4. Wiring

WARNING • Only begin wiring after verifying that the power supply is turned OFF.


• Wiring should be performed only by qualified personnel.


• When wiring the emergency stop circuit, check the wiring thoroughly before operation.


• For 400 V class, make sure to ground the supply neutral.


CAUTION

• Verify that the Inverter rated voltage coincides with the AC power supply voltage.

Failure to observe this caution may result in personal injury or a fire.

• Do not perform a withstand voltage test on the

Inverter.

Performing withstand voltage tests may damage semiconductor elements.

• Always tighten terminal screws of the main circuit and the control circuits.

Failure to observe this caution may result in a malfunction, damage, or a fire.

• Never connect the AC main circuit power supply to output terminals U/T1, V/T2, W/T3, B1, B2, −, +1, or +2.

The Inverter will be damaged and the guarantee will be voided.

• Do not connect or disconnect wires or connectors while power is applied to the circuits.




• To store the constant with an ENTER command by communications, be sure to take measures for an

28

4. Wiring emergency stop by using the external terminals.

Delayed response may cause injury or damage the machine.

Wiring Instructions

1. Always connect the power supply for the main circuit inputs to the power input terminals R/L1, S/L2, and T/L3 (R/L1, S/L2 for singlephase power) via a molded-case circuit breaker (MCCB) or a fuse.

Never connect the power supply to terminals U/T1, V/T2, W/T3, B1,

B2, −, +1, or +2. The Inverter may be damaged.

For 200 V single-phase Inverters, always use terminals R/L1 and S/

L2. Never connect terminal T/L3.

Refer to page 239 for recommended peripheral devices.

Use a UL class RK5 fuse. For single-phase, 200-V Inverters of

075 kW or less, a 3-phase, 200-V power supply can also be connected.

2. If the wiring distance between Inverter and motor is long, reduce the

Inverter carrier frequency. For details, refer to Reducing Motor

Noise or Leakage Current (n080) on page 151. Control wiring must be less than 50 m (164 ft) in length and must be separated from power wiring. Use shielded twisted-pair cable when inputting the frequency signal externally.

3. For 400 V Class Inverters, always ground the supply neutral to conform to CE requirements.

4. Closed-loop connectors should be used when wiring to the main circuit terminals.

29

30

5. Voltage drop should be considered when determining the wire size.

Voltage drop can be calculated using the following equation:

Phase-to-phase voltage drop (V)

3 × wire resistance (Ω/km) × wiring distance (m) × current

(A) × 10 -3

Select a wire size so that voltage drop will be less than 2% of the normal rated voltage. Increase the wire size according to the length of the cable if there is a possibility that the voltage may drop.

Wiring Inspection

After completing wiring, check the following.

• Wiring is proper.

• Wire clippings or screws are not left in the Inverter.

• Screws are securely tightened.

• Bare wires in the terminals do not contact other terminals.

WARNING If the power supply is turned ON during the FWD (or

REV) RUN command is given, the motor will start automatically.

Turn the power supply ON after verifying that the

RUN signal is OFF.


NOTE

If the FWD (or REV) RUN command is given when the RUN command from the control circuit terminal is selected (n003

= 1), the motor will start automatically after the main circuit input power supply is turned ON.

5. Operating the Inverter


The Control Mode Selection (n002) is initially set to V/f control mode.

WARNING

• Only turn ON the input power supply after confirming that the Digital Operator or blank cover

(optional) are in place. Do not remove the Digital

Operator or the covers while current is flowing.


• Never operate the Digital Operator or DIP switches with wet hands.


• Never touch the terminals while current is flowing, even if the Inverter is stopping.


CAUTION

• Never touch the heatsinks, which can be extremely hot.

Failure to observe this caution may result in harmful burns to the body.

• It is easy to change operation speed from low to high. Verify the safe working range of the motor and machine before operation.

Failure to observe this caution may result in injury and machine damage.

• Install a holding brake separately if necessary.




• All the constants set in the Inverter have been preset at the factory. Do not change the settings unnecessarily.

The Inverter may be damaged.

Test Run

The Inverter operates when a frequency (speed) is set.

There are four operating modes for the Varispeed V7:

1. RUN command from the Digital Operator (potentiometer/digital setting)

2. RUN command from the control circuit terminals

3. RUN command from DeviceNet communications

Prior to shipping, the Inverter is set up to receive the RUN command and frequency reference from the Operator. Below are instructions for running the Varispeed V7 using the JVOP-147 Digital Operator (without potentiometer). For instructions on operation, refer to page 53.

Operation reference or frequency reference constants can be selected separately as shown below.

Description of the DeviceNet Functions

DeviceNet-compatible Inverters support the AC Drive Profile defined in DeviceNet specifications. No special settings are needed to operate, adjust, and monitor the Inverters from any DeviceNet master.

DeviceNet-compatible Inverters operate as Group 2 Only servers

(DeviceNet slaves) in the DeviceNet network. Two kinds of communications are possible with the master: I/O messages and explicit messages.

9: Enables DeviceNet communications.

Set this constant to 9 when setting the frequency through DeviceNet communications.

Always set the number of motor poles

(2 to 39).

In DeviceNet standards, the motor speed is expressed in units of r/min.

The Inverter uses this constant setting to convert the frequency to r/min.


I/O Message Communications

The DeviceNet-compatible Inverters use poll command/response messages for I/O message communications. Select one of the seven supported I/O instances and transfer I/O data with the master. I/O messages are always transferred between the Inverter and master at the fixed communications period whether or not there have been changes to the I/O data.

Basic I/O Instances

This is a standard I/O instance type defined in DeviceNet’s AC Drive

Explicit Message Communications

The DeviceNet-compatible Inverters can transfer explicit messages

(defined in DeviceNet specifications) to and from a DeviceNet master.

Various kinds of data can be set and referenced from the master, ranging from DeviceNet-related settings to the Inverter’s control data. Unlike I/

O message communications, which are performed at regular intervals, the explicit messages can be sent from the master at any time and corresponding response messages will be returned.

Description

This value is set automatically, so there is no need to check it.

Contains the MAC ID of the master or slave that is the other node involved in the data transfer.

In a request message, the service code specifies the requested operation such as reading or writing data.

In a normal response, bit 15 (the most significant bit) of the request service code will be turned ON in the response. If an error occurred, the code 94 will be returned.

Examples:

• 0E: Read request

• 8E: Normal read response

• 10: Write request

• 90: Normal write response

• 94: Error response

Each DeviceNet function is divided into these 3 codes. When specifying data, specify it with these

3 codes.

Request: Contains the write data.

Response: Contains the read data or error code.

---

When writing a constant from the master through communications, always execute the ENTER command after changing the constant.

When a constant is changed, the new value is written to the constant data area in the Inverter’s RAM. The ENTER command writes the constant data from RAM to the non-volatile memory in the Inverter. The

ENTER command can be executed by writing data to register number

0900H while the Inverter is stopped.

Since the Inverter’s EEPROM can be overwritten a limited number of times (100,000 times), do not execute the ENTER command too frequently. When two or more constants are being changed, execute the

ENTER command once after changing all of the constants.

CAUTION

While the constant is being stored after an ENTER command was issued, response to the commands or data input with the keys on the Digital Operator

(JVOP-140) becomes poor. Be sure to take some measures for an emergency stop by using the external terminals (setting the external terminal to run command priority, or setting the multi-function input terminal to external fault, external baseblock or emergency stop).

Typical Setting of the V/f Pattern

Set the V/f pattern according to the application as described below. For

400-V Class Inverters, the voltage values (n012, n015, and n017) should be doubled. When running at a frequency exceeding 50/60 Hz, change the Maximum Output Frequency (n011).

Note: Always set the maximum output frequency according to the motor characteristics.

1. For General-purpose Applications

Motor Specification: 60 Hz Motor Specification: 50 Hz

(Factory setting)

2. For Fans/Pumps


3. For Applications Requiring High Starting Torque


130

Increasing the voltage of the V/f pattern increases motor torque, but an excessive increase may cause motor overexcitation, motor overheating, or vibration.

Note: Constant n012 must be set to motor rated voltage.


Full-range Automatic Torque Boost (when V/f Mode Is

Selected: n002=0)

The motor torque requirement changes according to load conditions.

The full-range automatic torque boost adjusts the voltage of the V/f pattern according to requirements. The Varispeed V7 automatically adjusts the voltage during constant-speed operation, as well as during acceleration.

The required torque is calculated by the Inverter.

This ensures tripless operation and energy-saving effects.

Normally, no adjustment is necessary for the Torque Compensation

Gain (n103 factory setting: 1.0). When the wiring distance between the

Inverter and the motor is long, or when the motor generates vibration, change the automatic torque boost gain. In these cases, set the V/f pattern (n011 to n017).

Adjustment of the Torque Compensation Time Constant (n104) and the

Torque Compensation Iron Loss (n105) are normally not required.

Adjust the torque compensation time constant under the following conditions:

• Increase the setting if the motor generates vibration.

• Reduce the setting if response is slow.

Precautions for Voltage Vector Control Application

Vector control requires motor constants. The Yaskawa standard motor constants have been set at the factory prior to shipment. Therefore, when a motor designed for an Inverter is used or when a motor from any other manufacturer is driven, the required torque characteristics or speed control characteristics may not be maintained because the constants are not suitable. Set the following constants so that they match the required motor constants.

Adjustment of the Torque Compensation Gain (n103) and the Torque

Compensation Time Constant (n104) is normally not required.

Adjust the torque compensation time constant under the following conditions:

• Increase the setting if the motor generates vibration.


Adjust the Slip Compensation Gain (n111) while driving the load so that the target speed is reached. Increase or decrease the setting in increments of 0.1.

• If the speed is less than the target value, increase the slip compensation gain.


• If the speed is more than the target value, reduce the slip compensation gain.

Adjustment of the Slip Compensation Time Constant (n112) is normally not required. Adjust it under the following conditions:


• Increase the setting if speed is unstable.

3. To stop the Inverter and generate a fault at overtorque detection, set n096 to 2 or 4. At detection, the operator will display an fault (ON).


Overtorque Detection Level (n098)

Set the overtorque detection current level in units of 1%. (Inverter rated current = 100%) When detection by the output torque is selected, the motor rated torque becomes 100%.


Overtorque Detection Time (n099)

If the time that the motor current exceeds the Overtorque Detection

Level (n098) is longer than Overtorque Detection Time (n099), the overtorque detection function will operate.

Jump Frequencies (n083 to n086)

This function allows the prohibition or “jumping” of critical frequencies so that the motor can operate without resonance caused by the machine system. This function is also used for dead band control. Setting the values to 0.00 Hz disables this function.

Set prohibited frequencies 1, 2, and 3 as follows:

OUTPUT FREQUENCY n083 ≥ n084 ≥ n085

If this condition is not satisfied, the Inverter will display for one second and restore the data to initial settings.

FREQUENCY REFERENCE

Operation is prohibited within the jump frequency ranges.

However, the motor will operate without jumping during acceleration/ deceleration.

Continuing Operation Using Automatic Retry Attempts (n082)

WARNING

When the fault retry function is selected, stand clear of the Inverter or the load. The Inverter may restart suddenly after stopping.




The Inverter can be set to restart and reset fault detection after a fault occurs. The number of self-diagnosis and retry attempts can be set to up to 10 in n082. The Inverter will automatically restart after the following faults occur:

OC (overcurrent)

OV (overvoltage)

The number of retry attempts is cleared to 0 in the following cases:

1. If no other fault occurs within 10 minutes after retry

2. When the FAULT RESET signal is ON after the fault is detected

3. When the power supply is turned OFF

Operating a Coasting Motor without Tripping

To operate a coasting motor without tripping, use the SPEED SEARCH command or DC injection braking at startup.

SPEED SEARCH Command

Restarts a coasting motor without stopping it. This function enables smooth switching between motor commercial power supply operation and Inverter operation.

Set a Multi-function Input Selection (n050 to n056) to 14 (SEARCH command from maximum output frequency) or 15 (SEARCH command from set frequency).

Build a sequence so that a FWD (REV) RUN command is input at the same time as the SEARCH command or after the SEARCH command.

If the RUN command is input before the SEARCH command, the

SEARCH command will be disabled.

Preventing the Motor from Stalling (Current

Limit)

This function automatically adjusts the output frequency and output current according to the load to continue operation without stalling the motor.

Stall Prevention (Current Limit) Level during Acceleration

(n093)

The electronic thermal overload function monitors the motor temperature based on Inverter output current and time to protect the motor from overheating. When the electronic thermal overload relay is enabled, an

error occurs, and the Inverter output is turned OFF to prevent excessive overheating in the motor. When operating with one Inverter connected to one motor, an external thermal relay is not needed. When operating more than one motor with one Inverter, install a thermal relay on each motor.

General-purpose Motors and Inverter Motors

Induction motors are classified as general-purpose motors or Inverter motors based on their cooling capabilities. The motor overoad function operates differently for these two motor types.

Energy-saving Control Mode (n140, n158)

The voltage for the best motor efficiency is calculated when operating in energy-saving control mode. The calculated voltage is used as the output voltage reference. The factory setting is set to the max. applicable motor capacity for a Yaskawa standard motor.

The greater the enegy-saving coefficient is, the greater the output voltage becomes.

When using a motor other than a Yaskawa standard motor, set the motor code corresponding to the voltage and capacity in n158. Then, change the setting of the energy-saving coefficient K2 (n140) by 5% to minimize the output power.

When the motor code is set in n158, the energy-saving coefficient K2, which corresponds to the motor code, must be set in n140.

Energy-saving Search Operation

In energy-saving control mode, the maximum applicable voltage is calculated using the output power. However, a temperature change or the use of another manufacturer’s motor will change the fixed constants, and the maximum applicable voltage may not be emitted. In the search operation, change the voltage slightly so that the maximum applicable voltage can be obtained.

Using Constant Copy Function

Constant Copy Function

The Varispeed V7 standard JVOP-140 Digital Operator can store constants for one Inverter. A backup power supply is not necessary because

EEPROM is used.

The constant copy function is possible only for the Inverters with the same product series, power supply specifications, and control mode (V/ f control or vector control). However, some constants may not be copied. It is also impossible to copy constants between Varispeed V7 and

VSmini J7 Inverters.

Prohibiting reading constants from the Inverter can be set in n177. The constant data cannot be changed when this constant is set.

If an alarm occurs when copying constants, PRGM will flash and copying will continue.

This function compares the constants stored in the Digital Operator with the constant in the Inverter. Verification is possible only for the Inverters with same product series, power supply specifications, and control mode (V/f control or vector control).

When the constants stored in the Digital Operator are the same as those in the Inverter, vFy will flash, and then End will be displayed.

8. Maintenance and Inspection

WARNING • Never touch high-voltage terminals on the Inverter.

Failure to observe this warning may result in an electrical shock.

• Disconnect all power before performing maintenance or inspection, and then wait at least one minute after the power supply is disconnected. Confirm that all indicators are OFF before proceeding.

If the indicators are not OFF, the capacitors are still charged and can be dangerous.

• Do not perform withstand voltage test on any part of the Varispeed V7.

The Inverter is an electronic device that uses semiconductors, and is thus vulnerable to high voltage.

• Only authorized personnel should be permitted to perform maintenance, inspection, or parts replacement.

(Remove all metal objects (watches, bracelets, etc.) before starting work.)

(Use tools which are insulated against electrical shock.)

Failure to observe these warnings may result in an electric shock.

CAUTION

• The control PCB employs CMOS ICs.

Do not touch the CMOS elements.

They are easily damaged by static electricity.

• Do not connect or disconnect wires, connectors, or the cooling fan while power is applied to the circuit.

Protective and Diagnostic Functions

This section describes the alarm and fault displays, the fault conditions, and the corrective actions to be taken if the Varispeed V7 malfunctions.

Inverter alarms are classified into alarm display and fault display.

Alarm display:When a minor fault occurs in the Inverter, the Digital

Operator flashes the display. In this case, the operation is continued, and restored automatically as soon as the cause is removed. Multi-function output can output the minor fault status to external devices.

Fault display: When a major fault occurs in the Inverter, the protective function operates, and the Digital Operator lights the display and shuts off the output to stop the Inverter. The fault can be output as a fault output to the external devices by multi-function output.

To reset the fault, turn ON the reset signal with the run command OFF or cycle the power after taking the corrective action.

* Selecting "always ON" mode at fan operation selection, the power must be cycled to release the alarm display.

Corrective Actions of Models with Blank Cover

1. Input fault reset or cycle the power supply OFF and ON.

2. When a fault cannot be corrected:

(1) Turn the power supply OFF and check the wiring and external circuit

(sequence).

(2) Turn the power supply OFF and replacce the blank cover with the

Digital Operator to display faults. The faults are displayes after turning the power ON.

219

Troubleshooting

Trouble

Communications disabled with

DeviceNet master.

Cause

Communications cable is incorrectly connected.

Baud rate is incorrectly set.

MAC ID is already used by another device.

Terminator is incorrectly connected or not connected on the communications line.

DeviceNet master does not operate.

Incorrect operation method is selected.

Selection of operation Run command selection (n003) is not set to

DeviceNet communications.

Corrective Actions

Check if the connector is incorrectly connected or disconnected. Make sure that the communications cable is correctly connected.

Set the baud rate to the same value as that of the DeviceNet master, and turn ON the power supply again.

Change the MAC ID so that it will not be the same as that of any other device, and turn ON the power supply again.

Check that the terminator is connected correctly on the communications line.

Check that the DeviceNet master is always operating correctly.

Set Run command selection (n003) to

DeviceNet communications.

Although DeviceNet communications established, the

Inverter does not run when an operation is started by the

DeviceNet master.

The motor does not operate when an external operation signal is input.

The operation method selection is wrong.

The run command (n003) is not set to

Control Circuit Terminal.

Set the run command (n003) to

Control Circuit Terminal.

A 3-wire sequence is in effect.

The multi-function input method

(n052) is set to 3-wire sequence, and the S2 control terminal is not closed.

The frequency reference is too low.

The input frequency reference is lower than the setting for the min.output frequency (n016).

Local mode is in effect.

To use a 3-wire sequence, make the wiring so that the S2 control terminal is closed. To use a 2-wire sequence, set the multi-function input (n052) to a value other than 3-wire sequence.

Input a frequency reference greater than the min. output frequency

(n016).

Set the LO/RE selection of the digital operator to RE.

220

9. Fault Diagnosis

Trouble

The motor stops. The torque is not output.

Cause

The stall prevention level during acceleration is too low.

Because the stall prevention level during acceleration (n093) is set too low, the output current reaches the set level, the output frequency is stopped, and the acceleration time is lengthened.

The stall prevention level during running is too low.

Because the stall prevention level during running (n094) is set too low, the output current reaches the set level, and the speed drops.

The load is too heavy.

If the load is too heavy, stall prevention is activated, the output frequency is stopped, and the acceleration time is lengthened.

When the maximum frequency was changed, the maximum voltage frequency was also changed.

Corrective Actions

Check if the stall prevention level during acceleration (n093) is set to an appropriate value.

Check if the stall prevention level during running (n094) is set to an appropriate value.

• Lengthen the set acceleration time

(n019).

• Reduce the load.

To increase the speed of a generalpurpose motor, only change the maximum frequency (n011).

The V/f set value is too low.

Set the V/f (n011 to n017) according to the load characteristics.

221

Trouble

The motor speed is unstable. The motor speed fluctuates when operating with a light load.

The digital operator does not turn ON.

Cause

The stall prevention level during running is too low.

Because the stall prevention level during running (n094) is too low, the output current reaches the set level and the speed drops.

The load is too heavy.

If the load is too heavy, stall prevention is activated, the output frequency is stopped, and the acceleration time is lengthened.

The carrier frequency is too high.

If operating the motor with a light load, a high carrier frequency may cause the motor speed to fluctuate.

The V/f set value is too high for a low speed operation.

Because the set value for the V/f is too high, over-excitation occurs at low speeds.

The maximum frequency and base frequency were incorrectly

adjusted.

Example: To operate a 60 Hz motor at

40 Hz or less, the maximum frequency and base frequency are set to 40 Hz.

The inverter is used for an operation at 1.5 Hz or less.

Corrective Actions

Check if the stall prevention level during running (n094) is set to an appropriate value.

Reduce the load.

Decrease the carrier frequency

(n080).

Set the V/f (n011 to 017) according to the load characteristics.

Set the maximum frequency (n011) and the base frequency (n013) according to the motor specifications.

The analog reference input is unstable and has noise interference.

The power is not being supplied.

The breaker or other component on the power input side is not turned ON, and the power is being not supplied.

The digital operator is not correctly mounted.

Because the digital operator is not correctly mounted, the display does not appear.

Do not use the V7 inverter for an operation that runs at 1.5 Hz or less.

For an operation at 1.5 Hz or less, use a different inverter model.

Increase the set value for the filter time constant (n070).

Check if the power is being supplied.

Mount the digiral operator correctly.

10. Specifications

• Ground Fault Interrupter:

Select a ground fault interrupter not affected by high frequencies. To prevent malfunctions, the current should be 200 mA or higher and the operating time 0.1 s or longer.

Example:

• NV series by Mitsubishi Electric Co., Ltd. (manufactured in 1988 and after)

• EGSG series by Fuji Electric Co., Ltd. (manufactured in 1984 and after)

• AC and DC Reactor:

Install an AC reactor to connect to a power supply transformer of large capacity (600 kVA or more) or to improve power factor on the power supply side.

• Noise Filter:

Use a noise filter exclusively for Inverter if radio noise generated from the Inverter causes other control devices to malfunction.

NOTE

1. Never connect a general LC/RC noise filter to the Inverter output circuit.

2. Do not connect a phase-advancing capacitor to the I/O sides and/or a surge suppressor to the output side.

3. When a magnetic contactor is installed between the

Inverter and the motor, do not turn it ON/OFF during operation.

For the details of the peripheral devices, refer to the catalog.
