Exciting the motor: S-ON input
This input is effective when the parameter for operation selection after stopping in speed control mode
[SyS-1-02] is set to “Servo lock.”
Turning the S-ON input ON will excite the motor. In the case of an electromagnetic brake motor, the
electromagnetic brake will be released after the motor is excited.
When the S-ON input is OFF, the deviation counter will be cleared and input operation commands will be
ignored.
You can set the S-ON input to function in the contact A (normally open) or B (normally closed) logic using
the application parameter for S-ON signal logic [APP-1-00] (the initial value is to use the contact A logic
(normally open)). If the S-ON input is set to use the contact B (normally closed) logic, the motor will be
excited automatically after the power is turned on and turning the S-ON input ON will cause the motor to lose
its holding torque.
Note
If the S-ON input is turned ON when only the 24 VDC power is input, a main power supply
warning will generate. If a pulse signal is input while a main power supply warning is
present, a main power supply error will generate.

Stopping the motor instantaneously: BRAKE input
The motor can be stopped instantaneously by turning the BRAKE input OFF. To operate the motor, turn the
BRAKE input ON.
If the application parameter for BRAKE signal logic [APP-1-01] is set to “Contact A (normally open),” the
motor will stop instantaneously when the BRAKE input turns ON.
