12.7 Status idincations
Table 12-8 Status indications
Table 12-9 Option module and NV Media Card and other status
indications at power-up
12.8 Programming error indications
The following are the error messages displayed on the drive keypad
when an error occurs during programming of drive firmware.
Table 12-10 Programming error indications
12.9 Displaying the trip history
The drive retains a log of the last ten trips that have occurred. Trip 0
(10.020) to Trip 9 (10.029) store the most recent 10 trips that have
occurred where Trip 0 (10.020) is the most recent and Trip 9 (10.029) is
the oldest. When a new trip occurs it is written to Trip 0 (10.020) and all
the other trips move down the log, with oldest being lost. The date and
time when each trip occurs are also stored in the date and time log,
i.e. Trip 0 Date (10.041) to Trip 9 Time (10.060). The date and time are
taken from Date (06.016) and Time (06.017). The date / time source can
be selected with Date / Time Selector (06.019). Some trips have sub-trip
numbers which give more detail about the reason for the trip. If a trip has
a sub-trip number its value is stored in the sub-trip log, i.e. Trip 0 Sub-trip
Number (10.070) to Trip 9 Sub-trip Number (10.079). If the trip does not
have a sub-trip number then zero is stored in the sub-trip log.
If any parameter between Pr 10.020 and Pr 10.029 inclusive is read by
serial communication, then the trip number in Table 12-3 is the value
transmitted.
The trip logs can be reset by writing a value of 255 in Pr 10.038.
12.10 Behavior of the drive when tripped
If the drive trips, the output of the drive is disabled so the load coasts to a
stop. If any trip occurs the following read only parameters are frozen until
the trip is cleared. This is to help in diagnose the cause of the trip.
If the parameters are not required to be frozen then this can be disabled
by setting bit 4 of Pr 10.037.

Writing To NV Card
Data being written to NV Media
Card
Data is being written to a NV Media Card to ensure that its copy of the
drive parameters is correct because the drive is in Auto or Boot mode
Waiting For Power System Waiting for power stage
The drive is waiting for the processor in the power stage to respond
after power-up
Waiting For Options Waiting for an option module
The drive is waiting for the Options Modules to respond after power-up
Uploading
From
Options Loading parameter database
At power-up it may be necessary to update the parameter database
held by the drive because an option module has changed or because
an applications module has requested changes to the parameter
structure. This may involve data transfer between the drive an option
modules. During this period ‘Uploading From Options’ is displayed
Error
String
Reason Solution
Error 1
There is not enough drive
memory requested by all
the option modules.
Power down drive and remove
some of the option modules
until the message disappears.
Error 2
At least one option module
did not acknowledge the
reset request.
Power cycle drive
Error 3
The boot loader failed to
erase the processor flash
Power cycle drive and try
again. If problem persists,
return drive
Error 4
The boot loader failed to
program the processor
flash
Power cycle drive and try
again. If problem persists,
return drive
Error 5
One option module did not
initialize correctly. Option
module did not set Ready
to Run flag.
Remove faulty option module.
