AI parametrization
The current/voltage
jumper setting of an
analog input does not
correspond to parameter
settings.
Check the auxiliary code. The code
identifies the analog input whose
settings are in conflict.
Adjust either the jumper setting (on the
drive control unit) or parameter
Note:
Control board reboot (either by
cycling the power or through
parameter
) is
required to validate any changes in the
jumper settings.
A780
Motor stall
Programmable warning:
Motor is operating in stall
region because of e.g.
excessive load or
insufficient motor power.
Check motor load and drive ratings.
Check fault function parameters.
A781
Motor fan
Programmable warning:
No feedback received
from external fan.
Check external fan (or other equipment
controlled) by the logic.
Check settings of parameters
…
A782
FEN temperature
Error in temperature
measurement when
temperature sensor (KTY
or PTC) connected to
encoder interface FEN-
xx is used.
setting
corresponds to actual encoder
interface installation.
Error in temperature
measurement when KTY
sensor connected to
encoder interface FEN-
01 is used.
FEN-01 does not support temperature
measurement with KTY sensor. Use
PTC sensor or other encoder interface
module.
A791
Brake resistor
Brake resistor broken or
not connected.
Check that a brake resistor has been
connected.
Check the condition of the brake
resistor.
A793
BR excess temperature
Brake resistor
temperature has
exceeded warning limit
defined by parameter
.
Stop drive. Let resistor cool down.
Check resistor overload protection
function settings (parameter group
Check warning limit setting, parameter
.
Check that braking cycle meets
allowed limits.
A794
BR data
Brake resistor data has
not been given.
Check the resistor data settings
(parameters
). The
parameter is specified by the auxiliary
code.
0000 0001 Resistance value too
low.
Check value of
