Warning Cause What to do
A2B1 Overcurrent Output current has
exceeded internal
alarm limit.
Check motor load.
Check acceleration times in
parameter
group 23 Speed reference
ramp (rpm
operation mode) or 28
Frequency reference chain (Hz
operation
mode).
Also check parameters 46.01 Speed
scaling and 46.02 Frequency scaling.
Check motor and motor cable
(including
phasing and delta/star
connection).
Check there are no contactors
opening
and closing in motor cable.
Check that the data in parameter
group
99 Motor data corresponds to
the motor
rating plate.
Check that there are no power factor
correction capacitors or surge
absorbers
in motor cable.
A2B4 Short circuit Short-circuit in motor
cable(s) or motor.
Check motor and motor cable for
cabling
errors.
Check that there are no power factor
correction capacitors or surge
absorbers in motor cable.
A3D0 Grid
ridethrough
Grid voltage is below
the
internal threshold
so the drive is
operating in low
voltage ridethrough
mode.
Check the transformer secondary
voltage.
A5F4 Control unit
battery
The battery of the
control unit is low.
Replace control unit battery. Refer to
the
HW manual for instructions on
battery
replacement.
This warning can be suppressed
using
parameter 31.40.
A7EE Panel loss Control panel or PC
tool
selected as
active control
location for drive has
ceased
communicating.
Check PC tool or control panel
connection.
Check control panel connector.
Disconnect and reconnect the control
panel.
