The following parameters can be optionally entered:

Optional motor data

Equivalent circuit diagram for motor data

● Field weakening up to approx. 1.2 * rated speed (this depends on the drive converter

● Flying restart

● Vector closed-loop speed and torque control

● Vector V/f control for diagnostics

● Motor identification

● Speed controller optimization (rotating measurement)

● Thermal protection via temperature sensor (PTC/KTY)

● All encoders that can be connected to an SMC10, SMC20 or SMC30 are supported.

● Operation with or without encoder is possible.

Supplementary conditions

Depending on the terminal voltage and load cycle, the maximum torque can be taken from

the motor data sheets / project design instructions.
