sets of parameters where the source
was connected to (01 = speed
reference chain [22.11, 22.12, 22.15,
22.17], 02 = frequency reference chain
[28.11, 28.12], 03 = torque reference
chain [26.11, 26.12, 26.16], 04 = other
torque-related parameters [26.25,
30.21, 30.22, 44.9], 05 = process PID
control parameters [40.16, 40.17,
40.50, 41.16, 41.17, 41.50]). “ZZ”
indicates the conflicting reference
source (01…0E = index in parameter
group 3, 33 = process PID control, 3D
= motor potentiometer, 65 = AI1, 66 =
AI2, 6F = frequency input).
Check the auxiliary code. The code
identifies the analog input whose
settings are in conflict.
The current/voltage hardware setting
of an analog input does not
correspond to parameter settings.

Adjust either the hardware setting (on
the drive control unit) or parameter
12.15/12.25.
Note: Control board reboot (either by
cycling the power or through
parameter 96.8 Control board boot)
is required to validate any changes in
the hardware settings.
Check the auxiliary code (format XXXX
ZZZZ). “ZZZZ” indicates the problem
(see actions for each code below).

Check that each speed point
(parameters 37.11…37.15) has a
higher value than the previous point.
Speed points inconsistent.0000
Check that each frequency point
(37.16…37.20) has a higher value
than the previous point.
Frequency points inconsistent.0001
Check that each overload point
(37.31…37.35) has a higher value
Underload point above overload
point.
0002
than the corresponding underload
point (37.21…37.25).
Check that each overload point
(37.31…37.35) has a higher value
Overload point below underload
point.
0003
than the corresponding underload
point (37.21…37.25).
Check motor load and drive ratings.Motor is operating in stall region
because of e.g. excessive load or
insufficient motor power.

Check fault function parameters.
Check external fan (or other
equipment controlled) by the logic.
No feedback received from external
fan.
