Digital Operator Display
End8
Cause
High frequency injection calculations for the battery
power supply were below 10 Hz.
Digital Operator Display
End9
Cause
While operating from the backup battery, pole
diversion exceeded 40 degrees.
Digital Operator Display
End10
Cause
While operating from the backup battery, the Id
value between poles was less than 5%.
Digital Operator Display
Er-01
Cause
Motor data or data entered during Auto-Tuning was
incorrect.
Motor output power and motor-rated current settings
(T1-02 and T1-04) do not match.
Motor rated current and detected no-load current are
not consistent with another.
Base frequency and motor rated speed (T1-05 and
T1-07) do not match.
Digital Operator Display
Er-02
Cause
An alarm was triggered during Auto-Tuning.
Digital Operator Display
Er-03
Cause
Auto-Tuning canceled by pressing STOP button.
Digital Operator Display
Er-04
Cause
Motor data entered during Auto-Tuning was
incorrect.
Results from Auto-Tuning are outside the parameter
setting range or the tuning process took too long.
Motor cable or cable connection faulty.
Digital Operator Display
Er-05
Cause
Motor data entered during Auto-Tuning was
incorrect.
Results from Auto-Tuning are outside the parameter
setting range or the tuning process took too long.
The load during Rotational Auto-Tuning was too
high.
Digital Operator Display
Er-08
Cause
Motor data entered during Auto-Tuning was
incorrect.
Drive-calculated values outside parameter setting
range or the tuning process took too long.

Rescue Operation Speed Warning
For Rescue Operation, either switch to a larger battery (at least 280 Vdc for a 200 V class drive, 560 Vdc for the 400 V class) or
switch to an absolute encoder and the PG-F3 option card.
Rescue Operation Rotor Pole Position Search Warning
For Rescue Operation, either switch to a larger battery (at least 280 Vdc for a 200 V class drive, 560 Vdc for the 400 V class) or
switch to an absolute encoder and the PG-F3 option card.
Rescue Operation Rotor Polarity Detection Warning
For Rescue Operation, either switch to a larger battery (at least 280 Vdc for a 200 V class drive, 560 Vdc for the 400 V class) or
switch to an absolute encoder and the PG-F3 option card.
Motor Data Error
• Check that the motor data entered to T1 parameters matches motor nameplate input before Auto-Tuning.
• Start Auto-Tuning over again and enter the correct information.
• Check the drive and motor capacities.
• Correct the settings of parameters T1-02 and T1-04.
• Check the motor rated current and no-load current.
• Correct the settings of parameters T1-04 and E2-03.
• Set T1-05 and T1-07 to the correct value.
• Check if the correct pole number was entered to T1-06.
Alarm
Exit the Auto-Tuning menu, check the alarm code, remove the alarm cause, and repeat Auto-Tuning.
STOP Button Input
Auto-Tuning did not complete properly and will have to be performed again.
Line-to-Line Resistance Error
• Make sure the data entered to the T1 parameters match the information written on the motor nameplate.
• Restart Auto-Tuning and enter the correct information.
Check and correct faulty motor wiring.
No-Load Current Error
• Make sure the data entered to the T1 parameters match the information written on the motor nameplate.
• Restart Auto-Tuning and enter the correct information.
• Check and correct faulty motor wiring.
• Perform Rotational Auto-Tuning. Remember that the rope must be fully removed from the motor and the brake must be released to
perform Rotational Auto-Tuning.
• 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.
Rated Slip Error
• Make sure the data entered to the T1 parameters match the information written on the motor nameplate.
• Restart Auto-Tuning and enter the correct information.
• Check and correct faulty motor wiring.
• Perform Rotational Auto-Tuning. Remember that the rope must be fully removed from the motor and the brake must be released to
perform Rotational Auto-Tuning.
