In the Man Op(Manual operation) interface, press the left F4 key to enter the
BkTMech0(Back to mechanical zero) interface. At this time, the BkTMech0(Back to
mechanical zero) key color is negative display, and the system is in the
BkTMech0(Back to mechanical zero) state. The Bk0 HSpd(Back to zero high speed)
or Bk0 LSpd(Back to zero low speed) speed parameter of Back to mechanical
zero (((( reference point )))) is set in the Spd Pars(Speed parameters) area of the Pars
Set(Parameters settings) area, and is the fixed mode(the rate key is valid ).
Through the keys

on the controller panel or the direction
keys of external IO settings, the single direction Back to mechanical zero(mechanical
reference point) operation of the motor can be controlled. Before completing the
BkTMech0(Back to mechanical zero) operation, only the Paus(Pause) key is valid.
Back to mechanical zero is a set of combined actions. The premise is first to set
a set of zero point switches(both mechanical and photoelectric switches are allowed),
assuming that the switches are in the N.O.(Normally open) state.
