R escue Operation Rotor Pole Position Search Warning
C a u s e
P o s s i b l e S o l u t i o n s
W hile operating from the backup battery, pole
diversion exceeded 40 degrees.
For R escue 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.

R escue Operation Rotor Polarity Detection Warning
C a u s e
P o s s i b l e S o l u t i o n s
W hile operating from the backup battery, the Id
value between poles was less than 5%.
For R escue 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
C a u s e
P o s s i b l e S o l u t i o n s
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 o f 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 o f parameters T1-04 and E2-03.
Base frequency and motor rated speed (T1-05 and
T1-07) do not match.
• Set T1-05 and T 1-07 to the correct value.
• Check if the correct pole number was entered to T1-06.

P o s s i b l e S o l u t i o n s
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.

No-Load Current Error
C a u s e
P o s s i b l e S o l u t i o n s
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.
• D isconnect the motor from m achine 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.
