Warning / Aux. code
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 is operating in
stall region because of
e.g. excessive load or
insufficient motor
power.
Brake resistor short
circuit or brake chopper
control fault. For drive
frames R6 or larger.
Brake resistor
temperature has
exceeded warning limit
defined by parameter
43.12 Brake resistor
warning limit.
Brake resistor data has
not been given.
Resistance value too
low.
Thermal time constant
not given.
Cause What to do
Check the event log for an 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
(37.20...37.16) 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 brake chopper and brake
resistor connection.
Ensure brake resistor is not damaged.
Stop drive. Let resistor cool down.
Check resistor overload protection
function settings (parameter group
43 Brake chopper).
Check warning limit setting,
parameter 43.12 Brake resistor
warning limit.
Check that the resistor has been
dimensioned correctly.
Check that braking cycle meets
allowed limits.
One or more of the resistor data
settings (parameters 43.08...43.10) is
incorrect. The parameter is specified
by the auxiliary code.
Check value of 43.10.
Check value of 43.08.
