Short Description Reference Offset


The ROFFS parameter is used for Resolver or single-turn encoder (homing to reference point is possible)

The ROFFS parameter can be used to assign a freely chosen absolute position as the reference position (zero position) that will be reached at the end of a homing movement.
The scaling of the position depends on the settings for PGEARI, PGEARO, PRBASE.
If the resolution is set to 1 (PGEARI=PGEARO), then internal units (counts) will be used.

If a homing is executed and the feedback is an absolute encoder, then the drive calculates after completion of homing a reference offset and stores it automatically in the serial EEPROM.
