S1 series standard inverter
Note:
1. Motor parameters must be set correctly according to motor nameplate;
2. If rotary autotuning is selected during motor autotuning, it is a must to disconnect the motor from
load to put the motor in static and no-load state, failed to do so may lead to inaccurate autotuned
results. At this time, the asynchronous motor can autotune P02.06–P02.10
3. If static autotuning is selected during motor autotuning, there is no need to disconnect the motor
from load, as only part of the motor parameters have been autotuned, the control performance
may be impacted, under such situation, the asynchronous motor can autotune P02.06–P02.10
4. Motor autotuning can be carried out on current motor only, if users need to perform autotuning on
the other motor, switch over the motor through selecting the switch-over channel of motor 1 and
motor 2 by setting the ones of P08.31.
