Inspection and Protection Function
CSD7 Servo Drive (EtherCAT)
Servo Fault
The servo fault is a serious problem. It occurs when the servo drive
cannot control motor normaly. When the fault occurs, 3-digit fault
code and 5-digit text message as shown in the below table are
displayed by turns.

Possible Cause Countermeasures
E.005
IPM Fault
E.IPMFt 0x5400 0x11
Motor cable is shorted
 Check if the motor power cable or
the connector is shorted.
It occurs when the motor coil is
shorted internally.
 Disconnect the motor power cable
from the motor. If the motor can
not be rotated by hand, a
replacement may be needed.
It o
ccurs when the current exceed
the continuous power rating while
operating.

Check if the ambient temperature
is too high.

Operate within the continuous
power rating.

Decrease the acceleration and the
deceleration rate.
It o
ccurs when an unsuitable IPM
output, short circuit or over
current exist in the drive.
 Check the wiring connections that
go from the DC bus to U, V, and
W terminal of motor after
disconnecting the all power cable
and the motor.
 If the connections are normal,
check the wires between terminals
or repaire the drive.
It occurs when the operation
voltage of IPM in drive is low

Check if the IP16V power on the
power board is 15 V or above.
E.006
FAN Fault
E.FAn 0x3330 0x43
Fan attached on servo drive work
abnormally.
 Check whether there are foreign
substance on the fan blade, and
remove it.
 Check whether the fan cable is
connected to the servo drive
properly.
E.009
DC Bus Low-
voltage
E.UdvtG 0x3220 0x41
The AC input voltage is low.
(This alarm occurs when the DC
link bus voltage drops below 190V
and lasts for over 1msec in servo-
ON state.)

Check the voltage level of AC
power supply. (should be more
than AC 170V)

Check the noise or voltage drop of
AC power source.
 Install a UPS (Uninterruptible
Power Supply) in AC inputs.
The AC input voltage is normal,
however the DC link voltage was
low due to excessive use of
 Reduce the motor acceleration.
