Note
• The zero return command is not accepted if the zero-point pass signal servo status is OFF.
Before executing zero return, be sure to rotate the servomotor at least once to turn the zero-point pass
signal ON. The zero-point pass signal turns ON when the motor passes the motor reference position signal
(Z-phase).
To execute zero return immediately after power-on, specify "1: Motor Z-phase pass unnecessary after
power-on" (default setting) at servo parameter function selection C-4. With this setting, the zero-point pass
signal turns ON even if the motor does not pass the zero-point (Z-phase).
• With the simultaneous start flag ON, the X-axis mechanical zero return command simultaneously starts the
X and Y-axes mechanical zero return operation.
(The 20SSC-H ignores the Y-axis mechanical zero return command.)
DOG position
Install the DOG at a position far enough from the stopper for the work piece to decelerate to the zero-point
return speed (creep).
2. Changing the zero return speed
Use the override function or operation speed change function to change the zero return speed (high speed).
However, the speed does not change when the operation speed change disable flag is ON.
