Digital Operator Display Error Name
End8 Rescue Operation Speed Warning
Cause Possible Solutions
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 the 400 V class) or
switch to an absolute encoder and the PG-F3 option card.
Digital Operator Display Error Name
End9 Rescue Operation Rotor Pole Position Search Warning
Cause Possible Solutions
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 the 400 V class) or
switch to an absolute encoder and the PG-F3 option card.
Digital Operator Display Error Name
End10 Rescue Operation Rotor Polarity Detection Warning
Cause Possible Solutions
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 the 400 V class) or
switch to an absolute encoder and the PG-F3 option card.
Digital Operator Display Error Name
Er-01 Motor Data Error
Cause Possible Solutions
Motor data or data entered during Auto-Tuning was
incorrect. • 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.
Motor output power and motor-rated current settings
(T1-02 and T1-04) do not match. • Check the drive and motor capacities.
• Correct the settings of parameters T1-02 and T1-04.
Motor rated current and detected no-load current are
not consistent with another. • Check the motor rated current and no-load current.
• Correct the settings of parameters T1-04 and E2-03.
Base frequency and motor rated speed (T1-05 and
T1-07) do not match. • Set T1-05 and T1-07 to the correct value.
• Check if the correct pole number was entered to T1-06.
Digital Operator Display Error Name
Er-02 Alarm
Cause Possible Solutions
An alarm was triggered during Auto-Tuning. Exit the Auto-Tuning menu, check the alarm code, remove the alarm cause, and repeat Auto-Tuning.
Digital Operator Display Error Name
Er-03 STOP Button Input
Cause Possible Solutions
Auto-Tuning canceled by pressing STOP button. Auto-Tuning did not complete properly and will have to be performed again.
Digital Operator Display Error Name
Er-04 Line-to-Line Resistance Error
Cause Possible Solutions
Motor data entered during Auto-Tuning was
incorrect. • 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.
Results from Auto-Tuning are outside the parameter
setting range or the tuning process took too long.
Check and correct faulty motor wiring.
Motor cable or cable connection faulty.
Digital Operator Display Error Name
Er-05 No-Load Current Error
Cause Possible Solutions
Motor data entered during Auto-Tuning was
incorrect. • 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.
Results from Auto-Tuning are outside the parameter
setting range or the tuning process took too long.
• 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.
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.
Digital Operator Display Error Name
Er-08 Rated Slip Error
Cause Possible Solutions
Motor data entered during Auto-Tuning was
incorrect. • 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.
Drive-calculated values outside parameter setting
range or the tuning process took too long.
• 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.
