SINAMICS G120 (CU 2x0x): MOP setpoint be tracking to another setpoint source.

  • Entry
  • Associated product(s)
In some applications (e.g. AUTO / MANUAL changeover), the setpoint is to be changed over from the main setpoint 1 (MSP 1, e.g. an analog setpoint) to main setpoint 2 (MSP 2, MOP setpoint) , without any setpoint jumps/steps (bumpless transfer).

How can the MOP setpoint be tracked to another setpoint source with a SINAMICS G120 CU (from V3.0)?

Tracking the MOP-setpoint (Motorized-Potentiometer-setpoint) to another setpoint source with bumpless setpoint changeover from MSP 1 to MSP 2 is explained in the following document. Further, script files for the various examples are provided in the attachment.
