency or Electromagnetic Interference) filter on the input to the drive. Shield the motor leads in metallic conduit. These steps will reduce radio frequency interference. Contact Toshiba for details, or see Chapter 15.

WARWIH6: Do not operate or energize the inverter before checking between the motor and the inverter for mis-wiring or short circuits in the motor. Do not operate the drive if the motor is shorted. Do not ground the neutral point of the motor star

winding.

Setting: In the parameter group [C S fc ] the Comand Mode Selection is set to 2 (only touchpad input valid). In the same parameter group the Frequency

Setting node Selection is set to 1 (only terminal input valid). When the

external signals are input at Terminal IV (see case 3 above), set Teminal IV

Input, also in parameter group [0i~. 5 fc], to 1 (engaged). In this case, the

current input on the IV terminal (4-20mA) will be the standard default setting. When a 0-5V signal is the required control signal, set the jumper JP2 on the PCB to V. When a O-IOV signal is to be chosen the input will be from terminals RR and CC. When using 0-5V set the jumper JPl on the PCB to 5V.

7.1 Definitions of SX Drive Group Parameters

[Cr.U]: USER PARAHETERS

This display shows all parameters which have been phanged from factory preset values. This is a quick, easy way to examine drive parameters and tell at a glance which parameters or functions have been changed, without having to search

through all the menus to examine each parameter and compare the value to the factory preset value.

[ G r. F ]: FUNDAHEHTAL PARAHETERS {See Chapter 9)

This set of values contains adjustable parameters considered "fundamental” to drive operation and application. These include acceleration and deceleration times, base frequency, forward and/or reverse operation, upper and lower operating frequency limits, and options for the Volts Per Hertz (V/f) ratios. The option to reset the drive to all factory preset values or clear all past trips is available from this menu.

[C r. 5 fc]: TERHINAL SELECTION PARAMETERS (See Chapter 10)

This set of values defines how different input and output terminals will function

during drive operation and affect drive operation. Virtually all commands

required for remote control or automatic operation of the drive are found in these parameters. These functions allow the drive to signal when an upper or lower limit has been reached, if the drive is running in forward or reverse, and

if the drive is accelerating or decelerating. Enabling or disabling various control terminals and setting up multiple speed running conditions is available from this menu.

[ C r. P r ]: PROTECTIVE FUNCTION PARAMETERS (See Chapter 11)

This set of values defines the type and amount of motor protection which will be enabled during operation of the motor and driven load. Emergency stop, DC

injection braking, restart or "retry", current and voltage limits, stall enable

and parameters, and trip history are located in these parameters. The programmable settings of the electronic overload as recognized by the National

Electrical Code are included in this section.

[Cr.C C] : CONTROL AND COMMUNICATION PARAMETERS (See Chapter 12)

This set of values identifies critical frequency parameters. These include the PWH carrier frequency, motor tone selection, initial startup frequency, jump frequency for critical resonance protection, automatic torque boost, slip frequency compensation, and frequency hysteresis, which precludes rapid ON/OFF cycling around a setpoint.

[Or .R fl]: METER ADJUSTMENT PARAMETERS (See Chapter 13)

These parameters control and adjust the scaling of the signals which drive remote ammeters or frequency meters, provide bias and gain adjustments, and define the Universal Unit Multiplication Factor, an output scaled to Hz, but user defined to some other parameter other than frequency.

PANEL/

REMOTE

The "PANEL/REHOTE" key is used to switch the SX drive

between panel control (operation from the touchpad) and remote control - control from remote signals attached to the correct input terminal blocks.

The "HON" (Monitor) key is used to make the display show any

monitored value available, such as forward or reverse run, % amps, assigned run frequency, past trip data, or other items. See 8.2.2 in this chapter for a complete explanation.

The "PRG" (Program) key is similarly used to switch the drive from other modes of operation to the "Program’ mode, and thereby allow programming or changing of the numerous parameters as required to match operating conditions.

The "UP ARROW" key is used to increase parameter settings, scroll upwards through program group parameters, or upward through

monitor values.

The "DOWN ARROW’ key is used to decrease parameter setting,

scroll downwards through program group parameters, or downward through monitor values.

The "ENTER" key is used to select or set a value of any

parameter such as run frequency or other data into permanent

memory.

O PANEL CONTROL

The "RUN" key is used to start operation of the drive,

is valid ONLY when the "PANEL CONTROL" LED is lit.

The "STOP/RESET" key stops operation of the drive, when the drive is in "PANEL CONTROL" mode. Emergency stop operation is possible by pressing this key TWICE, when the drive is in any other mode. The inverter is reset from this key (depress for 1 second, minimum) after a trip.

This 7 segment, 4 digit LED display shows operating frequency in DRIVE mode, the status of a variety of data in the MONITOR mode, the title of the parameter groups, and the values of these parameters

in the PROGRAMMING mode. In the event of a trip, the cause of this trip is displayed. The "Hz", "SEC", "X", or "PANEL CONTROL" LED’s will be illuminated as appropriate in all modes.

8.2 Display Modes

The Toshiba Model SX inverter has four types of operation and display modes, as shown below:

1. Drive Mode

2. Monitor Mode

3. Programming Mode

4. Jogging Mode

For basic drive operation, this section of the manual will discuss all of these

modes as they apply when using the touchpad to operate the drive. There are many

options for remote control of the drive discussed in later chapters of this

manual.

Enter Monitor Mode by pressing the l“°"l key. To re-enter Drive Mode press thpl I

key again. Enter Programming Mode by pressing the s key. To return to Drive

Mode press the E^Z] key again. If there is no input within 3 seconds from

depressing the or the drive will automatically return to Drive Mode

and display the frequency.

TOSHIBA

8-5

8.2.1 Drive Mode

The Drive Mode is automatically selected every time power is initiated to the drive. In this mode the inverter output frequency monitoring and the frequency setting coraniand value is taken from non-volatile memory and implemented. A status warning (indicating a possible trip] is displayed during operation, if this condition is warranted. Trip information for any type of trip is displayed

whenever the inverter is tripped OFF. The LED monitor display will show these

trip codes.

If no warning or trip has occurred the LED display shows the frequency value.

This is the frequency which the drive sends to the motor. When the drive is

first energized the display will read 0.0. The "HZ" LED beneath the LED

display will be lit, indicating the display is showing a value of frequency.

A status warning indicator is a one of three flashing characters to the left of the frequency in the LED display. These characters indicate an overcurrent condition, an overvoltage condition, or an overload condition. Under most circumstances, if these conditions are not cleared the drive will eventually trip.

If the drive does trip, the trip code indicating the cause of that particular trip will be displayed on the LED monitor display. See Chart 1 below for a summary of all trip codes. See Chapter 16 for a brief discussion about potential solutions to drive trips.

1. Setting or Changing an Output Frequency

To implement a frequency change press the or keys while the drive is in the Drive Mode. If the frequency command value is changed during operation, the operating frequency will also change accordingly. If the frequency command value is different from the operating frequency then acceleration or deceleration

will occur, based on the accel/decel time parameters currently programmed in the drive. It is possible to prevent a frequency change from the touchpad, by

changing the parameter Frequency Setting Mode Selection [FHOd]. See

Chapter 10.

2. Status Warning

A warning character and a frequency value are sometimes displayed alternately on the LED display when running in the drive mode. The following three warning characters can be displayed:

[C]

.....

When a current more than the overcurrent stall level is detected.

[P]

When a voltage more than the overvoltage stall level is detected.

[L]

.....

When the overload trip parameter ( tHr ) calculates that output

current has exceeded more than approximately 75X of the trip value.

8-6

These alarm displays will turn off automatically when the alarm conditions no longer exist. Typically, the drive will eventually trip OFF if any one of these conditions persists. See section 8.8 in this chapter for more details.

3. Trip Information

If the VF-SX drive trips while in the Drive Mode, the cause or type of this trip will be displayed immediately on the LED monitor display. The display will continuously flash a trip code indicating the cause of the trip. Furthermore, the registered trip status can be read out from drive memory.

The flashing trip display will remain on continuously until the power is turned "OFF" or the trip is cleared. Refer to Section 8.7 — Error Reset, (in this chapter) for instructions to clear a trip, return to the Drive Mode, and run the

drive.

Table 8-1 below shows a list of all trip codes which the drive can display. This information is also available in the Appendix.

Table 8-2 below shows an example of a drive trip occurrence, and of the data stored for examination in drive memory when a trip occurs. Six other parameters describing the software versions and past'trip history can also be observed by

stepping further into the menu shown in this Table. Press the or keys

to scroll through this data. If the I“”"! key is pressed next the initial trip code will be shown.

If the or keys are pressed continuously during this procedure, the

displayed item will change every 0.5 seconds and display in order. The display

can be changed to the trip information display status by pressing the key at any time during this procedure.

8.3 PANEL/REMOTE Control

Either the "PANEL" mode or the "REMOTE" mode of drive control may be selected.

In the "REMOTE" mode any commands from the touchpad are ignored (except EMERGENCY

STOP). A brief explanation of the Emergency Stop function is shown in Section

8.4 in this chapter. See Chapter 11.3 for a complete explanation of the EMERGENCY STOP function.

In the "PANEL" mode all commands from control signals connected to the terminal

blocks are ignored, including speed pots and 4-20mA input signals.

Switching between the "PANEL" and "REMOTE" modes is accomplished with thel^SI!] key on the touchpad. This setting can only be changed while the drive is

stopped. The LED display shows 0.0 when the drive is stopped.

The Comand Mode can be set so that "PANEL" control or "REMOTE" control is never

possible. See Chapter 10, parameter [ cnod ], for an explanation.

When power is first turned ON the drive is energized in the drive mode. If the drive is controlled from the touchpad the LED indicating "PANEL CONTROL" will be

illuminated. If the drive is not controlled by the touchpad this LED will not

be on, and the drive will accept input control signals from the terminal blocks.

TOSHIBA

The Emergency Stop command Is a command to forcibly stop the operation by depressing the Inverter unit keys on the touchpad when the drive Is not controlled from the touchpad. This cannot be prohibited by any setting of the Command Mode. The emergency stop will be regarded as a trip and will be registered as a past error In the trip history section of the drive memory.____________________________________________________________________

8.5 Starting the Drive from the Touchpad

After confirming all wiring Is connected to the proper terminals, the Inverter may be operated using factory default settings, via the touchpad. This Is the most simple mode of operation for the Inverter. This can serve as a simple test for the Inverter/load combination. (See Chapter 6 for a brief look at the most simple methods of control and power wiring for the drive.)

The factory default settings for all parameters are shown In Chapter 7.

It Is recommended to start the Initial run at a low frequency/speed for any test

operation.

Table 8-5 shows the touchpad keystroke sequency for starting the drive.

8.7 Error Reset

In the event that the Inverter should trip, the fault relay (Ft) will change state. See Part 9 or this chapter for more information about the fault relay.

The inverter can be reset after a trip, by removing the cause of the trip. To

reset a trip perform any of the following steps:

1. Turn off incoming power to the inverter for at least 10 seconds.

2. Provide momentary "short circuit" or jumper between terminals RST and CC.

3. Reset the drive from the EHn key on the touchpad.

The touchpad key will clear a fault when operated as shown in Table 8-7.

Function

[ C L i~] appears on the LED display.

Momentarily depress the same key. The drive will clear and reset itself, when all trip causes and errors have been removed.

NOTE: Some drive trip occurrences are caused by a timed overload calculation in drive software. Usually this condition is due to the motor being operated in a overcurrent condition, which may cause an unsafe level of motor heating. If this calculation determines that the motor may still be too hot to re-energize, then the drive will not reset until enough time has passed for the motor to cool down.

In some cases this period can last for several minutes, preventing reset for this

length of time.

If this drive/motor overload combination occurs the drive monitor LED display will continue to display the trip indication parameter, even after the reset procedure shown in Table 8-7 is implemented, until the drive software will allow a reset.

8.8 Warning Displays

When attempting to set a frequency parameter using the and keys, it is possible to try to adjust some parameters above or below certain limiting values. If this occurs the drive will alternately display the maximum or minimum

frequency available and warning indicators [H/ ] or [t.0].

[H I ] Warning: The setting value is beyond its upper limit or the

[L 0] Warning: The setting value is beyond its lower limit or the

Frequency parameters that are limited by the [F H] (Maximum Frequency),

[ i. L ] (Lower Limit), or lUL ] (Upper Limit) cannot be set to exceed these values. An example of this type of frequency parameter would be the multispeed run frequencies. (See Chapter 10). In some cases, the set value may be exceeded

as a result of changing the [ FH], lULi. and/or [L L] values. In this

case, if the parameter that has exceeded the range is selected, a warning will

be displayed, but only when this parameter is viewed, and the or iteyj are depressed. When either of these keys is depressed the set value will change to the value in the normal range.

When higher than [U L], the same value as [U L] is set.

When lower than [ L L ], the same value as [ L L ] is set.

BE SURF THF MOTOR IS NOT RUNNING DURING THE FOII OWING PROCEDURE.

As an example, hold the key dovm, as if setting the frequency to a higher

lULj setting. Then, this frequency and the [H I ] warning will alternate on

the LED display.

current set value exceeds its upper limit by changing any parameter. If this is the case the value will "self-correct" to the maximum acceptable setting.

current set value exceeds its lower limit by changing any parameter. If this is the case the value will "self-correct" to the minimum acceptable setting.

TOSHIBA

Be sure to reset the frequency to a lower value before actually starting the

motor.

Other possible warning displays are:

[C]: A current more than the overcurrent stall level has been detected.

8-19

[P]

[<-]

A voltage more than the overvoltage stall level has been detected.

This LED character Is displayed when the overload [ t H f~ ] trip value has reached more than approximately 75% of the trip value.

8.9 Fault Relay Information

The VF-SX drive has an Internal fault relay (FL), which Indicates that the drive has tripped. The possible causes of trips are shown in Table 8-1 of this chapter. Possible solutions to trips are shown in Chapter 16. Part 7 of this chapter details the procedure to reset the drive In the event of a trip.

When the protective function operates and the inverter trips the trip cause will

be shown on the LED monitor display. This is a visual confirmation of a trip. The fault relay provides electrical confirmation and indication of a tripped

condition. The fault detection signal Is output at the (FL) relay contact

points. See Figure 8.2 below.

The Toshiba VF-SX drive has numerous built in features, operator adjustable parameters, and adjustable functions. Select and adjust these features as required to match each unique application.

TOSHIBA

Chapter 7 lists the adjustable range of all parameters and the standard factory default values of each parameter. The function and intent of each of the fundamental parameters is discussed in this chapter.

The Drive Mode [ tyP], maximum frequency [PH ], and motor tone

selection [CPS] (See Chapter 12) cannot be adjusted during operation. Stop the drive before attempting to adjust these parameters.

TOSHIBA

Do not touch any of the terminal blocks or any of the circuitry inside the drive while the "CHARGE" LED Indicator is illuminated. An electrical charge is maintained on the capacitor and other electrical components

while this lamp is lit. Treat this condition with respect.

Not all motors can be driven to speeds above the base frequency (50 HZ or 60 HZ) for which they are designed. The variable speed range should be

limited to a safe operating range, since any general purpose motor that can be driven by the inverter is actually designed for constant speed operation. At operation above 60 HZ with a general purpose motor expect

limits on bearing life, mechanical strength, vibration, noise, and other motor design variables to affect operation. In general, only apply the

inverter within the guidelines shown in Table 9-1. Consult the motor manufacturer for recommendations for motor operation beyond these guidelines.

This sectioa of the manual describes the functions which the control terminals can perform. These terminals are used to send output signals about the condition in which the drive is operating, and to accept remote signals for automatic

operation. The methods of disabling and enabling many different features of the

inverter are also described. The methods for assigning and programming the control terminals are discussed, and examples are given of uses for the control terminals. The terminals, functions and parameters discussed in this chapter are shown below.

10.2 Frequency Setting Commands [F HOdJ

While in the drive mode, the frequency that the drive sends to the motor may be

changed with the or key. Many varieties of remote control signals may

also determine the running frequency of the motor. These Include potentiometers,

4-20 mAOC signals, 0-5 VDC signals, 0-10 VDC signals, and similar control

signals. Limitations can be placed on frequency setting and changing signals as

shown in Table 10-2.

10.3 Parameter Setting Disable Function [PnOd]

The drive parameters can be changed as explained In other chapters, but these parameters can only be changed if the Paraaeter Setting Disable Selection is enabled. In Table 10-3. This parameter can potentially be used for Increased

drive security. Once customized parameter settings are programmed and the

Parameter Setting Disable Function Is disabled none of the parameters may be

revised. Including all parameters still set at the factory default settings. Parameters can still be viewed by scrolling through the parameter tables.

When the assigned frequency Is reached during operation, the reached signal Is enabled at the output terminal RCH (UL) and LOW (LL). The output signal Is an

"open collector output" (24 VDC, 50 mADC, maximum). The control side receives

the signals from a relay, programmable controller with 24 VDC Input, or similar

Input device.

The "speed reached< signal connection" example using a relay Is shown In Figure

10.1. The "speed reached signal connection" example using a programmable controller Is shown In Figure 10.2. Toshiba strongly recommends the use of a surge absorption device (SA) around the coll of external output relays.

The "speed reached" signal does not have a hysteresis so the reached signal may cycle ON and OFF If the output frequency fluctuates near the reached frequency. In this case adjust the speed reached detection with

the [i~ f~ CH] function. See Section 10.7.2 In this chapter.

10.6 Low Speed Signal Output and Speed Reached Signal Output [LF, L F HL, Fr C H, rCH, rrCH]

These functions allow the drive to signal when certain output frequencies, parameters, or conditions have been reached or exceeded. When the output frequency reaches the preset low speed during operation and when the output frequency reaches the set frequency, the "reached" signal will enabled.

10.6.1 Low Speed Signal Output Frequency [LfJ and Speed Reached Logic Signal ILFHL]

The low speed signal output frequency [/. f ] can be set between 0 Hz and the maximum frequency. The signal output can also be selected logically. Implement

this feature with the parameter [ LFHL].

This [LFHL] signal is an open collector transistor used to send a signal to a remote device, defining the status of low speed, as shown below.

10.7 Frequency Setting via Remote Control Signals

This portion of the manual describes how to run the drive at various user assigned frequencies, which are determined by the use of external control

signals. The touchpad is not used for this operation, other than the initial

assignment of values and programming instructions.

After this programming is completed the drive may be run automatically. It may be desirable, from a security standpoint, to disable the touchpad when programming is completed, so that custom parameters and programming cannot be

changed or revised. See this chapter for details. (Parameters icnod],

[F n 0 d], and [Pfl 0 d]).

The output frequency fs controlled externally using terminals PP, RR, IV, and CC on the control circuit terminal blocks shown in Figure 10.4.

10.7.1 Types of Frequency Setting Signals

The frequency setting signals are changed using Jumpers J1 and JZ on the control printed circuit board. The juniper positions, combinations of parameters, and the function of these parameters is shown in Tables 10-9A, B, and C. The physical location of jumpers J1 and J2 (located inside each drive) is shown in Chapter 6.
