Zero phase passed
Function selection C-4
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.)
