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

The motor identification routine and the "rotating measurement" (p1900) can be activated
from the commissioning wizard in STARTER.
