5.3.4 Alarm history clear
The driver stores past six alarms since the power is switched on for the first time. To control alarms which will
occur during the operation, clear the alarm history using parameter No.PC18 before starting the operation.
Turn off the power and then on again after setting the parameter to validate the parameter value.
Clearing the alarm history automatically returns to "
0 ".
After setting, this parameter is made valid by switch power from OFF to ON.
