7.1 OPERATION OF FAULTS AND ALARMS
When “ALARM” (AXXXXX) is identified:
The HMI indicates the numeric code of the alarm.
The servo drive remains in operation, without blocking the PWM pulses.
The code of the “ALARM” occurred is saved, as well as related information (date, time, etc.).
When “FAULT” (FXXXXX) is identified:
The PWM pulses are blocked.
The HMI indicates the numeric code of the fault.
Red LED “FAULT” turns on.
The relay that is programmed for “NO FAULTS” is turned off.
The code of the “FAULT” occurred is saved, as well as related information (date, time, etc.).
For the servo drive to go back to normal operation right after the occurrence of a "FAULT", it is necessary to reset
it. Below are some options of reset:
Turn off the power supply of the control and turn it on again (power-on reset).
Press the RESET key.
Modify the value of parameter P00219 from 0 to 1 (leading edge).
Via digital input: DIx = 6.
