CHAPTER 2 WIRING
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
2
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].
