Alarms and Warnings
WARNING
If a protection trips or the drive enters the emergency mode, the drive is locked and the
motor starts idling!
2.7.1.
What Happens When a Protection Trips
NOTE
Before operating the drive in emergency conditions, carefully read this section and the following section,
What To Do When an Alarm Trips.
The drive alarms are detailed below.
When a protection / alarm trips:
1) the
ALARM
LED on the keypad comes on;
2) the page displayed on the keypad is the root page of the
FAULT LIST
;
3) the
FAULT LIST
is refreshed;
In factory-setting, when the drive is switched on after an alarm has tripped
—which has not been reset—it is
kept in emergency condition.
If the drive is in emergency mode when switched on, this could be due to an alarm tripped before the
drive was reset
.
To avoid storing the alarms tripped before the drive is switched off, set parameter
C257
section 2.6.7.
The drive stores the moment when an alarm trips to the
FAULT LIST
(supply
–time and operation–time). The
drive status when the alarm tripped and some measures sampled when the alarm tripped are also stored to
the Fault List.
The readout and storage of the fault list can be very useful to detect the cause responsible for the alarm and
its possible solution (see also section 2.5.6).
NOTE
Alarms A001 to A039 relate to the main microcontroller (DSP Motorola) of the control board,
which detected a fault on the control board itself. No fault list is available for Alarms A001 to A039
and no Reset command can be sent via serial link; alarms can be reset through the RESET
terminal on the terminal board or the RESET key on the keypad. No software for the keypad
interface is available; the drive parameters and measures cannot be accessed via serial link.
Avoid resetting alarms A033 and A039, as they trip when the flash memory is not provided with its
correct software. Alarms A033 and A039 can be reset only when proper software is downloaded
for the inverter flash memory.
