4.17 Instructions for commissioning induction motors (ASM)
Features
● 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
● 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.
Depending on the terminal voltage and load cycle, the maximum torque can be taken from
the motor data sheets / configuration instructions.
Commissioning
We recommend the following points when commissioning:
● Commissioning wizard in STARTER
● Motor identification (standstill measurement p1910)
● Rotating measurement (p1960)
The optional motor data can be entered if it is known. Otherwise, it is estimated using the
rating plate data or is determined using a motor identification routine or speed controller
optimization.

supply voltage and the motor data, also refer to supplementary conditions).
The motor identification and the "rotating measurement" (p1900) can be activated in the
commissioning wizard.
