ORIENTATION CONTROL—A500(L)
3.6.2
Orientation starting during stop.
Switch on the orientation command (X22), then switch on the start signal to start and accelerate the motor
to the orientation speed set in Pr. 351 "orientation speed" and perform orientation using the same
procedure as in "orientation starting during rotation". Note that if the current position signal is within the DC
injection brake start position, the spindle speed will not rise to the orientation speed and the DC injection
brake is applied.
