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.

In case of operating position control in the host control-
ler, do not use zero-clamp control mode. Motor may not
operate correctly.
Also, set acceleration/deceleration time to "0".
