*The enable/reset terminal will not reset an O.Ld1 trip. Use the stop/reset key.
**These trips cannot be reset for 10 seconds.
***The UV trip is only stored in the drive’s trip log if the drive trips on UV while running.
Trips can be grouped into the following categories:
Table 10-18 Under voltage trip and restart levels
* These are the absolute minimum dc voltages that the drive can be supplied by.
202 SL.Er
Solutions Module error. The module has detected an error and tripped the drive. The reason for the error is stored in Pr
15.50
203 SL.nF
Solutions Module not installed. The Solutions Module is identified by the drive by an option code. The drive stores the
codes of the modules installed when the drive parameters are saved. The stored codes are compared with the codes from
the Solutions Modules at power-up. If a module is not present, but a code is stored in drive EEPROM to indicate that it
should be installed the drive trips. If the module is removed after power-up the drive produces this trip within 4ms.
204 SL.dF
Solutions Module different installed. The Solutions Module is identified by the drive by an option code. The drive stores the
codes of the modules installed when the drive parameters are saved. The stored codes are compared with the codes from
the Solutions Modules at power-up. If a module is different to the code stored in drive EEPROM the drive trips.
220 to
232
HF20 - HF32 Hardware faults (See table Table 10-19 HF trips )
Category Trips Comments
Hardware faults HF01 to HF19
These indicate fatal problems and cannot be reset. The drive is inactive after one
of these trips and the display shows HFxx. The serial communications is inactive
and the parameters cannot be accessed.
Self resetting trips UV
Under voltage trip cannot be reset by the user, but is automatically reset by the
drive when the supply voltage is within specification (See table Table 10-
18 Under voltage trip and restart levels )
Non-resetable trips HF20 to HF32, SL.HF
Cannot be reset. The serial communications is active and parameters can be
accessed.
EEF trip EEF Cannot be reset unless a default parameter set has been loaded.
Normal trips All other trips Can be reset after 1.0s
Normal trips with extended
reset
OI.AC, OI.br Can be reset after 10.0s
Low priority trips O.Ld1, cL1, SCL If Pr 10.37 is 1 or 3 the drive will stop before tripping.
Phase loss PH
The drive stops before tripping provided the drive motoring power is suitably
reduced after 500ms of detecting phase loss
