113-PCRMD - Max. number of revolutions in referencing
Source: Position Control Referencedrive Maximum Distance
Function: Indication of the maximum number of revolutions for a reference run without the reference
cam having been activated. When this threshold value is exceeded output OSxx “Referen-
cing error“ is set, if the output has been assigned the REERR or REFOK (= Reference run
successful) function with the function selector FOSxx.
For stepper motor interface and electronic gearing modes.
112-PCRV - Referencing speed
Source: Position Control Reference Velocity
Function: Maximum positioning speed during referencing. The positioning speed must be in the
range - SCSMX ... + SCSMX (parameter no. 384).
For stepper motor interface and electronic gearing modes.
380-PCTS - Sampling time of position controller
Source: Position Controller Time Sampling
Function: Sampling time of the position controller (250 µs or 500 µs on MC7000 with 4 kHz switching
frequency PMFS).
117-PCZS - Offset machine zero relative to reference point
Source: Position Control Zeropoint Offset
Function: Distance between reference point and machine zero.
The machine zero is shifted by this value (zero correction).
For stepper motor interface and electronic gearing modes.
