Condition 1: /P-CON (/ZCLAMP) is
ON.

V (ON).
Turns the

Speed Control
Set the motor speed at which zero clamp is performed if zero clamp speed control is selected.
Even if this value is set higher than the maximum speed of the Servomotor, the maximum speed
will be used.
Zero Clamp Conditions
Zero clamp is performed when all the following conditions are satisfied:
D
Zero clamp speed control is selected (user constant Pn000.1 is set to A).
D
/P-CON (/ZCLAMP)(CN1-41) is ON (0 V).
D
Speed reference drops below the setting of Pn501.
