Description: This function is only required for synchronous motors and can be started when commissioning for the first time or
after replacing an encoder. The function acts on the active motor data set.
Alarm A07971 is output while the angular commutation offset is being determined. p1990 is automatically set to 0
after the angular commutation offset has been determined.
For p1990 = 1 (encoder adjustment with transfer), the following applies:
The angular commutation offset is determined and transferred into p0431.
For p1990 = 2 (encoder adjustment for checking), the following applies:
The angular commutation offset is determined and is not transferred into p0431. For a deviation of more than 6 °
electrical, fault F07413 is output.
For p1990 = 3 (encoder adjustment in operation), the following applies:
PolID procedure runs before the zero mark detection. The angular commutation offset is determined and transferred
into p0431. A fine adjustment (p1905) is then optionally possible.
Value: 0: Deactivated
1: Activated with transfer
2: Activated for checking
3: Activates encoder adjustment in operation
Dependency: In the simulation mode, the parameter cannot be written into.
When selecting the encoder adjustment, the changeover of the drive data sets is suppressed.
Encoder adjustment is only carried out if the function module for "speed/torque control" is activated (r0108.2 = 1).
Refer to: p0325, p0329, p0431, p1272, p1900
Caution: When the encoder is being adjusted, the motor must be operated without a load - and if a motor holding brake is
being used, this must be opened.
Description: Sets the angle that is added to the commutating angle.
Caution: If the angular correction is not correctly set, when changing over and with closed-loop torque control, the motor can
accelerate to high speeds in spite of the fact that a setpoint of zero has been entered.
Description: Sets the scaling for the runtime of the automatic encoder calibration and of the pole position identification technique
in which the current is injected.
Dependency: Refer to: p0341, p0342
