Evaluation of SERCOS state bit drive follows command (P-AXIS-00411)

P-AXIS-00411

Evaluation of SERCOS state bit drive follows command (SERCOS)

Description

Many SERCOS drives supply the information “drive follows command values” in bit 3 of their status word (bit mask 0x0008). Parameter P-AXIS-00411 can be used to ensure that this bit is taken into account for the calculation of the HLI state signal ready_for_power_on_r (gpAx[idxAx]^.lr_state.ready_for_power_on_r).
If this parameter is set, the HLI signal ready_for_power_on_r is only set when bits (0x4000 and 0x0008) are set in the SERCOS state word.

In the following cases, the HLI state signal ready_for_power_on_r (gpAx[idxAx]^.lr_mc_control.release_feedhold) is only calculated depending on SERCOS state bit 0x4000 even if P-AXIS-00411 is set:

  • SERCOS control bit 0x2000 (release feedhold, release_feedhold control unit) is not set.
  • The drive executes drive-controlled homing.

SERCOS state bit 0x8000 (Ready for power on) is not set.
