8 ZERO POINT RETURN CONTROL
Restrictions
A pulse generator with a zero point signal is required.
When using a pulse generator without a zero point signal, generate a zero point
signal using an external signal.
Precautions during operation
(1) An error "Start at zero point" (error code: 201) will occur if another machine
zero point return is attempted after a machine zero point return completion
when the zero point return retry function is not set ("0" is set in " Pr.50 Zero
point return retry").
(2) Machine zero point returns carried out from the near-point dog ON position will
start at the " Pr.49 Creep speed".
(3) The near-point dog must be ON during deceleration from the zero point return
speed " Pr.49 Creep speed".
(4) If the restart command is turned ON after machine zero point return is stopped
upon a stop signal, an error “zero point return restart not possible” (error code:
209) occurs.
