Input device explanation [A]
■SON (Servo-on)
If SON is turned on, the base circuit will be powered on and the servo amplifier will become in the operation-ready state
(servo-on state).
Once SON is turned off, the base circuit is shut off and the servo motor shaft coasts.
To change SON to "Automatic on" (always on) in the servo amplifier, set [Pr. PD01.0] to "4".
■RES (Reset)
Turn on RES for 50 ms or more to reset the alarm.
Some alarms cannot be deactivated by RES. Refer to the following for the alarms that cannot be deactivated.
MR-J5 User's Manual (Troubleshooting)
Turning RES on in an alarm-free state shuts off the base circuit. If [Pr. PD30.1] is set to "1", the base circuit will not shut off.
This device is not designed to make a stop. Do not turn it on during operation.
■TL (External torque limit selection)
When TL is off, [Pr. PA11] and [Pr. PA12] are enabled. When TL is on, TLA (Analog torque limit) is enabled.
