A parameter can be always used to set the servo ON condition. This eliminates the need to wire /S-ON,
but care must be taken because the servodrive can operate as soon as the power is turned ON.
4.3.2 Switching the Servomotor Rotation Direction
The rotation direction of the servomotor can be switched without changing the reference pulse to the
servodrive or the reference voltage polarity.
This causes the travel dir,-) of the shaft reverse. The output signal polarity such as encoder
pulse output and analog monitor signal from the servodrive does not change.
The standard setting for “forward rotation” is counterclockwise as viewed from the servomotor load end.

(Factory setting)
ON(low level)
Servomotor power ON. Servomotor can be
operated.
OFF(high level)
Servomotor power OFF. Servomotor cannot be
operated.
■Important
Always input the servo ON signal before inputting the input reference to start or stop the servomotor.
Do not input the input reference first and then use the /S-ON signal to start or stop. Doing so will
degrade internal elements and result to malfunction.
A parameter can be used to re-allocate the input connector number for the /S-ON signal. Refer to

b.□□□0
External S-ON signal enabled (Factory setting)
b.□□□1
External S-ON signal disabled, the servomotor excitation signal is
opened automatically after outputting the S-RDY signal.
·After changing these parameters, turn OFF the main circuit and control power supplies and then turn
them ON again to enable the new settings.
