5-5-6. Speed coincidence checking (/V-CMP)
When motor speed is equal to the command speed, servo outputs speed coincidence signal
(V-CMP).

Range: 0000-0013. Distribute to output
terminal through P5-29. When it set to
0002, it means output from SO2.
5-5-7. Torque limit
5-5-7-1. Internal torque limit (output torque max value limit)
The function is to limit the max output torque by parameters.

1. This parameter is always effective, if this parameter value is less than external torque limit value, the
final limit value is this parameter.
2. The unit is percent of the motor rated torque; the default value is 300%. The real output torque is
different for each type.
5-5-7-2. External torque limit (via input signal)
This function is used in machine motion or timing torque limit. For example: press stop
action or robot workpiece protection.
Zero clamp will act when meets the following conditions:
