8 Warning and Alarm codes
Drive Display
Fault Code
Fault
Number
Description Corrective Action
Stop
0
Drive is healthy and in stop c
ondition. Motor is not energized. No enable signal is present to start drive
OI-b
1
Brake resistor over
current
Check cabling to the brake resistor and the brake resistor for short circuits.
Ensure the resistance of
the brake resistor is > minimum allow
ed value.
OL-br
2
Brake resistor thermal
overload.
Only occurs if P-34 = 1. The internal brake transistor software protection is
activated to prevent damage to the brake resistor.
If a standard braking resistor is being used, P-34 MUST be 1
Increase deceleration time in P-04, decrease load or speed
For Other Brake Resistors Ensure the resistance of the brake resistor is >
minimum allowed value. Use an external thermal protection and set P
-
34=2.
O-I
3
Instantaneous Over
current on the drive
output.
Excess load or shock
load on the motor.
Fault occurs immediately on drive enable or run command
Check the output wiring connections to the motor and the motor for short
circuits phase to phase and phase to earth.
Fault occurs during motor starting then check
 Motor is free to rotate and there are no mechanical blockages.
 If the motor has a brake fitted, check the brake is releasing correctly.
 Increase the acceleration time in P-03. Reduce the motor boost voltage P-11
Fault occurs when motor operating at constant speed
Investigate overload or malfunction.
I_trP
4
Motor thermal overload
protection trip. The
drive has tripped after
delivering >100% of
value in P-08 for a
period of time
 Ensure the correct motor nameplate current value is entered in P-08.
 Check for correct Star or Delta wiring.
 Check if decimal points are flashing (which indicates the output current > P-
08 value). Increase acceleration ramp (P-03) or decrease motor load. Check
the total motor cable length is within the drive specification. Check the load
mechanically to ensure that no jams, b
lockages or mechanical faults exist
.
PS-trP
5 Hardware Over Current
Check the wiring to motor for phase to phase and phase to earth short circuits.
Disconnect motor and cable. Retest. If the drive trips with no motor
connected, replace drive. Test for insulation failure.
O-Uolt
6
Over voltage on DC
bus
Check the supply voltage is within the allowed tolerance. If the fault occurs on
deceleration or stopping, increase the deceleration time in P-04 or install a
su
itable brake resistor and activate the dynamic braking function with P
-
34.
U-Uolt
7
Under voltage on DC
bus
Incoming supply voltage is too low. This trip occurs routinely when power is
removed from the drive. If it occurs during running, check the incoming
power supply voltage and all components in the power feed line to the drive.
O-t
8
Heat sink over
temperature
The drive is too hot. Check that ambient temperature around the drive is
within the specification. Ensure sufficient cooling air is free to circulate
around the drive. Increase the panel ventilation if required. Ensure sufficient
cooling air can enter the drive, and that the bottom entry and top exit vents are
not blocked.
U-t
9 Under temperature
Trip occurs when ambient temperature is less than -20°C. Temperature must
be raised over
-
20°C in order to start the drive.
P-dEf
10
Factory Default done
Press the STOP key, drive is ready to configure for particular application
E-trip
11
External trip E-trip requested on digital input 3. Normally closed contact has opened for
some reason. If motor thermistor is connected check if the motor is too hot.
SC-trp
12 Comms loss trip
Check communication link between drive and external devices. Make sure
each drive in the network has its unique address.
FLt-dc
13
DC bus ripple too high
Check incoming supply phases are all present and balanced
P-LOSS
14
Input phase loss trip
Drive intended for use with a 3 phase supply has lost one
input phase.
h O-I
15
Output Over Current
Check for short circuits on t
he motor and connection cable
Th-FlT
16
Temperature too high
Heat sink temperature too high, check adequate cooling air is provided
dAtA F
17
Internal memory fault.
Parameters not s
aved correct, defaults reloaded. Try again.
4-20 F
18
Analog input error
Analog input out of range. Check input current in range defined by P
-
16.
dAtA-E
19
Internal memory fault
DSP fault. Press the stop key. If the fault persists, consult you supplier.
F-Ptc
21
Motor thermistor trip
Connected motor thermistor over temper
ature, check wiring and motor
FAN-F
22
Cooling Fan Fault
Check / replace the cooling fan. Only IP66 drives
O-hEAt
23
Temperature too high
Drive ambient temperature too high, check a
dequate cooling air is provided
OUt-F
26 Fel efter utgångssteget
Internt fel i utgångssteg, en fas till motorn saknas, strömmen i alla tre faserna
till motorn ojämn. Kontrollera
