Alarm reset [RST]: Sequence input signal (Reference value 11)
The alarm reset signal resets alarm detection of the servo amplifier.

Function
The sequence input signal resets alarm detection of the servo amplifier.
The rising edge of the alarm reset [RST] signal resets alarm detection.
By starting the test operation mode at the keypad, operating the PC Loader or turning the power
on again, the alarm can be reset.
 Parameter setting
To assign the alarm reset [RST] signal to a sequence input terminal, specify the corresponding
value ("11") to the input terminal function setting parameter.
 Relevant description
There are the following methods for resetting alarm detection.

Rising edge of alarm reset [RST] of sequence input signal

Press and hold the [SET/SHIFT] key for at least one second in the test operation mode [
Fn05
].

Press and hold the [

] and [

] keys simultaneously for at least one second upon alarm detection
[
En01
].

Alarm reset from PC Loader

Shutdown and power-on again
