Check if parameter 95.26 enables
the use of a motor disconnect
switch. If not, check the following:
All three output phases
are disconnected from
motor.
Motor discon-
nect

•
All switches between drive and
motor are closed.
•
All cables between drive and
motor are connected and se-
cured.
If no issue was detected and drive
output was actually connected to
motor, contact ABB.
Check brake resistor.
Brake resistor fault.

Check brake chopper and brake
resistor connections.
Brake resistor short cir-
cuit or fault in brake
chopper.

Stop the drive. Let resistor cool
down. Check resistor overload pro-
tection function settings, warning
limits, resistor dimensioning and
braking cycle limits.
Brake resistor temperat-
ure exceeded warning
limit.
BR excess tem-
perature
A793
3 - maximum continuous power not
given
1 - Resistance value too low
2 - Thermal time constant not given
Check resistor data settings.
No brake resistor data.

Let chopper cool down. Check am-
bient temperature, cooling fan, air
flow, cabinet cooling, resistor
overload protection function set-
tings, chopper resistor value, brak-
ing cycle and supply voltage.
Brake chopper IGBT tem-
perature exceeded intern-
al warning limit.
BC IGBT excess

Make sure that the I/O built in/ex-
tension module is connected to the
device.
The I/O built in/extension
module is not connected
to the device properly.
