Parameter Setting
Set the following parameter to A so that the input signal /P-CON
(/ZCLAMP) can be used to enable or disable the zero clamp function.

Zero Clamp Control Mode
This mode allows the zero clamp function
to be set when the servomotor stops.
•
The speed reference is input from V-
REF (CN1–5).
•
/P-CON (/ZCLAMP)(CN1–41) is used
to turn the zero clamp function ON and
OFF.
CN1-41 is open (OFF).
Turns the zero clamp function OFF.
CN1-41 is 0 V (ON).
Turns the zero clamp function ON.
Zero clamp is performed when the following
two conditions are satisfied:
•
/P-CON (/ZCLAMP) is ON.
•
Speed reference is below the setting
designated at Pn501.
Setting Motor Speed
Use the following parameter to set the motor speed level at which zero
clamp is performed

Level
Range: 0 to 10000
Default Setting: 10
Speed Control
If zero clamp speed control is selected, set the motor speed at which zero
clamp is to be performed. The maximum speed will be used if the value of
Pn501 is set higher than the maximum speed of the servomotor.
Zero Clamp Conditions
Zero clamp is performed when all the following conditions are satisfied:
• Zero clamp speed control is selected (parameter Pn000.1 is set to A).
• /P-CON (/ZCLAMP)(CN1-41) is ON (0 V).
• Speed reference drops below the setting level of Pn501.
