When zero clamping is used, the current speed must be less than zero clamping speed to make the motor shaft
clamped; When the zero clamping function is started, the motor changes from speed mode to position mode. At
this time, if the motor shaft is rotated and released again, it will return to its original position. However, when the
motor shaft is rotated in speed mode, it will not return to its original position because there is no position
feedback.
2. Input signal setting
Defaulted is not distribute to input
terminal
/Z-CLAMP signal is
distributed to input
terminal by parameter
P5-31, Range: 0000-0014.
Input signal from SI2 terminal
ZCLAMP input signal is ON, forced speed command is 0, when the speed
below P3-13, switch to position mode and the servo lock in this position.
ZCLAMP input signal is ON, forced set the speed command to 0.
ZCLAMP input signal is ON, the speed below P3-13, switch to position mode and the
servo lock in the position.
Note: after entering zero clamp mode, present setting speed is higher than
P3-13, motor doesn’t run, the ZCLAMP signal must be OFF, then motor
will run again.
ZCLAMP signal is ON, the setting speed is less than P3-13, switch to
position control mode, and servo is locked at this position. At this time, if
setting speed is over P3-13, the motor will run again.
