Notifying that the detected speed has become zero: ZV output
The ZV output can be enabled by selecting the output using the application parameter for output signal
selection 2 [APP-1-03]. When the detected speed drops into the zero speed output band, the ZV output will
turn ON.
You can set the band within which the ZV output turns ON, using the application parameter for zero speed
output band [APP-1-06].

Freeing the motor output shaft: FREE input
When the FREE input is turned ON, the motor current will be cut off. The motor will lose its holding torque,
and the output shaft can be turned with an external force. The deviation counter will also be cleared.
If the FREE input is turned ON while the position is held with the electromagnetic brake, the electromagnetic
brake will be released. Accordingly, the position can no longer be held.
