Homing Reference Signal Selection (3037Hex-0CHex), Reference Signal
for Homing Offset (3037Hex-0DHex)
The reference signal for homing is to switch from the homing frequency to the homing creep fre-
quency. The reference signal for homing starts incrementing of the homing offset. Ordinarily
, the
signal of the origin limit switch is taken as the reference signal for homing and the Z phase signal is
taken as the reference signal for homing offset (factory default). When return-to-origin is configured
using other signals, select the reference signal for homing and reference signal for homing offset
according to the table below. When Reference Signal for Homing Offset (3037Hex-0DHex) is set to
other than “0: Z pulse of position encoder”, the reference signal for homing is not included in the
configuration, and so the Homing Reference Signal Selection (3037Hex-0CHex) setting is disabled.
