Operation
If the DSZR/ZRN instruction turns ON,
mechanical zero return will be started at

sensor is turned on, the speed will be
reduced to the creep speed. If the zero-
phase signal is input, the operation will be
stopped, and the zero return will be

(If the ZRN instruction is used, the dog
sensor will be turned off to stop the
operation.)
If the ABS instruction turns ON, the
current motor address will be read out
from the servo amplifier.
