SCL
|
Serial comms timeout with remote keypad
on drive 485 comms port
|
|
31
|
EEF
|
Internal drive EEPROM checksum. See trips 36 and
37 below. When this trip occurs the drive mode becomes Open-loop and all the
parameters are set to default. The trip can only be removed by entering a
load default command (i.e. 1233, 1244, etc.) into parameter x.00
before reseting 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 except in Regen mode. This trip is initiated when phase loss is
detected from d.c. link ripple.
|
|
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 the drive was not enabled
(see 05.12, 05.14, 05.17)
|
|
34
|
Pad
|
If an LED or LCD keypad are fitted directly to the
drive, and the drive is in keypad reference mode, and the keypad is removed
the drive produces this trip.
|
|
35
|
CL.bit
|
Trip initiated from the control word (parameter
06.42)
|
|
36
|
SAVE.Er
|
The drive holds two banks of user save parameters
in EEPROM. This trip indicates that the power was removed when parameters
were being saved which resulted in an error in a user save parameter bank.
The drive will revert back to the user save parameters that were last saved
successfully. If errors occur in both banks an EEF trip is initiated. This
trip will occur on every subsequent power up until parameters are saved
again.
|
|
37
|
PSAVE.Er
|
Power down save parameters are saved during power
down and can be saved when user parameters are saved. The drive holds two
banks of power down save parameters in EEPROM. This trip indicates that the
power was removed when parameters were being saved which resulted in an error
in a power down save parameter bank. The drive will revert back to the power
down save parameters that were last saved successfully. If errors occur in
both banks an EEF trip is initiated. This trip will occur on every subsequent
power up until power down save parameters are saved again (i.e. a power down
on a normal supply or a parameter save is initiated by the user).

the alignment of the analogue signals of a SINCOS encoder with the digital

Data error from electronic nameplate data stored
in selected position feedback device.
|
|
177
|
C.Boot
|
A write to a menu 0 parameter has been initiated
via the keypad by exiting edit mode and parameter 11.42 is set for auto or
boot mode, but the necessary boot file has not been created on the SMART card
to take the new parameter value. This occurs when 11.42 is changed to auto or
boot mode, but the drive is not subsequently reset.
|
|
178
|
C.BUSy
|
An attempt has been made to access a SMART card,
but the SMART card is already being accessed by an option module.
|
|
179
|
C.Chg
|
An attempt has been made to store a data in a
SMART card data block which already exists.
|
|
180
|
C.Optn
|
Parameter data or default difference data is being
transferred from a SMART card to the drive, but the option module categories
are different between source and destination drives. This trip does not stop
the data transfer, but is a warning that the data for the option modules that
are different will be set to the default values and not the values from the
card.
|
|
This trip also applies if a compare is attempted
between the data block and the drive.
|
|
181
|
C.RdO
|
An attempt has been made to modify a read-only
SMART card (i.e. erase the card, erase a file or create a file). A SMART card
is read-only if the read-only flag has been set or the card contains data
blocks with numbers from 500 to 999. Attempting to create data blocks with
numbers from 500 to 999 will always cause a trip.
|
|
182
|
C.Err
|
An attempt has been made to transfer a data block
from a SMART card to the drive or to compare a SMART card data block and the
checksum is incorrect or the data structure on the card is incorrect.
|
|
183
|
C.dat
|
An attempt has been made to transfer a data block
from a SMART card to the drive or to compare a SMART card data block and the
block does not exist.
|
|
184
|
C.FULL
|
An attempt has been made to create a data block on
a SMART card, but there is not enough space on the card.
|
|
185
|
C.Acc
|
An attempt has been made to access a SMART card,
but a card is not present or communications failure has occurred between the
drive and the card. This trip is also produced if an attempt is made to
access a data block that has already been opened by an option module.
|
|
186
|
C.rtg
|
Parameter data or default difference data is being
transferred from a SMART card to the drive, but the current and /or voltage
ratings are different between source and destination drives. This trip does
not stop the data transfer, but is a warning that the data for the option
modules that are different will be set to the default values and not the
values from the card.
|
|
This trip also applies if a compare is attempted
between the data block and the drive.
|
|
187
|
C.Typ
|
This trip is produced during a compare if the
drive mode in the data block is different from the current drive mode and the
file is a parameter or defaults differences file. This trip is also produced
if an attempt is made to transfer parameters from a parameter or default
difference to the drive if the drive mode in the data block is outside the
allowed range of drive modes for the drive.
|
|
188
|
C.cpr
|
A compare has been carried out between a data
block on a SMART card and the drive and the compare has failed. This trip
only occurs if the compare has not already failed with the following
trips: C.Typ, C.rtg, C.Optn, C.BUSy, C.Acc or C.Err

because the encoder type parameter 03.38 has been changed,
but initialisation has not occurred, or
the initialisation process has failed due to encoder comms failure.)

EnC8
|
Drive encoder trip: Auto-configuration failed.
(Auto-configuration has been requested by changing parameter 03.41, but
an initialisation has not occurred to perform auto-configuration.)

SL1.HF
|
Option module in slot 1: 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. If the module is removed after power-up the
drive also produces this trip.

Option module in slot 1: watchdog timeout. The
module has started the watchdog system, but has not subsequently serviced the
watchdog within the timeout period.

Option module in slot 1: error. The module has
detected an error and tripped the drive. The reason for the error is stored
in parameter x.50.
|
|
203
|
SL1.nF
|
Option module in slot 1: not fitted. The option
module is identified by the drive by an option code. The drive stores the
codes of the modules fitted when the drive parameters are saved. The stored
codes are compared with the codes from the option modules at power-up. If a
module is not present, but a code is stored in drive EEPROM to indicate that
it should be fitted the drive trips.
|
|
204
|
SL1.dF
|
Option module in slot 1: different fitted. The
option module is identified by the drive by an option code. The drive stores
the codes of the modules fitted when the drive parameters are saved. The
stored codes are compared with the codes from the option modules at power-up.
If a module is different to the code stored in drive EEPROM the drive trips.
