7 Troubleshooting
48 MAGNETEK HPV1000 AC Elevator Drive Technical Manual
End7
(auto-tune)
No-Load Current Alarm
The entered no-load current value was outside the allowable range.
• Check and correct the faulty motor wiring.
Auto-Tuning results were less than 5% of the motor rated current.
• Double-check the data that was entered for the auto-tuning process in
No-Load Current (A5).

Rescue Operation Speed Warning
High frequency injection calculations for the battery power supply were
below 10 Hz.
• For Rescue Operation, either switch to a larger battery (at least 280 VDC
for a 200 V class drive, 560 VDC for a 400 V class drive, or 700 VDC for a
600 V class drive) or switch to an absolute encoder and the PG-F3 option
card.
End9
(auto-tune)
Rescue Operation Rotor Pole Position
Search Warning
While operating from the backup battery, pole diversion exceeded 40 degrees.
• For Rescue Operation, either switch to a larger battery (at least 280 VDC
for a 200 V class drive, 560 VDC for a 400 V class drive, or 700 VDC for a
600 V class drive) or switch to an absolute encoder and the PG-F3 option
card.
End10
(auto-tune)
Rescue Operation Rotor Polarity
Detection Warning
While operating from the backup battery, the Id value between poles was less
than 5%.
• For Rescue Operation, either switch to a larger battery (at least 280 VDC
for a 200 V class drive, 560 VDC for a 400 class drive, or 700 VDC for a
600 class drive) or switch to an absolute encoder and the PG-F3 option
card.

ID Mismatch
Attempted to acquire machine data from an encoder that does not have any
machine data written to it yet.
• Try again after writing machine data to the encoder.

Motor Data Error
Motor data or data entered during Auto-Tuning was incorrect.
• Check that the motor data entered to U9 matches motor nameplate input
before Auto-Tuning.
• Start Auto-Tuning over again and enter the correct information.
Rated Motor Power and Rated Motor Current settings in U9 Menu do not
match.
• Check the drive and motor capacities.
• Correct the settings of parameters Rated Motor Power (U9) and Rated
Motor Current (U9).
Motor rated current and detected no-load current are not consistent with each
other.
• Check the motor rated current and no-load current.
• Correct the settings of parameters Rated Motor Current (U9) and No-Load
Current (A5).
Base Frequency (U9) and Rated Motor Speed (U9) do not match.
• Set Base Frequency (U9) and Rated Motor Speed (U9) to the correct value.
• Check if the correct pole number was entered to Number of Poles (U9).
Er-02
(auto-tune)
Alarm
An alarm was triggered during Auto-Tuning.
• Exit the Auto-Tuning menu, check the alarm code, remove the alarm cause,
and repeat Auto-Tuning.
Er-03
(auto-tune)
Escape Key Input
Auto-tuning canceled by pressing ESC key.
• Auto-tuning did not complete properly and will have to be performed
again.
Er-04
(auto-tune)
Line-to-Line Resistance 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.
• Reset auto-tuning and enter the correct information.
Results from auto-tuning are outside the parameter setting range or the tuning
process took too long, or the motor cable or cable connection is faulty.
• Check and correct faulty motor wiring.
