Homing Reference Signal Selection (d211), Reference Signal for Homing
Offset (d212)
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 of
fset (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 (d212) 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 (d211) setting is disabled.
