YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
Causes
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 motor main circuit cable is too long.
The relay or contactor on the soft-charge bypass relay
is damaged.
An overcurrent condition occurred during
overexcitation deceleration.
Causes
The output circuit between the drive and the motor is
open, and the drive output current is less than 5% of
E2-01 [Motor Rated Current (FLA)].
Causes
The option card connected to connector CN5 is not
compatible.
Causes
The option card connected to connector CN5 is not
compatible.
Causes
A fault occurred in the option card.
Causes
A fault occurred in the option card.
Possible Solutions
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.
Replace the drive with a larger capacity model.
• Re-energize the drive.
• If the fault stays, replace the control board or the drive.
• Decrease the value set in n3-13 [OverexcitationBraking (OEB)
Gain].
• Decrease the value set in n3-21 [HSB Current Suppression
Level].
Possible Solutions
Close the disconnected output circuit between the drive and the
motor.
Possible Solutions
Connect the option card to the correct connector.
Note:
Encoder option cards are not compatible with connector CN5.
Possible Solutions
1. De-energize the drive.
2. Refer to the option card manual and correctly connect the
option card to the connector on the drive.
Possible Solutions
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.
Possible Solutions
1. De-energize the drive.
