7 Troubleshooting
MAGNETEK HPV1000 AC Elevator Drive Technical Manual 49
Er-05
(auto-tune)
No-Load Current Error
Motor data entered during auto-tuning was incorrect.
• Make sure the data entered in the U9 sub-menu for auto-tune match the
information written on the motor nameplate.
• Restart auto-tuning and enter the correct information.
Results from auto-tuning are outside the parameter setting range or the tuning
process took too long.
• Check and correct faulty motor wiring.
• Perform a “standard tuning” the U9 sub-menu for a rotational auto-tuning.
Remember that the rope must be fully removed from the motor and the
brake must be released to perform a rotational auto-tuning.
The load during rotational auto-turning was too high.
• Disconnect the motor from machine and restart auto-tuning. If motor and
load cannot be uncoupled, make sure the load is lower than 30%.
• If a mechanical brake is installed, make sure it is fully lifted during tuning.
Er-08
(auto-tune)
Rated Slip Error
Motor data entered during auto-tuning was incorrect.
• Make sure the data entered in the U9 sub-menu for auto-tune match the
information written on the motor nameplate.
• Restart auto-turning and enter the correct information.
Drive-calculated values outside parameter setting range or the tuning process
took too long.
• Check and correct faulty motor wiring.
• Perform a “standard tuning” in the U9 sub-menu for a rotational
auto-tuning. Remember that the rope must be fully removed from the
motor and the brake must be released to perform a rotational auto-tuning.
The load during rotational auto-tuning was too high.
Disconnect the motor from machine and restart auto-tuning. If motor and load
cannot be uncoupled make sure that the load is lower than 30%.
• If a mechanical brake is installed, make sure it is fully lifted during tuning.
Er-09
(auto-tune)
Acceleration Error
The motor did not accelerate for the specified acceleration ramp.
• Lower the acceleration rates in the A2 sub-menu.
Torque limit when motoring is too low.
• Check the settings of Mtr Torque Limit (A1) and Regen Torq Limit (A1).
• Increase the setting of Mtr Torque Limit (A1) and Regen Torq Limit (A1).
The load during rotational auto-tuning was too high.
• Disconnect the motor from machine and restart auto-tuning. If motor and
load cannot be uncoupled make sure the load is lower than 30%.
• If a mechanical brake is installed, make sure it is fully lifted during tuning.
Er-10
(auto-tune)
Motor Direction Error
The encoder signal lines are not properly connected to the drive.
• Check and correct wiring to the encoder.
Motor and encoder direction are opposite.
• Check the Speed Feedback (D1) while turning the motor manually in
forward direction. If the sign displayed is negative, change the setting of
Encoder Connect (C1).
The load pulled the motor in the opposite direction of the speed reference and
the torque exceeded 100%.
• Uncouple the motor from the load and repeat auto-tuning.
Er-11
(auto-tune)
Motor Speed Fault
Torque reference is too high.
• Lower the acceleration rate in the A2 sub-menu.
• Disconnect the machine from the motor, if possible.
Er-12
(auto-tune)
Current Detection Error
One of the motor phases is missing: (U/T1, V/T2, W/T3).
• Check motor wiring and correct any problems.
Current exceeded the current rating of the drive, or the current is too low.
• Check the motor wiring for a short between motor lines.
• Make sure the motor contactor is closed during tuning.
• Replace either the control board or the entire drive. For instructions on
replacing the control board, contact Magnetek.
Attempted auto-tuning without motor connected to the drive.
• Manually push the motor contactor close while performing the auto-tune.
• Connect the motor and perform auto-turning.
Current detection signal error.
• Replace either the control board or the entire drive. For instructions on
replacing the control board, contact Magnetek.
