YASKAWA TOEPC7106170VA GA800 600 V Drive Installation & Primary Operation
Causes
The drive is trying to operate a specialized motor or a
motor that is larger than the maximum applicable
motor output of the drive.
A magnetic contactor was switched at the output.
The V/f pattern settings are incorrect.
The torque compensation gain is too large.
Electrical interference caused a problem.
The gain during overexcitation operation is too large.
The drive received a Run command while the motor
was coasting.
The control method is set incorrectly for the motor.
The motor main circuit cable is too long.
An overcurrent condition occurred during
overexcitation deceleration.
The option card connected to connector CN5-A is not
compatible.
The option card connected to connector CN5-A is not
compatible.
The same option cards or the same type of option
cards are connected to connectors CN5-A, B, and C.
A fault occurred in the option card.
A fault occurred in the option card.
A fault occurred in the option card.
A fault occurred in the option card.
The option card connected to connector CN5-B is not
compatible.
The option card connected to connector CN5-B was
changed during operation.
18 Troubleshooting
Possible Solutions
• Examine the motor nameplate, the motor, and the drive to make
sure that the drive rated current is larger than the motor rated
current.
• Replace the drive with a larger capacity model.
Set the operation sequence to not turn ON or OFF the magnetic
contactor while the drive is outputting voltage.
• Examine the ratios between the V/f pattern frequency and
voltage. Decrease the voltage if it is too high compared to the
frequency.
• Adjust E1-04 to E1-10 [V/f Pattern Parameters]. For motor 2,
adjust E3-04 to E3-10.
Decrease the value set in C4-01 [Torque Compensation Gain] to
make sure that the motor does not stall.
Examine the control circuit lines, main circuit lines, and ground
wiring, and decrease the effects of electrical interference.
• Find the time when the fault occurs.
• If the fault occurs at the same time as overexcitation operation,
decrease the value set in n3-13 [OverexcitationBraking (OEB)
Gain] and consider the motor flux saturation.
• Examine the sequence and input the Run command after the
motor fully stops.
• Set b3-01 = 1 [Speed Search at Start Selection = Enabled] or set
H1-xx = 61, 62 [Speed Search from Fmax or Fref] to input speed
search commands from the MFDI terminals.
Set A1-02 [Control Method Selection] correctly.
Replace the drive with a larger capacity model.
• Decrease the value set in n3-13 [OverexcitationBraking (OEB)
Gain].
• Decrease the value set in n3-21 [HSB Current Suppression
Level].
Connect the option card to the correct connector.
Note:
Encoder option cards are not compatible with connector CN5-A.
1. De-energize the drive.
2. Refer to the option card manual and correctly connect the
option card to the connector on the drive.
Connect the option card to the correct connector.
Note:
Use connectors CN5-C and CN5-B to connect two encoder
option cards.
1. De-energize the drive.
2. Make sure that the option card is correctly connected to the
connector.
3. If the problem continues, replace the option card.
1. De-energize the drive.
2. Make sure that the option card is correctly connected to the
connector.
3. If the problem continues, replace the option card.
1. De-energize the drive.
2. Make sure that the option card is correctly connected to the
connector.
3. If the problem continues, replace the option card.
1. De-energize the drive.
2. Make sure that the option card is correctly connected to the
connector.
3. If the problem continues, replace the option card.
Connect the option card to the correct connector.
Note:
DO-A3, AO-A3, PG-B3, and PG-X3 options can connect to
connector CN5-B. Use connector CN5-C when connecting only
one encoder option card.
1. De-energize the drive.
2. Refer to the option card manual and correctly connect the
option card to the connector on the drive.
