Non-rotating Autotuning for Line-to-Line Resistance (T1-01 = 2)
Non-rotating autotuning for line-to-line resistance can be used in any control mode. This is the only
possible autotuning for V/f control and V/f control with PG.
It can be used to improve the performance when the motor cable is long, the cable length has
changed or when the motor and inverter have different capacities.
To perform autotuning in V/f control or V/f control with PG, set T1-02 (Motor rated power) and T1-04
(Motor rated current) and then press the RUN key on the Digital Operator. The Inverter will supply
power to the non-rotating motor for approximately 20 seconds and the Motor line-to-line resistance
and cable resistance will be automatically measured.
Other Alarms and Faults During Autotuning

IMPORTANT
1. Power will be supplied to the motor during autotuning but the motor will not turn. Do not touch the motor
until autotuning has been completed.
2. Ensure that all motor contactors are closed before the autotuning is started.
3. To cancel autotuning press the STOP key on the Digital Operator.
