D. Manual Zero-Clamp Speed Control Mode
In case of which there is position control loop in host controller, it controls the position to
stop the motor. But if the host controller does not control the position when using the servo
drive only in speed control mode, speed command V-ref is not completely 0[V], and little
offset may exist. Here, motor rotates little and uses this function to completely stop the
motor rotation.

clamp control mode. Motor may not operate correctly.
Warning
Also, set acceleration/deceleration time to "0".
• Parameter and input terminal related to zero-clamp is as follows.

ON: The corresponding input terminal is connected to input voltage GND (0V)
OFF: The corresponding input terminal is connected to +24VIN it is not connected
Motor can rotate
little by little due
to the offset
