A 0 to 1 change on this parameter will cause a drive reset. If a drive reset terminal is required on the drive the required terminal must be
programmed to control this bit. Digital input 6 is defaulted to reset function.
No. String Cause of trip
1 UU DC link under voltage
2OU
DC link over voltage. This could be because the DC link voltage has exceeded the maximum level
or has remained above the maximum continuous level for more than 30s.
Drive voltage rating: 400V
Instantaneous trip: 830V
Max continuous level: 810V
3 OI.AC AC instantaneous over current, caused by hardware fault, this trip cannot be reset for 2s
4 OI.br Braking resistor instantaneous current trip. This trip cannot be reset for 2s.
5 PS Internal drive power supply trip
6EtExternaltrip
7 OU.SPd Over speed (see [3.08])
8 ~ 10 tr08 ~ tr10 User trips
11 tunE1 No axis movement, during Flux alignment procedure.
12 tunE2 Incorrect direction of rotation, during Flux alignment procedure
13 ~ 17 tr13 ~ tr17 User trips
18 tunE Flux alignment procedure stops before completion
19 It.br Braking resistor over-heat based on thermal model. (see [10.39])
20 I2t.AC Motor over-heat based on thermal model (see [10.58])
21 O.ht1 Drive over-heat based on thermal model (see [10.56])
22 O.ht2 Drive over-heat based on heat sink temperature (see [7.04])
23 O.ht3 SLM over-heat based on PCB temperature (see [10.59])
24 O.ht4 SLM over-heat based on PCB temperature (see [10.59])
25 tr25 User trips
26 OP.Oul Digital output overload
27 ~ 29 tr27 ~ tr29 User trips
31 EEF
Internal drive EEPROM failure. All the parameters are set to default. The trip can only be removed
by entering a load default command (i.e. 1233,1244,1255 etc.) into parameter [x.00]before
resetting the drive.
32 Ph
High input voltage phase imbalance or input phase loss. Normally a motor load of between 50 and
100% or drive rating is required to trigger the trip. The drive will attempt to stop the motor before
tripping, if specified in parameter [10.54].
33 ~ 49 tr33 ~ tr49 User trips
50 dL.Er
DrivelinK hardware error. Possibly due to:
• No 24v supply to SLM
• Faulty cable
• DamagedSLM/driveRS485driversduetoexcessiveESD
51 dR.SI Motor / drive excessive current rating mismatch
52 SL.Er See parameter 10.52 for explanation
53 CtC.Er
Encodererrorcause:
• Quadrant mismatch
• Initialisation failure
54 SL.Er
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.
55 In.An9 Initial mismatch from the SLM; contact the supplier of the drive.
56 ~ 99 tr56 ~ tr99 User trips

101 ~ 254 tr101 ~ tr254 User trips
