A791 Brake resistor
Cause
The current/voltage
hardware setting of an
analog input does not
correspond to parameter
settings.
User load curve
configuration error.
Speed points inconsistent.
Frequency points
inconsistent.
Underload point above
overload point.
Overload point below
underload point.
Motor current is too high.
All three output phases are
disconnected from motor.
Motor is operating in stall
region because of e.g.
excessive load or insufficient
motor power.
Brake resistor broken or not
connected.
What to do
Check the event log for an auxiliary
code. The code identifies the analog
input whose settings are in conflict.

Note: Control board reboot (either by
cycling the power or through

Check if parameter
use of a motor disconnect switch. If
not, check the following:
• All switches between drive and
motor are closed.
• All cables between drive and motor
are connected and secured.
If no issue was detected and drive
output was actually connected to
motor, contact ABB.
Check motor load and drive ratings.
Check fault function parameters.
Check that a brake resistor has been
connected.
Check the condition of the brake
resistor.
