13.2 Servo control for asynchronous motor (SC-ASM)
The motor control is based on a feedback, field-oriented and cascaded controller structure
and enables a dynamic and stable operation in all four quadrants.
Preconditions
•
The servo control (SC ASM) is only suitable for asynchronous motors.
•
The servo control (SC ASM) requires a feedback of the position.

13.3 Sensorless control for synchronous motor (SL-PSM)
13.3.1 Required commissioning steps
1
.
Optional: Activate flying restart circuit:
•
From firmware version 4 onwards, a flying restart circuit for the synchronous motor up
to speeds lower than half the rated speed is supported.
•
If the flying restart circuit shall be used, set the start method "Flying restart circuit [2]"
in . More settings are not required for the flying restart circuit at sensorless control of a
synchronous motor.
2
.
Optional for a speed control with torque limitation in operating mode 0x6060 = "MS:
Velocity mode [-2]":
•
Select the source in for the positive torque limit source and set it accordingly.
The torque limitation (parameter 0x2949:001/002) can only be used for open-
loop controlled operation of the SL-PSM, not for closed-loop controlled opera-
tion.
•
Select the source in for the negative torque limit source and set it accordingly.
