Motor identification:
• [1]: Recommended setting for closed-loop speed control. After an
ON command, the inverter identifies the motor data – and with a new
ON command, optimizes the speed controller.
• [2]: After an ON command, the inverter identifies the motor data at
standstill. Recommended setting for the following cases:
– You have selected "Speed control" as control mode, however the
– You have set "V/f control" as control mode.
• [3]: This setting only makes sense after the motor identification [2].
The inverter optimizes the speed controller at the next ON command.
• [11] or [12]: The setting is the same as [1] or [2], however with the
difference that after the motor identification, the inverter immediately
changes into the "Operation" state.
•
Calculating the motor parameters: Select "Complete calculation".
If you use an HTL encoder on the motor shaft for the speed control of
the inverter, either select one of the standard encoders or enter the en-
coder data.
