„ Setting
Use the following parameter to set the motor speed level at which zero clamp is performed.
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:
• Zero clamp speed control is selected (parameter Pn000.1 is set to A).
• /P-CON (/ZCLAMP)(CN1-41) is ON (0V).
• Speed reference drops below the setting of Pn501.
When the /ZCLAMP signal is allocated, the zero clamp operation will be used even for speed control
(Pn000.1 = 0).

Setting
Control Mode
A Zero Clamp Control Mode
This mode allows the zero clamp
function to be set when the servomo-
tor stops.
• The speed reference is input from
V-REF (CN1-5).
• /P-CON (/ZCLAMP)(CN1-41) is
used to turn the zero clamp func-
tion ON and OFF.
Zero clamp is performed when the fol-
lowing two conditions are satisfied:
Condition 1: /P-CON (/ZCLAMP) is
ON.
Condition 2: Speed reference is below
the setting at Pn501.
CN1-41 is
open (OFF). Turns the
zero clamp
function
OFF.
CN1-41 is
0 V (ON). Turns the
zero clamp
function ON.
