What this chapter contains
This chapter lists the DriveConfig PC tool error messages.
ACS55
The fault messages received from the ACS55 drive are also displayed in
DriveConfig. The ACS55-related fault messages are listed in the following table.

Possible causes and what to do
#
Possible causes and what to do
1
DC overvoltage. 1) Mains voltage is too high:
Check supply. 2) Deceleration ramp time is too
short compared to the load inertia: Increase
ACC/DEC time with potentiometer.
7
Motor overload (I
2
t overload): 1) Check the load, and verify
that the motor size is suitable for ACS55. 2) Verify that
setting of MOTOR I NOM potentiometer is correct. See
chapter ACS55 motor overload protection on page 53.
2
DC undervoltage. Mains voltage is too low:
Check supply.
8
Inverter overload or excessive internal temperature: 1)
Load is too high or 2) drive cooling is insufficient.
3
Output short circuit: Switch off the power and
check the motor windings and motor cable.
9
Other fault. Internal error. Turn power off and on again. If
problem persists, replace the unit.
4
Output overcurrent. 1) Acceleration time is too
short compared to the load inertia: Increase
ACC/DEC time with potentiometer. 2) Motor
and drive sizes do not match: Check motor.
10
Parameterization fault. Note: Both LEDs will blink. DIP
switches have been moved from default setting after the
drive has been parameterized with DriveConfig tool. Put
the switches back to default position.
5
Reserved
11
Drive is battery-powered. Drive status indicates Fault,
because it is not possible to start the drive. For drive
operation, the drive must be connected to mains. However,
when the drive is powered from the DriveConfig kit supply,
the connection between DriveConfig and the drive is OK.
6
Analogue input value is less than 4 mA / 2 V.
Note: This supervision is active if AI OFFSET
is ON.
12
Drive has been controlled by DriveConfig (or other
application via serial communication) and the
communication has been lost. Check the communication.
