2041 MOTOR NOM VALUE
(0x6383)
The motor configuration
parameters are set incorrectly.
Check the settings of the motor configuration
parameters in group 99.
The drive is not dimensioned
correctly.
Check that the drive is sized correctly for the
motor.
2042 D2D CONFIG
(0x7583)
The settings of drive-to-drive
link configuration parameters
(group 57) are incompatible.
Check the settings of the parameters in group
57.
2043 STALL
(0x7121)
Programmable fault:
46.09 STALL FUNCTION
Motor is operating in stall region
because of, eg, excessive load
or insufficient motor power.
Check motor load and drive ratings.
Check fault function parameters.
2047 SPEED FEEDBACK
(0x8480)
No speed feedback is received. Check the settings of the parameters in group
22.
Check encoder installation. See the
description of fault 0039 (ENCODER1) for
more information.
Check encoder cabling. See the descriptions
of alarms 2031 (ENCODER 1 CABLE) and
2032 (ENCODER 2 CABLE) for more
information.
2048 OPTION COMM LOSS
(0x7000)
Communication between drive
and option module (FEN-xx
and/or FIO-xx) is lost.
Check that option modules are properly
connected to Slot 1 and (or) Slot 2.
Check that option modules or Slot 1/2
connectors are not damaged. To determine
whether module or connector is damaged:
Test each module individually in Slot 1 and
Slot 2.
2072 DC NOT CHARGED
(0x3250)
The voltage of the intermediate
DC circuit has not yet risen to
operating level.
Wait for the DC voltage to rise.
2073 SPEED CTRL TUNE FAIL
(0x8481)
Speed controller autotune
routine did not finish
successfully.
See parameter 28.16 PI TUNE MODE.
2075 LOW VOLT MODE
CONFIG
(0xC015)
Low voltage mode has been
activated but the parameter
settings are outside allowable
limits.
Check the Low voltage mode parameters in
group 47. See also section Low voltage mode
on page 48.
2079 ENC 1 PULSE
FREQUENCY
(0x738B)
Encoder 1 is receiving too high
data flow (pulse frequency).
Check encoder settings.
Change parameters 93.03 ENC1 SP
CALCMODE and 93.13 ENC2 SP
CALCMODE to use only one channel pulses/
edges.
