Alarms
This driver is equipped with 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. The
PWR/ALM LED blinks in red simultaneously.
Details of the alarm being generated can be checked by counting the number of times the PWR/ALM LED blinks, via
EtherCAT communication, or using the
MEXE02
.

Alarm reset
Before resetting an alarm, always remove the cause of the alarm and ensure safety, and perform one of the reset
operations specified below.
•
Set the Fault reset (6040h: Bit 7) of Controlword to 1. (It is enabled when changing from 0 to 1.)
•
Turn the ALM-RST input ON. (It is enabled at the ON edge of the input.)
•
Execute the alarm reset using the
MEXE02
.
•
Turn off the main power supply and the control power supply, and on again.
•
Some alarms can be reset by only turning on the main power supply and control power supply
again. Refer to “1-4 Alarms list” on p.149.
•
An alarm of Absolute position error can be reset if the position preset (P-PRESET) or return-to-
home operation is performed. If it cannot be reset by these methods, the ABZO sensor may be
damaged.

•
Read the alarm history by the Alarm history (4041h to 404Ah) via EtherCAT communication.
•
Clear the alarm history by setting the Clear alarm history (40C2h) of EtherCAT communication to 1. (It is enabled
when changing from 0 to 1.)
