Cause
Interface board (between power
unit and control unit)
temperature has exceeded
internal alarm limit.
Input bridge or braking chopper
temperature has exceeded
internal alarm limit.
Drive temperature based on
thermal model has exceeded
internal alarm limit.
Cyclical communication
between drive and fieldbus
adapter module or between
50.02
PLC and fieldbus adapter
module is lost.
Control panel or PC tool
selected as active control
location for drive has ceased
46.03
communicating.
Analogue input AI1 or AI2 signal
has reached limit defined by
parameter 13.13 AI SUPERVIS
13.12
ACT.
The drive does not have a
functionality requested by PLC,
or requested functionality has
not been activated.
Parameters in group 99 have
not been set.
What to do
Let drive cool down.
Check for excessive ambient temperature.
Check for cooling fan failure.
Check for obstructions in the air flow.
Check the dimensioning and cooling of the
cabinet.
Let drive cool down.
Check for excessive ambient temperature.
Check for cooling fan failure.
Check for obstructions in the air flow.
Check the dimensioning and cooling of the
cabinet.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against unit power.
Check status of fieldbus communication. See
appropriate User's Manual of fieldbus adapter
module.
Check fieldbus parameter settings. See
parameter group 50 on page 172.
Check cable connections.
Check if communication master can
communicate.
Check PC tool or control panel connection.
Check control panel connector.
Replace control panel in mounting platform.
Check analogue input AI1/2 source and
connections.
Check analogue input AI1/2 minimum and
maximum limit settings, parameters
and 13.03 / 13.07 and 13.08.
Check PLC programming.
Check fieldbus parameter settings. See
parameter group 50 on page 172.
Check that all the required parameters in
group 99 have been set.
Note: It is normal for this alarm to appear
during the start-up until the motor data is
entered.
