Alarms
This driver has the alarm function to protect from temperature rise, poor connection, error in operation, and others.
If an alarm is generated, the ALM-A output is turned ON and the ALM-B output is turned OFF to stop the motor. At the
same time, the PWR/ALM LED blinks in red.
Details of the alarm being generated can be checked by counting the number of times the PWR/ALM LED blinks, or
using PROFINET or the
MEXE02
.
