7 Troubleshooting
50 MAGNETEK HPV1000 AC Elevator Drive Technical Manual
Er-13
(auto-tune)
Leakage Inductance Error
Drive was unable to complete tuning for leakage inductance within 300
seconds.
• Check all wiring and correct any mistakes.
• Double-check the motor current value that was entered for Rated Current in
the U9 sub-menu for auto-tuning.
• Check the motor rated current value written on the motor nameplate and
enter the correct value.
Er-18
(auto-tune)
Induction Voltage Error
The induced voltage constant attempted to set a value outside the allowable
setting range.
• Double-check the data entered in the PM auto-tune in the U9 sub-menu,
and perform auto-tuning again.
Er-19
(auto-tune)
Inductance Error
The induced voltage constant attempted to set a value to PM Mtr Ind V1 (A5)
that is outside the allowable range.
• Double-check the data entered in the PM auto-tune in the U9 sub-menu,
and perform auto-tuning again.
Er-20
(auto-tune)
Stator Resistance Error
Stator resistance tuning attempted to set a value to PM Mtr d Induct (A5) that
is outside the allowable setting range.
• Double-check the data entered to the U9 Menu and perform Auto-Tuning
again.
Er-21
(auto-tune)
Z Pulse Correction Error
Motor is coasting when auto-tuning is initiated.
• Make sure the motor has stopped completely. Repeat auto-tuning.
Either the motor or the encoder on the motor is not properly wired.
• Check the wiring for the motor and the encoder. Repeat auto-tuning.
The direction for the encoder on the motor is not properly wired.
• Check the direction of the motor with Motor Rotation (C1) or encoder with
Encoder Connect (C1).
Encoder is damaged.
• Check the signal output from the encoder attached to the motor. Replace
the encoder if damaged.
PG-E3 option detected excess position error with the ERN1387 encoder.
• If other possible solutions are not successful, perform auto-tuning of
PG-E3 encoder characteristics.
Er-22
(auto-tune)
Initial Rotor Pole Search Error
Parameters set by Initial Rotor Pole Search Tuning were outside the
acceptable range, or during normal operation, pole diversion exceeded 20
degrees.
• Switch to an absolute encoder and to the PG-F3 option card.
Er-23
(auto-tune)
Non-rotating Encoder Offset Tuning
Warning
Pole diversion exceeded 15 degrees three times, or parameters set by Encoder
Offset Tuning were outside the acceptable range.
• Remove the ropes and conduct a “PolePos-rotate” for PM Tuning Mode
(U9) for a rotational auto-tuning for encoder offset.
Er-24
(auto-tune)
Auto-Tuning Error for PG-E3 Encoder
Characteristics
The signal lines between the PG-E3 option card and encoder are disconnected
at the R+ and R- terminals, or there is excessive electrical interference at the
PG-E3 option card.
• Refer to the installation manual for the PG-E3 option card for information
on correct connection of signal lines.
The software for the PG-E3 option card does not support the Auto-Tuning of
PG-E3 encoder characteristics.
Err
EEPROM R/W Err
Data cannot be written to the EEPROM.
Noise has corrupted data while writing to the EEPROM.
• Press the ENTER button.
• Correct the parameter setting.
• Cycle power to the drive.
• If the problem continues, replace the control board or the entire drive.
Contact Magnetek for instructions on replacing the control board.
Hardware problem.
• If the problem continues, replace the control board or the entire drive.
Contact Magnetek for instructions on replacing the control board.
FrL
No Speed Ref Flt
No speed was selected while an Up or
Down command was entered.
• Make sure the selected speed selection method matches the elevator
controller sequence.
• Make sure the elevator controller is connected properly.
• Make sure the elevator controller selects the speed properly.
