Safety Precautions

 Confirmations upon Delivery

• Never install an Inverter that is damaged or missing components.

Doing so can result in injury.

 Installation

• Always hold the case when carrying the Inverter.

If the Inverter is held by the front cover, the main body of the Inverter may fall, possibly resulting in injury.

• Attach the Inverter to a metal or other noncombustible material.

Fire can result if the Inverter is attached to a combustible material.

• Install a cooling fan or other cooling device when installing more than one Inverter in the same enclosure so that the temperature of the air entering the Inverters is below 45°C.

Overheating can result in fires or other accidents.

CAUTION

 Wiring

• Always turn OFF the input power supply before wiring terminals.

• Wiring must be performed by an authorized person qualified in electrical work.

• Be sure to ground the ground terminal. (200 V Class: Ground to 100 Ω or less, 400 V Class:

• Always check the operation of any emergency stop circuits after they are wired.

• Never touch the output terminals directly with your hands or allow the output lines to come into con-

Failure to observe this warning may result in injury.

function input terminal constant is set.

Failure to observe this warning may result in injury.

CAUTION

• Check to be sure that the voltage of the main AC power supply satisfies the rated voltage of the Inverter.

Injury or fire can occur if the voltage is not correct.

• Do not perform voltage withstand tests on the Inverter.

Otherwise, semiconductor elements and other devices can be damaged.

• Connect braking resistors, Braking Resistor Units, and Braking Units as shown in the I/O wiring examples.

Otherwise, a fire can occur and the Inverter, braking resistors, Braking Resistor Units, and Braking Units can be damaged.

iii

• Tighten all terminal screws to the specified tightening torque.

Otherwise, a fire may occur.

• Do not connect AC power to output terminals U, V, and W.

The interior parts of the Inverter will be damaged if voltage is applied to the output terminals.

• Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits.

The Inverter can be damaged or interior parts burnt if these devices are connected.

• Do not connect magnetic contactors to the output circuits.

If a load is connected while the Inverter is operating, surge current will cause the overcurrent protection circuit inside the Inverter to operate.

 Setting User Constants

• Disconnect the load (machine, device) from the motor before performing rotational autotuning.

The motor may turn, possibly resulting in injury or damage to equipment. Also, motor constants cannot be correctly set with the motor attached to a load.

• Stay clear of the motor during rotational autotuning.

The motor repeats running and stopping until autotuning has been completed, possibly resulting in injury.

• In stationary autotuning 1, when the motor is first operated in the drive mode after tuning, the remaining motor constants E2-02 (Motor rated slip) and E2-03 (Motor no-load current) are set automatically. To perform an operation immediately after stationary autotuning 1, use the following procedure under the recommended conditions.

(1) Check the values of E2-02 and E2-03 in verify mode or advanced programming mode. (2) Run the motor once in drive mode under the following conditions.

• The Inverter and the motor are connected.

• The motor shaft is not locked with a mechanical brake or other stopping mechanism (or function).

• A motor-load ratio of 30% or less is maintained.

• A speed of 30% or more of the base frequency set at E1-06 (default = highest frequency) is maintained at a constant speed for one second or more.

(3) After stopping the motor, check the values of E2-02 and E2-03 again in verify mode or advanced program-

ming mode. If the values of E2-02 and E2-03 differ from the ones before the first operation was carried out, the settings have been successfully completed. Next, check if the values are suitable or not.

If the values of E2-02 and E2-03 differed greatly from the reference data of the motor in the test report or the instruction manual (TOE-S616-60.1), hunting, motor vibrations, insufficient motor torque, or an overcurrent may occur because the motor is operated although the aforementioned conditions have not been fulfilled after stationary autotuning 1. For elevators, failure to observe this caution may result in the cage falling or injury. If so, perform stationary autotuning 1 again and run the motor using the aforementioned procedure under the recommended conditions or perform stationary autotuning 2 or rotational autotuning. Usually the standard setting for E2-02 is 1 Hz to 3 Hz, and that for E2-03 is 30% to 65% of the rated current for a generalpurpose motor. Generally, the larger the motor capacity is, the smaller the rated slip and the ratio of the no-load current to the rated current become. Use the data given in Factory Settings that Change with the Inverter Capacity (o2-04) of Chap- ter 5 User Constants as a reference.

CAUTION

 Trial Operation

WARNING

• Check to be sure that the front cover is attached before turning ON the power supply.

An electric shock may occur.

• Do not come close to the machine when the fault reset function is used. If the alarmed is cleared, the machine may start moving suddenly.

Also, design the machine so that human safety is ensured even when it is restarted. Injury may occur.

• Provide a separate emergency stop switch; the Digital Operator STOP Key is valid only when its function is set.

Injury may occur.

WARNING

• Reset alarms only after confirming that the RUN signal is OFF.

Injury may occur.

CAUTION

• Don't touch the radiation fins (heatsink), braking resistor, or Braking Resistor Unit. These can become very hot.

Otherwise, a burn injury may occur.

• Be sure that the motor and machine is within the applicable ranges before starting operation.

Otherwise, an injury may occur.

• Provide a separate holding brake if necessary. Always construct the external sequence to confirm that the holding brake is activated in the event of an emergency, a power failure, or an abnormality in the Inverter.

Failure to observe this caution can result in injury.

• If using an Inverter with an elevator, take safety measures on the elevator to prevent the elevator from dropping.

Failure to observe this caution can result in injury.

• Don't check signals while the Inverter is running.

Otherwise, the equipment may be damaged.

• Be careful when changing Inverter settings. The Inverter is factory set to suitable settings. For the Inverters in the 400 V class of 55 kW or more, however, select the correct power supply voltage jumper according to the input voltage.

Otherwise, the equipment may be damaged.

 Maintenance and Inspection

• Do not touch the Inverter terminals. Some of the terminals carry high voltages and are extremely dangerous.

Doing so can result in electric shock.

• Always have the protective cover in place when power is being supplied to the Inverter. When attaching the cover, always turn OFF power to the Inverter through the MCCB.

Doing so can result in electric shock.

• After turning OFF the main circuit power supply, wait until the CHARGE indicator light goes out before performing maintenance or inspections.

The capacitor will remain charged and is dangerous.

• Maintenance, inspection, and replacement of parts must be performed only by authorized personnel.

Remove all metal objects, such as watches and rings, before starting work. Always use grounded tools. Failure to heed these warning can result in electric shock.

• For 400-V class Inverters of 55 kW to 300 kW with SPEC: E or later, take safety measures such as the installation of an emergency-stop switch before adjusting constants.

Failure to do so may result in injury caused by the motor accidentally rotating during stationary autotuning performed by the Inverter when the constants are adjusted.

• Provide a separate holding brake if necessary.

Always make any adjustments other than those involving the operation of the Inverter with the holding brake released. Failure to observe this caution may result in injury.

• If using an Inverter with an elevator, take safety measures on the elevator to prevent the elevator from dropping.

Failure to observe this caution can result in injury.

WARNING

 Other

CAUTION

• A CMOS IC is used in the control board. Handle the control board and CMOS IC carefully.

The CMOS IC can be destroyed by static electricity if touched directly.

• Do not change the wiring, or remove connectors or the Digital Operator, during operation.

Doing so can result in personal injury.

WARNING

• Do not attempt to modify or alter the Inverter.

Doing so can result in electrical shock or injury.

CAUTION

Confirmations upon Delivery

 Checks

Check the following items as soon as the Inverter is delivered.

Table 1.2 Checks

Item Method

Has the correct model of Inverter been delivered?

Check the model number on the nameplate on the side of the Inverter.

Confirmations upon Delivery

Is the Inverter damaged in any way?

Are any screws or other components loose?

Inspect the entire exterior of the Inverter to see if there are any scratches or other damage resulting from shipping.

Use a screwdriver or other tools to check for tightness.

If you find any irregularities in the above items, contact the agency from which you purchased the Inverter or your Yaskawa representative immediately.

 Nameplate Information

There is a nameplate attached to the side of each Inverter. The nameplate shows the model number, specifications, lot number, serial number, and other information on the Inverter.

Fig 1.3 Inverter Specifications

Open Chassis Type (IEC IP00)

Protected so that parts of the human body cannot reach electrically charged parts from the front when the Inverter is mounted in a control panel.

Enclosed Wall-mounted Type [IEC IP20, NEMA 1 (Type 1)]

The Inverter is structured so that the Inverter is shielded from the exterior, and can thus be mounted to the interior wall of a standard building (not necessarily enclosed in a control panel). The protective structure conforms to the standards of NEMA 1 (Type 1) in the USA. The protective covers (see Fig. 1.4) are required for an IEC IP20 or NEMA 1 (Type 1) protective structure.

To enhance the reliability of operation, the Inverter should be installed in an environment free from extreme temperature increases. If the Inverter is installed in an enclosed environment, such as a box, use a cooling fan or air conditioner to maintain the internal air temperature below 45°C.

 Protecting the Inverter from Foreign Matter

Place a cover over the Inverter during installation to shield it from metal powder produced by drilling.

Always remove the cover from the Inverter after completing installation. Otherwise, ventilation will be reduced, causing the Inverter to overheat.

IMPORTANT

1. Control circuit terminals are arranged as shown below.

2. The output current capacity of the +V and −V terminals are 20 mA. Do not short-circuit between the +V, −V, and AC terminals. Doing so may result in a malfunction or a breakdown of the Inverter.

3. Disable the stall prevention during deceleration (set constant L3-04 to 0) when using a Braking Resistor Unit. If this user constant is not changed to disable stall prevention, the system may not stop during deceleration.

4. Main circuit terminals are indicated with double circles and control circuit terminals are indicated with single circles.

5. The wiring for a motor with a cooling fan is not required for self-cooling motors.

6. PG circuit wiring (i.e., wiring to the PG-B2 Board) is not required for control without a PG.

7. Sequence input signals S1 to S12 are labeled for sequence connections (0 V common and sinking mode) for no-voltage contacts or NPN transistors. These are the default settings. For PNP transistor sequence connections (+24V common and sourcing mode) or to provide a 24-V external power supply, refer to Table 2.13.

8. The multi-function analog output is a dedicated meter output for an analog frequency meter, ammeter, voltmeter, wattmeter, etc. Do not use this output for feedback control or for any other control purpose.

9. DC reactors to improve the input power factor are built into 200 V Class Inverters for 18.5 to 110 kW and 400 V Class Inverters for 18.5 to 300 kW. A DC reactor is thus an option only for Inverters for 15 kW or less.

10.Set constant L8-01 to 1 when using a breaking resistor (model ERF). When using a Braking Resistor Unit,

a shutoff sequence for the power supply must be made using a thermal relay trip.

11.The minimum permissible load of a multi-function contact output and an error contact output is 10 mA. Use

a multi-function open-collector output for a load less than 10 mA.

12.Do not ground nor connect the AC terminal on the control circuit to the unit. Doing so may result in a mal-

function or a breakdown of the Inverter.

13.If turning off the power only for the main circuit but leaving the power ON for the control circuit, use a sep-

arate power supply for the control circuit and a specially designed Inverter, which are sold as options.

 Wiring the Main Circuits

This section describes wiring connections for the main circuit inputs and outputs.

Wiring Main Circuit Inputs

Observe the following precautions for wiring the main circuit power supply inputs.

Installing a Molded-case Circuit Breaker

Always connect the power input terminals (R, S, and T) and power supply via a molded-case circuit breaker (MCCB) suitable for the Inverter.

• Choose an MCCB with a capacity of 1.5 to 2 times the Inverter's rated current.

• For the MCCB's time characteristics, be sure to consider the Inverter's overload protection (one minute at

150% of the rated output current).

• If the same MCCB is to be used for more than one Inverter, or other devices, set up a sequence so that the

power supply will be turned OFF by a fault output, as shown in Fig 2.6.

Power supply

20P4 to 2030: 3-phase, 200 to 240 VAC, 50/60 Hz

2037 to 2110: 3-phase, 200 to 230 VAC, 50/60 Hz

40P4 to 4300: 3-phase, 380 to 460 VAC, 50/60 Hz

* For 400 V Class Inverters, connect a 400/200 V transformer.

Fig 2.6 MCCB Installation

Inverter

R/L1

S/L2

T/L3

Fault output (NC)

Installing a Ground Fault Interrupter

Inverter outputs use high-speed switching, so high-frequency leakage current is generated. At the Inverter primary side, use a ground fault interrupter for Inverters with a countermeasure against high frequency to detect only the leakage current in the frequency range that is hazardous to humans and to ignore high-frequency leakage current. Use one or several ground fault interrupters with a total cumulative sensitivity amperage of at least 30 mA per Inverter.

2-16

Using a ground fault interrupter without a countermeasure against high frequency may result in a malfunction caused by high-frequency leakage current. If a ground fault interrupter without a countermeasure malfunctions, replace it with a ground fault interrupter with a countermeasure against high frequency or reduce the carrier frequency of the Inverter. Alternatively, use one or several ground fault interrupters with a total cumulative sensitivity amperage of at least 200 mA per Inverter.

Wiring Main Circuit Terminals

Installing a Magnetic Contactor

If the power supply for the main circuit is to be shut off during a sequence, a magnetic contactor can be used.

When a magnetic contactor is installed on the primary side of the main circuit to forcibly stop the Inverter, however, the regenerative braking does not work and the Inverter will coast to a stop.

• The Inverter can be started and stopped by opening and closing the magnetic contactor on the primary side.

Frequently opening and closing the magnetic contactor, however, may cause the Inverter to break down. Start and stop the Inverter at most once every 30 minutes.

• When the Inverter is operated with the Digital Operator, automatic operation cannot be performed after

recovery from a power interruption.

• If the Braking Resistor Unit is used, program the sequence so that the magnetic contactor is turned OFF by

the contact of the Unit's thermal overload relay.

Connecting Input Power Supply to the Terminal Block

Input power supply can be connected to any terminal R, S or T on the terminal block; the phase sequence of input power supply is irrelevant to the phase sequence.

Installing an AC Reactor or DC Reactor

If the Inverter is connected to a large-capacity power transformer (600 kW or more) or the phase advancing capacitor is switched, an excessive peak current may flow through the input power circuit, causing the converter unit to break down.

To prevent this, install an optional AC Reactor on the input side of the Inverter or a DC reactor to the DC reactor connection terminals.

This also improves the power factor on the power supply side.

Installing a Surge Absorber

Always use a surge absorber or diode for inductive loads near the Inverter. These inductive loads include magnetic contactors, electromagnetic relays, solenoid valves, solenoids, and magnetic brakes.

Installing a Noise Filter on Power Supply Side

Install a noise filter to eliminate noise transmitted between the power line and the Inverter.

• Correct Noise Filter Installation

Wiring the Output Side of Main Circuit

Observe the following precautions when wiring the main output circuits.

Connecting the Inverter and Motor

Connect output terminals U, V, and W to motor lead wires U, V, and W, respectively.

Check that the motor rotates forward with the Forward Run Command. Switch over any two of the output terminals to each other and reconnect if the motor rotates in reverse with the Forward Run Command.

Never Connect a Power Supply to Output Terminals

Never connect a power supply to output terminals U, V, and W. If voltage is applied to the output terminals, the internal circuits of the Inverter will be damaged.

Never Short or Ground Output Terminals

If the output terminals are touched with bare hands or the output wires come into contact with the Inverter casing, an electric shock or grounding will occur. This is extremely hazardous. Do not short the output wires.

Do Not Use a Phase Advancing Capacitor or Noise Filter

Never connect a phase advancing capacitor or LC/RC noise filter to an output circuit. The high-frequency components of the Inverter output may result in overheating or damage to these part or may result in damage to the Inverter or cause other parts to burn.

Do Not Use a Magnetic Contactor

Never connect a magnetic contactor between the Inverter and motor and turn it ON or OFF during operation. If the magnetic contactor is turned ON while the Inverter is operating, a large inrush current will be created and the overcurrent protection in the Inverter will operate.

2-18

When using a magnetic contactor to switch to a commercial power supply, stop the Inverter and motor before operating the magnetic contactor. Use the speed search function if the magnetic contactor is operated during

Wiring Main Circuit Terminals

operation. If measures for momentary power interrupts are required, use a delayed release the magnetic contactor.

Installing a Thermal Overload Relay

This Inverter has an electronic thermal protection function to protect the motor from overheating. If, however, more than one motor is operated with one Inverter or a multi-polar motor is used, always install a thermal relay (THR) between the Inverter and the motor and set L1-01 to 0 (no motor protection). The sequence should be designed so that the contacts of the thermal overload relay turn OFF the magnetic contactor on the main circuit inputs.

Installing a Noise Filter on Output Side

Connect a noise filter to the output side of the Inverter to reduce radio noise and inductive noise.

Power supply

Inductive Noise: Electromagnetic induction generates noise on the signal line, causing the controller to malfunction.

Radio Noise: Electromagnetic waves from the Inverter and cables cause the broadcasting radio receiver to make

noise.

Countermeasures Against Inductive Noise

As described previously, a noise filter can be used to prevent inductive noise from being generated on the output side. Alternatively, cables can be routed through a grounded metal pipe to prevent inductive noise. Keeping the metal pipe at least 30 cm away from the signal line considerably reduces inductive noise.

Countermeasures Against Radio Interference

Radio noise is generated from the Inverter as well as from the input and output lines. To reduce radio noise, install noise filters on both input and output sides, and also install the Inverter in a totally enclosed steel box.

The cable between the Inverter and the motor should be as short as possible.

Cable Length between Inverter and Motor

If the cable between the Inverter and the motor is long, the high-frequency leakage current will increase, causing the Inverter output current to increase as well. This may affect peripheral devices. To prevent this, adjust the carrier frequency (set in C6-02) as shown in Table 2.6. (For details, refer to Chapter 5 User Constants.)

Observe the following precautions when wiring the ground line.

• Always use the ground terminal of the 200 V Inverter with a ground resistance of less than 100 Ω and that

of the 400 V Inverter with a ground resistance of less than 10 Ω.

• Do not share the ground wire with other devices, such as welding machines or power tools.

• Always use a ground wire that complies with technical standards on electrical equipment and minimize the

length of the ground wire. Leakage current flows through the Inverter. Therefore, if the distance between the ground electrode and the ground terminal is too long, potential on the ground terminal of the Inverter will become unstable.

• When using more than one Inverter, be careful not to loop the ground wire.

Connecting the Braking Resistor (ERF)

A Braking Resistor that mounts to the Inverter can be used with 200 V and 400 V Class Inverters with outputs from 0.4 to 3.7 kW.

Connect the braking resistor as shown in Fig 2.13.

Table 2.7

L3-04 (Stall prevention selection during deceleration) (Select either one of them.)

Inverter

Fig 2.13 Connecting the Braking Resistor

The braking resistor connection terminals are B1 and B2. Do not connect to any other terminals. Connecting to any terminals other than B1 or B2 can cause the resistor to overheat, resulting in damage to the equipment.

Connecting the Braking Resistor Unit (LKEB) and Braking Unit (CDBR)

Use the following settings when using a Braking Resistor Unit. Refer to Wiring Examples on page 10-20 for connection methods for a Braking Resistor Unit.

A Braking Resistor that mounts to the Inverter can also be used with Inverters with outputs from 0.4 to

3.7 kW.

Table 2.8

L3-04 (Stall prevention selection during deceleration) (Select either one of them.)

0 (Disables stall prevention function)

3 (Enables stall prevention function with braking resistor)

L8-01 is used when a braking resistor without thermal overload relay trip contacts (ERF type mounted to Inverter) is connected.

The Braking Resistor Unit cannot be used and the deceleration time cannot be shortened by the Inverter if L304 is set to 1 (i.e., if stall prevention is enabled for deceleration).

Wiring Control Circuit Terminals

 Wire Sizes and Closed-loop Connectors

For remote operation using analog signals, keep the control line length between the Digital Operator or operation signals and the Inverter to 50 m or less, and separate the lines from high-power lines (main circuits or relay sequence circuits) to reduce induction from peripheral devices.

When setting frequencies from an external frequency setter (and not from a Digital Operator), use shielded twisted-pair wires and ground the shield to terminal E (G), as shown in the following diagram.

 Control Circuit Wiring Precautions

Observe the following precautions when wiring control circuits.

• Separate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, B1, B2, U/T1, V/T2,

W/T3, , 1, 2, and 3) and other high-power lines.

• Separate wiring for control circuit terminals MA, MB, MC, M1, and M2 (contact outputs) from wiring to

other control circuit terminals.

• Use shielded twisted-pair cables for control circuits to prevent operating faults. Process cable ends as

shown in Fig 2.20.

• Connect the shield wire to terminal E (G).

• Insulate the shield with tape to prevent contact with other signal lines and equipment.

• Use a class 2 power supply (UL standard) when connecting to the control terminals.

 Installation

Before mounting an option board, remove the terminal cover and be sure that the charge indicator inside the Inverter is not lit. After confirming that the charge indicator is not lit, remove the Digital Operator and front cover and then mount the option board.

The side of the front cover of the Inverter for 200/400 V Class 0.4 to 3.7 kW can be cut out as described in Fig

2.22 to make wiring of the option board easy. If the side of the front cover is cut out, the protective structure will be open chassis (IEC IP00).

Refer to documentation provided with the option board for actual mounting instructions for option slots A, C, and D.

 Preventing C and D Option Board Connectors from Rising

After installing an option board into slot C or D, insert an option clip to prevent the side with the connector from rising. The option clip can be easily removed by holding onto the protruding portion of the clip and pulling it out.

Remove the option clip before installing an option board into slot C or D. The option board can not be installed completely and may not function properly if it is installed with the option clip attached.

Wiring Method and Precautions

The wiring method is the same as the one used for straight solderless terminals. Refer to page 2-23. Observe the following precautions when wiring.

• Separate the control signal lines for the PG Speed Control Board from main circuit lines and power lines.

• Connect the shield when connecting to a PG. The shield must be connected to prevent operational errors

caused by noise. Also, do not use any lines that are more than 100 m long. Refer to Fig 2.20 for details on connecting the shield.

• Connect the shield to the shield terminal (E).

• Do not solder the ends of wires. Doing so may cause contact faults.

• When not using straight solderless terminals, strip the wires to a length of approximately 5.5 mm.

Installing and Wiring Option Boards

 Selecting the Number of PG (Encoder) Pulses

The setting for the number of PG pulses depends on the model of PG Speed Control Board being used. Set the correct number for your model.

 Verify Mode

Verify mode is used to display any constants that have been changed from their default settings in a programming mode or by autotuning. “None” will be displayed if no settings have been changed.

Of the environment mode settings, only A1-02 will be displayed if it has been changed. Other environment modes settings will not be displayed even if they have been changed from their default settings.

Even in verify mode, the same procedures can be used to change settings as are used in the programming modes. Use the Increment, Decrement, and Shift/RESET Keys to change the frequency. The user constant will be written and the monitor display will be returned to when the DATA/ENTER Key is pressed after changing the setting.

Example Operations

An example of key operations is given below for when the following settings have been changed from their default settings: b1-01 (Reference Selection), C1-01 (Acceleration Time 1), E1-01 (Input Voltage Setting), and E2-01 (Motor Rated Current).

 Autotuning Mode

Autotuning automatically tunes and sets the required motor constants when operating in the vector control methods. Always perform autotuning before starting operation.

When V/f control has been selected, stationary autotuning for only line-to-line resistance can be selected.

When the motor cannot be disconnected from the load, perform stationary autotuning. Contact your Yaskawa representatives to set motor constants by calculation.

The Inverter's autotuning function automatically determines the motor constants, while a servo system's autotuning function determines the size of a load, so these autotuning functions are fundamentally different. The default setting of the Inverter is for open-loop vector 1 control.

Example of Operation

Set the motor output power (in kW), rated voltage, rated current, rated frequency, rated speed, and number of poles specified on the nameplate on the motor and then press the RUN Key. The motor is automatically run and the motor constants measured based on these settings and autotuning will be set.

Always set the above items. Autotuning cannot be started otherwise, e.g., it cannot be started from the motor rated voltage display.

The following example shows autotuning for open-loop vector control while operating the motor without switching to motor 2.

Trial Operation Procedures

The procedure for the trial operate is described in order in this section.

 Setting the Power Supply Voltage Jumper (400 V Class Inverters of 55 kW

or Higher)

Set the power supply voltage jumper after setting E1-01 (Input Voltage Setting) for 400 V Class Inverters

of 55 kW or higher. Insert the jumper into the power tap nearest to the actual power supply

voltage. If the wrong jumper is selected, the Inverter may be damaged.

The jumper is factory-set to 440 V when shipped. If the power supply voltage is not 440 V, use the

following procedure to change the setting.

1. Turn OFF the power supply and wait for at least 5 minutes.

2. Confirm that the CHARGE indicator has gone out.

3. Remove the terminal cover.

4. Insert the jumper at the position for the voltage supplied to the Inverter (see Fig 4.2).

5. Return the terminal cover to its original position.

• Set either one of the fixed patterns (0 to E) in E1-03 (V/f Pattern Selection) or set F in E1-03 to specify a

user-set pattern as required for the motor and load characteristics in E1-04 to E1-13 in advanced programming mode.

Simple operation of a general-purpose motor at 50 Hz:

E1-03 = 0

Simple operation of a general-purpose motor at 60 Hz:

E1-03 = F (default) or 1 If E1-03 = F, the default setting in the user setting from E1-04 to E1-13 are for 60 Hz

4-8

• Perform stationary autotuning for the line-to-line resistance only if the motor cable is 50 m or longer for

the actual installation or the load is heavy enough to produce stalling. Refer to the following section on Autotuning for details on stationary autotuning.

V/f Control with PG (A1-02=1)

• Set either one of the fixed patterns (0 to E) in E1-03 (V/f Pattern Selection) or set F in E1-03 to specify a

user-set pattern as required for the motor and load characteristics in E1-04 to E1-13 in advanced programming mode.

Simple operation of a general-purpose motor at 50 Hz:

E1-03 = 0

Simple operation of a general-purpose motor at 60 Hz:

E1-03 = F (default) or 1 If E1-03 = F, the default setting in the user setting from

E1-04 to E1-13 are for 60 Hz

• Set the number of motor poles in E2-04 (Number of Motor Poles)

• Set the number of rotations per pulse in F1-01 (PG Constant). If there is a reduction gear between the

motor and PG, set the reduction ratio in F1-12 and F1-13 in advanced programming mode.

Trial Operation Procedures

• Perform stationary autotuning for the line-to-line resistance only if the motor cable is 50 m or longer for

the actual installation or the load is heavy enough to produce stalling. Refer to the following section on Autotuning for details on stationary autotuning.

Open-loop Vector 1 Control (A1-02 = 2)

Perform autotuning. If the motor can be operated, perform rotational autotuning. If the motor cannot be operated, perform stationary autotuning 1 or 2. Refer to the following section on Autotuning for details on autotun- ing.

Flux Vector Control (A1-02 = 3)

Open-loop Vector 2 Control (A1-02 = 4)

 Autotuning

Use the following procedure to perform autotuning to automatically set motor constants when using the vector control method, when the cable length is long, etc.

If the control method was changed after autotuning, be sure to perform autotuning again.

One of the following four autotuning modes can be set.

• Rotational autotuning

• Stationary autotuning 1

• Stationary autotuning for line-to-line resistance only

• Stationary autotuning 2

 Precautions Before Using Autotuning

Read the following precautions before using autotuning.

• Autotuning the Inverter is fundamentally different from autotuning the servo system. Inverter autotuning

automatically adjusts parameters according to detected motor constants, whereas servo system autotuning adjusts parameters according to the detected size of the load.

• When speed or torque precision is required at high speeds (i.e., 90% of the rated speed or higher), use a

motor with a rated voltage that is 20 V less than the input power supply voltage of the Inverter for 200Vclass Inverters and 40 V less for 400V-class Inverters. If the rated voltage of the motor is the same as the input power supply voltage, the voltage output from the Inverter will be unstable at high speeds and sufficient performance will not be possible.

• Use stationary autotuning 1 or 2 whenever performing autotuning for a motor that is connected to a load.

• Use rotational autotuning whenever performing autotuning for a motor that has fixed output characteris-

tics, when high precision is required, or for a motor that is not connected to a load.

• If rotational autotuning is performed for a motor connected to a load, the motor constants will not be found

accurately and the motor may exhibit abnormal operation. Never perform rotational autotuning for a motor connected to a load.
