Table 9-13 Trip indications
No. String Cause of trip
1 UU DC bus under voltage
2OU
DC bus over voltage.
Drive voltage rating Instantaneous trip
200V 415V
400V 830V
3 OI.AC AC instantaneous over current.
4 OI.br Braking resistor instantaneous current trip.
6 Et External trip (see Pr 10.32 on page 111)
7 O.SPd Overspeed
18 tunE Auto-tune stopped before completion (see Pr 5.12 on page 60)
19 It.br
I
2
t on braking resistor (see Pr 10.31 on page 110)
20 It.AC
I
2
t on drive output current (see Pr 4.15 on page 51)
21 O.ht1 Drive over-heat (IGBT junctions) based on thermal model (see Pr 5.18 on page 63)
22 O.ht2 Drive over-heat based on heatsink temperature (see Pr 7.04 on page 82)
24 th Motor thermistor trip
26 O.Ld1 +24V or Digital output overload
27 O.ht3
Drive over-heat based on thermal model (see Pr 7.35 on page 86)
The drive will attempt to stop the motor before tripping. If the motor does not stop in 10 seconds the drive trips
immediately.
28 cL1 Analog input 1 current mode: current loss (see Pr 7.06 on page 82)
30 SCL Serial comms timeout with external keypad on drives comms port
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 (see Pr 11.43 on page 124)
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.
33 rS
Failure to measure resistance during auto-tune or when starting in open-loop voltage modes 0 or 3. This is either because
the resistance exceeds the maximum measurable value or no motor connected to drive (see Pr 5.12 on page 60, Pr 5.14
and Pr 5.17 on page 62)
35 CL.bt Trip initiated from the control word (see Pr 6.42 on page 78)
40-89
t040 -
t089
User trips
90 t090 Drive user program error - divide by zero
91 t091 Drive user program error - parameter does not exist
92 t092 Drive user program error - parameter is read only
93 t093 Drive user program error - parameter write over range
94 t094 Drive user program error - virtual memory stack overflow
95 t095 Drive user program error - LogicStick removed
96 t096 Drive user program error - invalid operating system call
97 t097 Drive user program error - invalid instruction
98 t098 Drive user program error - invalid function block argument
99 t099 User trip
100 Drive reset (see Pr 10.38 on page 112)
182 C.Err
Card data error:
The file access is corrupted.
Pr 11.42 is set to 3 or 4 and a parameter is changed in menu 0 before reset is activated.
183 C.dAt
Data does not exist:
An attempt has been made to transfer data from a blank card or data block that does not exist.
185 C.Acc
Card read/write fail:
The drive cannot communicate with the card either because it is faulty or is not fitted in the drive. Removing a card during
an access will cause this trip.
186 C.rtg
Rating change:
The parameters loaded to the drive from a card are for a drive of a different voltage or current rating. No rating dependent
parameters have been transferred.
189 O.cL Overload on current loop input
199 dESt Destination parameter clash
200 Sl.HF
Option module hardware fault. This could occur because the module cannot be identified, or the module has not indicated
it is running within 5s of drive power-up, or an internal hardware fault has occurred in the module.
201 Sl.tO
Option module watchdog timeout. The module has started the watchdog system, but has not subsequently serviced the
watchdog within the timeout period.
202 Sl.Er Option module error. The module has detected an error and tripped the drive. The reason for the error is stored in Pr 15.50
