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 ; if 10.38 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
too low or a short-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.
This can be caused by the following:
•
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.
tr13 ~
tr17
[13~
17]
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.
tr27 ~
tr29 [27~
29]
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 Restoring the Drive to the
default state on page 27, then re-enter the values for
the application.
Ph
[32] Loss of an AC supply phase.
tr33 ~
tr49 [33~
49]
User defined trips.
dL.Er
[50]
)
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
0 dL.Er trip has occured before SL.Er trip
1 ENCODER OBJECT CRC checksum incorrect
2 MOTOR OBJECT CRC checksum incorrect
4 EZE OBJECT CRC checksum incorrect

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.
In.An9
[55]
Initial mismatch from the SLM ; contact the supplier of
the Drive.
