This section lists the alarm/warning codes and error codes for message communications.
Alarm codes are displayed on the front of the W-series Servo Driver and, at the same time,
can also be read as responses at the host device connected via DeviceNet. Alarms are also
displayed using the MS and NS indicators on the DeviceNet Unit.
The MS indicator is the module status; the NS indicator is the network status. The required
indicator responses are shown in the table.
The alarm codes are shown below.

Alarm Name
EEPROM data of Servo Driver is abnormal.
Detection data for power circuit is abnormal.
The parameter setting is out of the allowable set-
ting range.
Servo Driver and Servomotor capacities do not
match each other.
An overcurrent flowed through the IGBT.
Heat sink of Servo Driver was overheated.
• Regenerative resistor is disconnected.
• Regenerative transistor is defective.
Regenerative energy exceeds regenerative resis-
tor capacity.
The AC/DC wiring method of the main circuit
power supply is different from the setting of the
parameter Pn001.2 (Power Supply AC/DC Input
Selection).
Main circuit DC voltage is excessively high.
Main circuit DC voltage is low.
Rotational speed of the motor is excessively
high.
The motor was operating for several seconds to
several tens of seconds under a torque largely
exceeding ratings.
The motor was operating continuously under a
torque largely exceeding rating.
When the dynamic brake was applied, rotational
energy exceeded the capacity of dynamic brake
resistor.
The main circuit power was frequently turned
ON and OFF.
