Sub-trip Reason
1 The most significant digit of the internal parameter database version number has changed.
2 The CRC's applied to the parameter data stored in internal non-volatile memory indicate that a
valid set of parameters cannot be loaded.
3 The drive mode restored from internal non-volatile memory is outside the allowed range for the
product or the derivative image does not allow the previous drive mode.
4 The drive derivative image has been changed and it has changed the customisation of the drive
core menus.
5 The power stage hardware has been change and changed the customisation of the drive core
menus.
6 The internal I/O hardware has been change and changed the customisation of the drive core
menus.
7 The position feedback interface hardware has been change and changed the customisation of the
drive core menus.
8 The control board hardware has been change and changed the customisation of the drive core
menus.
9 The checksum on the non-parameter area of the EEPROM has failed.
The drive holds two banks of user save parameters and two banks of power down save parameters in non-volatile memory. If the last bank of either set of
parameters that was saved is corrupted a User Save or Power Down Save trip is produced. If one of these trips occurs the parameters values that were last saved
successfully are used. It can take some time to save parameters when requested by the user and if the power is removed from the drive during this process it is
possible to corrupt the data in the non-volatile memory.
If both banks of user save parameters or both banks of power down save parameters are corrupted or one of the other conditions given in the table above
occurs EEPROM Fail.xxx trip is produced. If this trip occurs it is not possible to use the data that has been saved previously, and so the drive will be in lowest
allowed drive mode with default parameters. The trip can only be reset if Parameter mm.000 (mm.000) is set to 10, 11, 1233 or 1244 or if Load Defaults (11.043) is
set to a non-zero value.
Recommended actions:
Default the drive and perform a drive reset.
Allow sufficient time to perform a save before the supply to the drive is removed.
If the trip persists, return drive to the supplier.
Trip Encoder 1
Value 189
Short description
Drive position feedback interface power supply overloaded. Terminals 13 & 14 of the 15 way D-type connector can supply a maximum current of 200mA at 15V or
300mA at 5V.
Recommended actions:
Check encoder power supply wiring.
Disable the termination resistors (P1 Termination Select (03.039) set to 0) to reduce current consumption.
For 5V encoders with long cables, select 8V (P1 Supply Voltage (03.036)) and fit a 5V voltage regulator close to the encoder.
Check the encoder specification to confirm it is compatible with the encoder port power supply current capability.
Replace the encoder.
Use an external power supply with higher current capability.
Trip Encoder 2
Value 190
Short description
There is a wire break between the drive and the position feedback device. These trips are provided for the P1 position feedback interface only and the exact cause
of the trip can be identified from the sub-trip number as given below.
Sub-trip Signals
1 Resolver or SINCOS sine wave signals
11 Digital incremental A signal
12 Digital incremental B signal
13 Digital incremental Z signal
14 SC SC device single turn sine wave commutation signals.
15 SC SC device marker
This trip can occur if the position feedback device type selected in P1 Device Type (03.038) is not correct for the position feedback device connected to the drive.
