B.5 Trip codes
Version _AN
Trip codes appear on the upper line of the display.
Version _SL
The number given in brackets under each trip code (in the following list)
is the value that appears in parameter
10.20. This can be read via serial
communications.
User defined trips
A user-defined trip can be created by setting parameter 10.38 at 1 to 255
(but not 100) via serial communications. The value entered in 10.38 then
appears in
10.20;if10.38 is set at a value that corresponds with an
existing trip (e.g.
1), the cause of the trip will be interpreted accordingly
(e.g. if
1 is used, it will be interpreted as UU Insufficient DC-bus
voltage).
• Setting parameter
10.38 at 100 resets the Drive
• Setting parameter
10.38 to 255 resets the trip log
Trip
Code
Trip
No.
Description
UU
[1]
Insufficient DC-bus voltage.
This occurs when the AC supply is removed.
OU
[2]
Excessive DC-bus voltage.
Excessive regenerated power caused by the
following:
• Ramps not being used
•
0.26 Deceleration rate value too low
• Incorrect value of braking resistor
OI.AC
[3]
Excessive instantaneous output current caused by a
hardware fault.
OI.br
[4]
Excessive instantaneous current through the braking
transistor caused by the braking-resistor value being
tooloworashort-circuit.
PS
[5]
Internal power supply fault.
Remove and re-connect the AC supply. If the trip
persists, contact the supplier of the Drive.
Et
[6]
Parameter 10.38 has been set at 6 (via serial
communications) to indicate an
External trip.
Correct the cause of the trip and reset the Drive.
OU.SPd
[7]
The motor has exceeded the over-speed threshold.
Thiscanbecausedbythefollowing:
• Sudden removal of a large mechanical load
•
0.26 Deceleration rate value too low
• Inappropriate setting for
0.27 Fast ramp select

User-defined trips.
tunE1
[11]
The flux-alignment procedure has not changed the
position feedback.
tunE2
[12]
The flux-alignment procedure has not changed the
direction feedback.

User defined trips.
tunE
[18]
The flux-alignment procedure stopped before
completion.
It.br
[19]
Excessive braking duty-ratio.
Excessive value of [I
2
t] for the braking resistor.
I2t.AC
[20]
The motor current has not been sufficiently reduced
within the specified time after a motor thermal-
overload alarm (
OuL) has been produced by the
thermal-overload accumulator in the
SLM (see
Adjusting the threshold for the motor thermal-
overload alarm on page 105).
The Drive output becomes disabled.
O.ht1
[21]
The thermal model indicates excessive temperature
of the power stage of the Drive.
O.ht2
[22]
Excessive temperature detected by the Drive
heatsink thermistor.
O.ht3
[23]
Excessive SLM PCB temperature.
O.ht4
[24]
Excessive DC-bus capacitor temperature due to
excessive ripple current. To avoid shortening the life
of these capacitors, fit line reactors (see AC supply
disturbances – use of line reactors in Chapter 2 of the
Installation Guide).
tr25
[25]
User defined trip.
OP.OuL
[26]
The total current drawn from the digital outputs has
exceeded 400mA.

User defined trips.
SCL
[30]
Serial communications link error
EEF
[31]
Fault in the internal EEPROM, causing loss of
parameter values.
Follow the procedure in RestoringtheDrivetothe
default state on page 27, then re-enter the values for
the application.
Ph
[32]
Loss of an AC supply phase.

)
technology communications error caused by any
of the following:
• No 24V supply to the
SLM
• Faulty cable to the SLM
• Damaged SLM
dr.SI
[51]
Excessive mismatch between the current rating of the
motor and the Drive.
SL.Er
[52]
The value of parameter 10.52 indicates which of the
following has caused this trip.
[10.52]
Cause of the trip

No.
Description
CtC.Er
[53]
Ct-Coder error; contact the supplier of the Drive.
SL.InI
[54]
The SLM is being initialised (the trip code is seen
momentarily when the Drive is being powered-up)
Momentary display of the trip code does not cause
the Drive to trip.

the Drive.
