Description
| The ROFFSABS parameter is used with an absolute encoder (multi-turn, homing to reference point is also possible) The ROFFSABS sets an offset to the absolute encoder position. This procedure is executed by drive power on. The parameter must be saved in the EEPROM (using the SAVE or HSAVE command) after every alteration of the ROFFSABS variable, and the amplifier must then be switched off and on again (COLDSTART command). Depending on the setting of bit 0x100 of DRVCNFG2, the ROFFSABS parameter is used either from the drive memory (bit = 0, saved with SAVE) or from the encoder memory (bit = 1, saved with HSAVE). Example: If a position 10000 (PFB) is shown when the amplifier is switched on with ROFFSABS = 0, ROFFSABS = –10000 will shift the position to the value 0. |
