Cause
A reference source is
simultaneously connected to
multiple parameters with
different units.
The current/voltage hardware
setting of an analog input does
not correspond to parameter
settings.
User load curve configuration
error.
0000 Speed points inconsistent.
0001 Frequency points inconsistent.
0002 Underload point above
overload point.
0003 Overload point below
underload point.
Motor is operating in stall
region because of e.g.
excessive load or insufficient
motor power.
No feedback received from
external fan.
What to do
Check the reference source selection
parameters.
Check the auxiliary code (format
XXYY 00ZZ). "XX" and "YY" specify the
two 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, 44.09],
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.
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
96.08 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.
Check that each frequency point
(37.16...37.20) has a higher value than
the previous point.
Check that each overload point
(37.31...37.35) has a higher value than
the corresponding underload point
(37.21...37.25).
Check motor load and drive ratings.
Check fault function parameters.
Check external fan (or other equipment
controlled) by the logic.
Check settings of parameters
35.100...35.106.
