Form an external circuit so that the servo amplifier turns OFF when an
alarm occurs. Alarms are reset automatically when the control power
supply is turned OFF.
Alarms can also be reset using a panel or digital operator.
Note: 1. Encoder alarms cannot always be reset by inputting the /ALM-RST signal. In that case, turn the
control power supply OFF to reset the alarm.
2. When an alarm occurs, always eliminate the cause before resetting the alarm. See 9.2.1
Troubleshooting Problems with Alarm Displays for more details on troubleshooting the system when an
alarm occurs.
3. In a Position Control Alarm Code do not relate to trajectory errors.
5.5.2. Using the Servo ON Input Signal (/S-ON)
This section describes the basic use and wiring procedure for the Servo
ON (/S-ON) input signal (sequence input signal). Use this signal to
forcibly turn OFF the servomotor from the host controller.
î›– Input /S-ON CN1-40 Servo ON
Speed/Torque Control, Position
Control
This signal is used to turn the servomotor ON and OFF.
CN1-40 State Status Result
ON Closed or low level
Turns ON the servomotor: operates
according to signal input.
This is the default state.
OFF Open or high level
Servomotor cannot operate.
Do not turn OFF the servomotor while it is
operating except in an emergency.
CAUTION
•
Do not use the Servo ON (/S-ON) signal to start or stop the motor. Always use an input
reference signal, such as Speed Reference to start or stop the servomotor.
Using the Servo ON signal to start or stop the motor will shorten the life of the servo
amplifier.
Set the following parameter to 7 if the /S-ON signal will not be used.
