Features
● Field weakening up to approx. 1.2 * rated speed (this depends on the drive converter
supply voltage and the motor data, also refer to limitations/ constraints)
● Flying restart (for operation without encoder, only possible with additional VSM)
● 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.
Commissioning
We recommend the following points when commissioning:
● Commissioning Wizard in STARTER
The motor identification routine and the "rotating measurement" (p1900) can be activated
from the commissioning Wizard in STARTER.
