12 Diagnostics, alarms, troubleshooting
The drive is provided with a diagnostics program that allows the user an easier
troubleshooting. The alarms immediately lock the drive. The error code is displayed on the
keypad intermittently and corresponds to parameter Pr23. In Pr24, the last detected alarm is
stored, except for that relating to under-voltage (2) which could occur upon every switching
off. In this way, if the drive is automatically disconnected from the mains after an alarm,
through Pr24 it is possible to assess the alarm that has caused the lock.
Alarms are of the non-returning type (except for UV, under-voltage, which has a
programmable return): if an alarm has tripped, it remains stored also when the problems
determining it has been solved. To deactivate the alarms, remove the problem first, by
identifying the type of fault with the aid of the following table and carrying out the
recommended actions, and then reset through the Pb99.10. Alarms can also be reset by
disconnecting the logics or turning off and on again the drive.
12.1
Summary of alarm and diagnostics use bit
parameters:
Par. Description
Pb99.10
Command to reset alarms.
This command sets Pr23 and Pr24 to 0. The bit is set to
1 on the keypad, “reset” is displayed and then returns to zero, if the alarm persists, it
remains on the display. This command cannot be used if there is a check-sum error
(Pr23 = 10, 11). In this case, it is necessary to set the default parameters (b99.12)
and then reset the alarm.
Danger
: Recovering default parameters deletes the previous parameter calibrations.
Pb99.8
UV auto reset.
Default=0. If set to 1, the under-voltage alarm will automatically be
set to 0 when power returns.
Pb41.7
External alarm
. An alarm that can be used by the user.
Pb41.8
Auxiliary alarm
. A second alarm that can be used by the user.
These two alarms can be reached through the PLC. The drive lock can be performed
by loading a logical input or an event associated to a bit parameter of one of these
alarms. All of these alarms can only be reset through Pb99.10.
Pb41.4
Converter O.K.
, otherwise =0 . It can be used by the PLC to activate a logical
fault reporting output.
