Alarm indications

In any mode an alarm flashes alternately with the data displayed on the
2nd row when one of the following conditions occur. If action is not taken
to eliminate any alarm except "Autotune", and "PLC" the drive may
eventually trip. Alarms flash once every 640 ms except "PLC" which
flashes once every 10s. Alarms are not displayed when a parameter is
being edited.

Table 13-4 Alarm indications

Lower
display
Hot Heatsink alarm is active
The temperature displayed in Pr 7.04 has exceeded the alarm level
(see Pr 7.04).
OVLd Motor overload
2
The motor I t accumulator (Pr 4.19) in the drive has reached 75% of
the value at which the drive will be tripped and the load on the drive is >
motor rated current (Pr 5.07 (SE07, 0.28)).
Autotune Autotune in progress
The autotune procedure has been initialised. 'Auto' and 'tunE' will flash
alternatively on the display.
CLt Current limit is active
Indicates that current limits are active.
PLC Onboard PLC program is running
An Onboard PLC program is installed and running. The lower display
will flash 'PLC' once every 10s.
S.OV Indicated suppressor over voltage
Indicates that the over voltage suppressor voltage is within 30V of the
trip level
S.rS Suppressor resistor overload
Indicates that the external voltage suppressor resistor is in an overload
condition
ESt SPd Estimated speed selected
The drive has lost speed feedback and automatically selected
Estimated speed mode. See Pr 3.55 (Select estimated speed on
feedback loss).

Displaying the trip history

The drive retains the last 10 trips that have occurred.
Table 13-6 shows parameters used to store the last 10 trip.

Behavior of the drive when tripped

If the drive trips the output of the drive is disabled so that the drive stops
controlling the motor. If any trip occurs (except UV) the following read
only parameters are frozen to help in diagnosing the cause of the trip

Analog and digital I/O
The analog and digital I/O on the drive continue to work correctly if a trip
occurs, except the digital outputs will go low if one of the following trips
occur: O.Ld1, PS.24V.
Drive logic functions
The drive logic functions (i.e. PID, variable selectors, threshold
detectors, etc.) continue to operate when the drive is tripped.
Onboard PLC program
The Onboard PLC program continues to run if the drive is tripped, except
if one of Onboard PLC program trips occur.
