Setting
Use the following parameter to set the motor speed level at which zero clamp is per-
formed.
Parameter
Pn501
Zero Clamp Level
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 (0V).
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
function ON and OFF.
