10.3 Fault list
The following table lists the DE1 variable speed starter's fault messages, as
well as possible causes and fixes:
•
Fault Code
LED (2 Hz + 2 s) = Number of flashing pulses plus
a 2-second pause
•
Modbus RTU [hex] = Hexadecimal fault code via Modbus
•
DX-KEY-LED display = Fault code on the optional DX-KEY-LED keypad's
7-digital display assembly

I.t-trP
Thermal motor overload
• If the decimal points are flashing or OL is displayed on an
external keypad, this means that the motor current set in
P-08 has been exceeded. The device will be switched off
after a time of more than 100% (I
2
t value).
→
Reduce the motor load or increase the acceleration time
(P-03).
→
Check the current specifications on the motor's rating
plate and the value in P-08, as well as the motor's
configuration (wye, delta).
2 x
0B
E-triP
External fault message
• The control voltage (HIGH level) at terminal 3 (DI3) has been
switched off and the terminal is configured with the EXTFLT
(P-15 = 1, 3, 5, 7, 9) function.
→
Check the motor's temperature or the external sensors
if a thermistor is connected with this configuration.
3 x
06
O.Volt
Overvoltage
• Overvoltage in DC link
→
Check the mains-side supply voltage's magnitude.
→
If the fault message occurs during braking, this means
that the regenerative energy is too high. In this case,
increase the deceleration time (P-04).
4 x
02
O-I
Overcurrent
• Fault message immediately after enable signal or start
command
→
Check the motor connection for line-to-line or earth
faults.
• Fault message during start phase:
→
Check whether the motor can rotate freely (blocked,
mechanical brake).
→
Check the motor's configuration (star, delta).
→
Increase acceleration time P-03.
→
Lower start voltage P-11.
• Fault message during constant speed
→
Check the drive for overload (shock load) or malfunction.
• Fault message during speed change
→
Check the drive for oscillating loads (e.g., in the case of
pumps and fans).
5 x
08
O-t
Overtemperature
• Overtemperature at internal heat sink
Please check the following:
→
Does the ambient temperature meet specifications?
→
Is there enough air circulation around the DE1 variable
speed starter (clearances above and underneath)?
→
Are the vents clear?
→
In the case of devices with an internal fan: Is the fan
running?
