5.3.4 Alarm history clear
The servo amplifier stores six past alarms from when its power is switched on first. To control alarms which will
occur during operation, clear the alarm history using parameter No.PC21 before starting operation.
Clearing the alarm history automatically returns to "
0".
After setting, this parameter is made valid by switch power from OFF to ON.
