Warnings and Cautions

WARNING

This Section provides warnings and cautions pertinent to this product, that if not heeded, may result in personal injury, fatality, or equipment damage. Yaskawa is not responsible for consequences of ignoring these instructions.

YASKAWA manufactures component parts that can be used in a wide variety of industrial applications. The selection and application of YASKAWA products remain the responsibility of the equipment designer or end user. YASKAWA accepts no responsibility for the way its products are incorporated into the final system design. Under no circumstances should any YASKAWA product be incorporated into any product or design as the exclusive or sole safety control. Without exception, all controls should be designed to detect faults dynamically and fail safely under all circumstances. All products designed to incorporate a component part manufactured by YASKAWA must be supplied to the end user with appropriate warnings and instructions as to that part’s safe use and operation. Any warnings provided by YASKAWA must be promptly provided to the end user. YASKAWA offers an express warranty only as to the quality of its products in conforming to standards and specifications published in the YASKAWA manual. NO OTHER WARRANTY, EXPRESS OR IMPLIED, IS OFFERED. YASKAWA assumes no liability for any personal injury, property damage, losses, or claims arising from misapplication of its products.

• Read and understand this manual before installing, operating, or servicing this Drive. All warnings, cautions, and

instructions must be followed. All activity must be performed by qualified personnel. The Drive must be installed according to this manual and local codes.

• Do not connect or disconnect wiring while the power is on. Do not remove covers or touch circuit boards while the power is

on. Do not remove or insert the digital operator while power is on.

• Before servicing, disconnect all power to the equipment. The internal capacitor remains charged even after the power supply

is turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50Vdc. To prevent electric shock, wait at least five minutes after all indicators are OFF and measure DC bus voltage level to confirm safe level.

• Do not perform a withstand voltage test on any part of the unit. This equipment uses sensitive devices and may be damaged

by high voltage.

• The Drive is suitable for circuits capable of delivering not more than 100,000 RMS symmetrical Amperes, 240Vac

maximum (200-240V Class) and 480Vac maximum (380-480V Class). Install adequate branch circuit short circuit protection per applicable codes. Failure to do so may result in equipment damage and/or personal injury. Refer to Appendix E for further details.

• Do not connect unapproved LC or RC interference suppression filters, capacitors, or overvoltage protection devices to the

output of the Drive. These devices may generate peak currents that exceed Drive specifications.

• To avoid unnecessary fault displays caused by contactors or output switches placed between Drive and motor, auxil-

iary contacts must be properly integrated into the control logic circuit.

• YASKAWA is not responsible for any modification of the product made by the user; doing so will void the warranty.

This product must not be modified.

• Verify that the rated voltage of the Drive matches the voltage of the incoming power supply before applying power.

• To meet CE directives, proper line filters and proper installation are required.

• Some drawings in this manual may be shown with protective covers or shields removed, to describe details. These

must be replaced before operation.

• Observe electrostatic discharge procedures when handling circuit boards to prevent ESD damage.

• The equipment may start unexpectedly upon application of power. Clear all personnel from the Drive, motor, and

machine area before applying power. Secure covers, couplings, shaft keys, and machine loads before energizing the Drive.

• Please do not connect or operate any equipment with visible damage or missing parts. The operating company is

responsible for any injuries or equipment damage resulting from failure to heed the warnings in this manual.

• In an environment where metal shavings, oil, water, or other foreign materials do not get into the Drive.

• In a location free from radioactive materials and combustible materials (e.g. wood).

• In a location free from harmful gases and liquids.

• In a location free from excessive vibration.

• In a location free from chlorides

• In a location away from direct sunlight.

1-10

 Controlling the Ambient Temperature

To enhance the reliability of operation, the Drive should be installed in an environment free from extreme temperature variation. If the Drive is installed in an enclosure, use a cooling fan or air conditioner to maintain the internal air temperature below 113°

F (45°C).

 Protecting the Drive from Foreign Matter

During Drive installation and project construction, it is possible to have foreign matter such as metal shavings or wire clippings fall inside the Drive. To prevent foreign matter from falling into the Drive, place a temporary cover over the Drive.

Always remove the temporary cover from the Drive before start-up. Otherwise, ventilation will be reduced, causing the Drive to overheat.

1. Control circuit terminals are arranged as shown below.

2. The output current capacity of the +V terminal is 20 mA.

3. Disable the stall prevention during deceleration (set parameter L3-04 to 0) when using a Braking Resistor Unit. If this user parameter 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-X2 Card) is not required for open-loop vector control.

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 toTable 2.13.

8. The master speed frequency reference can set to input either a voltage (terminal A1) or current (terminal A2) by changing the setting of parameter H3-13. The default setting is for a voltage reference input.

9. 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.

10.DC reactors to improve the input power factor built into 200-240 V Class Drives for 18.5 to 110 kW and 380-480 V Class Drives for 18.5 to 300 kW. A DC reactor is thus an option only for Drives for 15 kW or less.

11.Set parameter L8-01 to 1 when using a breaking resistor (ERF). When using a Braking Resistor Unit, a shutoff sequence for the power supply must be made using a thermal relay trip.

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

Wiring Main Circuit Inputs

Observe the following precautions for the main circuit power supply input.

Installing a Molded-case Circuit Breaker

Always connect the power input terminals (R/L1, S/L2, and T/L3) and power supply via a molded-case circuit breaker (MCCB) suitable for the Drive.

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

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

150% of the rated output current).

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

power supply will be turned OFF by a fault output, as shown in Fig 2.5.

Installing a Ground Fault Interrupter

Drive outputs use high-speed switching, so high-frequency leakage current is generated. Therefore, at the Drive primary side, use a ground fault interrupter to detect only the leakage current in the frequency range that is hazardous to humans and exclude high-frequency leakage current.

2-16

Fig 2.5 MCCB Installation

• For the special-purpose ground fault interrupter for Drives, choose a ground fault interrupter with a

sensitivity amperage of at least 30 mA per Drive.

• When using a general ground fault interrupter, choose a ground fault interrupter with a sensitivity

amperage of 200 mA or more per Drive and with an operating time of 0.1 s or more.

Noise filter

Drive

Other controllers

Use a special-purpose noise filter for Drives.

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 Drive, however, the regenerative braking does not work and the Drive will coast to a stop.

• The Drive 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 Drive to break down. Start and stop the Drive at most once every 30 minutes.

• When the Drive 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/L1, S/L2, or T/L3 on the terminal block; the phase sequence of input power supply is irrelevant to the phase sequence.

Installing an AC Reactor

If the Drive is connected to a large-capacity power transformer (600 kVa 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 Drive or a DC link choke to the DC link choke 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 Drive. 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 Drive.

Generalpurpose noise filter

Do not use general-purpose noise filters. Generalpurpose noise filter can not effectively suppress noise generated from the Drive.

Fig 2.7 Incorrect Power supply Noise Filter Installation

Wiring the Output Side of Main Circuit

Observe the following precautions when wiring the main output circuits.

Connecting the Drive and Motor

Connect output terminals U/T1, V/T2, and W/T3 to motor lead wires U/T1, V/T2, and W/T3, 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/T1, V/T2, and W/T3. If voltage is applied to the output terminals, the internal circuits of the Drive 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 Drive

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 Drive output may result in overheating or damage to these part or may result in damage to the Drive or cause other parts to burn.

Do Not Use an Electromagnetic Switch

Never connect an electromagnetic switch (MC) between the Drive and motor and turn it ON or OFF during operation. If the MC is turned ON while the Drive is operating, a large inrush current will be created and the overcurrent protection in the Drive will operate.

When using an MC to switch to a commercial power supply, stop the Drive and motor before operating the MC. Use the speed search function if the MC is operated during operation. If measures for momentary power interrupts are required, use a delayed release MC.

Installing a Thermal Overload Relay

This Drive has an electronic thermal protection function to protect the motor from overheating. If, however, more than one motor is operated with one Drive or a multi-pole motor is used, always install a thermal relay (THR) between the Drive 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 Drive to reduce radio noise and inductive noise.

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

Radio Noise: Electromagnetic waves from the Drive and cables cause the broadcasting radio receiver to make noise.

Fig 2.8 Installing a Noise Filter on the Output Side

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 (approximately 1 foot) away from the signal line considerably reduces inductive noise.

Steel box

Radio noise is generated from the Drive 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 Drive in a totally enclosed steel box.

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

Fig 2.10 Countermeasures Against Radio Interference

Cable Length between Drive and Motor

If the cable between the Drive and the motor is long, the high-frequency leakage current will increase, causing the Drive output current to increase as well. This may affect peripheral devices. To prevent this, adjust the carrier frequency (set in C6-01, C6-02) as shown in Table 2.6. (For details, refer to Chapter 3 User Parameters.)

Table 2.6 Cable Length between Drive and Motor

Cable length 50 m max. (164 ft) 100 m max. (328 ft) More than 100 m (> 328 ft)

Carrier frequency 15 kHz max. 10 kHz max. 5 kHz max.

Ground Wiring

Observe the following precautions when wiring the ground line.

• Always use the ground terminal of the 200-240 V Drive with a ground resistance of less than 100 Ω and

that of the 380-480 V Drive 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 Drive. Therefore, if the distance between the ground electrode and the ground terminal is too long, potential on the ground terminal of the Drive will become unstable.

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

Connecting the Braking Resistor (ERF)

A Braking Resistor that mounts to the Drive can be used with 200-240 V and 380-480 V Class Drives with outputs from 0.4 to 3.7 kW.

Connect the braking resistor as shown in Fig 2.12.

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

Use the following settings when using a Braking Resistor Unit. Refer to User Parameters on page 10-18 for connection methods for a Braking Resistor Unit.

A Braking Resistor that mounts to the Drive can also be used with Drives with outputs from 0.4 to 3.7 kW.

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

The Braking Resistor Unit cannot be used and the deceleration time cannot be shortened by the Drive if L3-04 is set to 1 (i.e., if stall prevention is enabled for deceleration).

 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 Drive to 50 m (164 ft) 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 reference (and not from a Digital Operator), used shielded twisted-pair wires and ground the shield to terminal E (G), as shown in the following diagram.

 Control Circuit Wiring Precautions

Shield sheath

Armor

Connect to shield sheath terminal at Drive (terminal E (G))

Insulate with tape

Do not connect here.

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, M2, M3, M4, M5, and M6 (contact

outputs) from wiring to other control circuit terminals.

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

cable ends as shown in Fig 2.17.

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

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

Fig 2.17 Processing the Ends of Twisted-pair Cables

 Control Circuit Wire Sizes

For remote operation, keep the length of the control wiring to 50m or less. Separate the control wiring from highpower lines (input power, motor leads or relay sequence circuits) to reduce noise induction from peripheral devices.

When setting speed commands from an external speed potentiometer, use shielded twisted-pair wires and ground the shield to terminal E(G), as shown above. Terminal numbers and wire sizes are shown in Table 2.9.

 Wiring Checks

Check all wiring after wiring has been completed. Do not perform a buzzer check on control circuits. Perform the following checks on the wiring.

• Is all wiring correct?

• Have any wire clippings, screws, or other foreign material been left?

• Are all screws tight?

• Are any wire ends contacting other terminals?

Use this mode to reference and set the minimum user parameters to operate the Drive (e.g., the operating environment of the Drive and Digital Operator).

Use this mode to read/set user parameters that have been changed from their factory-set values.

Use this mode when running a motor with unknown motor parameters in the vector control mode. The motor parameters are calculated and set automatically. This mode can also be used to measure only the motor line-to-line resistance.

* Always perform autotuning with the motor before operating using vector control. Autotuning mode will not be displayed during operation or when an

error has occurred. The default setting of the Drive is for open-loop vector control 1 (A1-02 = 2).

 Verify Mode

Verify mode is used to display any parameters 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 parameter 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).

Fig 3.6 Operations in Verify Mode

3-13

 Autotuning Mode

Autotuning automatically tunes and sets the required motor parameters when operating in the vector control modes. 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 parameters by calculation.

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

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 parameters 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.

 Autotuning

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

 Setting the Autotuning Mode

One of the following three autotuning modes can be set.

• Rotational autotuning

• Stationary autotuning

• Stationary autotuning for line-to-line resistance only

Always confirm the precautions before autotuning before performing autotuning.

Rotational Autotuning (T1-01 = 0)

Rotational autotuning is used only for open-vector control. Set T1-01 to 0, input the data from the nameplate, and then press the RUN Key on the Digital Operator. The Drive will stop the motor for approximately 1 minute and then set the required motor parameters automatically while operating the motor for approximately 1 minute.

Stationary Autotuning (T1-01 = 1)

Stationary autotuning is used for open-vector control or flux vector control. Set T1-01 to 1, input the data from the nameplate, and then press the RUN Key on the Digital Operator. The Drive will supply power to the stationary motor for approximately 1 minute and some of the motor parameters will be set automatically. The remaining motor parameters will be set automatically the first time operation is started in drive mode.

4-9

Stationary Autotuning for Line-to-Line Resistance Only (T1-01 = 2)

IMPORTANT

Stationary autotuning for line-to-line resistance only can be used in any control method. This is the only autotuning possible for V/f control and V/f control with PG modes.

Autotuning can be used to prevent control errors when the motor cable is long (50 m or longer) or the cable length has changed since installation or when the motor and Drive have different capacities.

Set T1-01 to 2 for open-loop vector control, and then press the RUN Key on the Digital Operator. The Drive will supply power to the stationary motor for approximately 20 seconds and the Motor Line-to-Line Resistance (E2-05) and cable resistance will be automatically measured.

 Precautions Before Using Autotuning

Read the following precautions before using autotuning.

• Autotuning the Drive is fundamentally different from autotuning the servo system. Drive autotuning auto-

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

• When speed precision 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 Drive for 200240V-class Drives and 40 V less for 380-480V-class Drives. If the rated voltage of the motor is the same as the input power supply voltage, the voltage output from the Drive will be unstable at high speeds and sufficient performance will not be possible.

• Use stationary autotuning 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 parameters will not be

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

• If the wiring between the Drive and motor changes by 50 m or more between autotuning and motor instal-

lation, perform stationary autotuning for line-to-line resistance only.

• If the motor cable is long (50 m or longer), perform stationary autotuning for line-to-line resistance only

even when using V/f control.

• The status of the multi-function inputs and multi-function outputs will be as shown in the following table

during autotuning. When performing autotuning with the motor connected to a load, be sure that the holding brake is not applied during autotuning, especially for conveyor systems or similar equipment.

• To cancel autotuning, always use the STOP Key on the Digital Operator.

1. Power will be supplied to the motor when stationary autotuning is performed even though the motor will not turn. Do not touch the motor until autotuning has been completed.

2. When performing stationary autotuning connected to a conveyor or other machine, ensure that the holding brake is not activated during autotuning.

Precautions for Rotational and Stationary Autotuning

Lower the base voltage based on Fig 4.4 to prevent saturation of the Drive’s output voltage when the rated voltage of the motor is higher than the voltage of the power supply to the Drive. Use the following procedure to perform autotuning.

1. Input the voltage of the input power supply to T1-03 (Motor rated voltage).

2. Input the results of the following formula to T1-05 (Motor base frequency):

(Base frequency from the motor’s nameplate × setting of T1-03)/(Rated voltage from motor’s nameplate)

3. Perform autotuning.

After completing autotuning, set E1-04 (Max. output frequency) to the base frequency from the motor’s nameplate.

Fig 4.4 Motor Base Frequency and Drive Input Voltage Setting

1. When speed precision is required at high speeds (i.e., 90% of the rated speed or higher), set T1-03 (Motor rated voltage) to the input power supply voltage × 0.9.

2. When operating at high speeds (i.e., 90% of the rated speed or higher), the output current will increase as the input power supply voltage is reduced. Be sure to provide sufficient margin in the Drive current.

Precautions after Rotational and Stationary Autotuning

If the maximum output frequency and base frequency are different, set the maximum output frequency (E1-

04) after autotuning.
