0001 Load gear definition invalid or
outside limits.
0002 Feed constant definition invalid
or outside limits.
0003 Motor/load gear definition
invalid or outside limits.
0004 Encoder not configured.
0005 Encoder stopped working.
Emergency stop did not finish
within expected time.
Ramp stop did not finish within
expected time.
Maximum allowed output
frequency exceeded.
What to do
Check the auxiliary code (format XXYY
ZZZZ). "XX" specifies the number of the
encoder interface module (01:
91.11/91.12, 02: 91.13/91.14), "YY"
specifies the encoder (01:
configuration, 02: 93 Encoder 2
configuration). "ZZZZ" indicates the
problem (see actions for each code
below).
Check load gear settings
90.54).
Check feed constant settings
90.64).
Check motor/load gear settings
and 90.62).
Check encoder settings
configuration or 93 Encoder 2
configuration).
Use parameter 91.10 Encoder parameter
refresh) to validate any changes in the
settings.
Check encoder status.
Check the settings of parameters
Emergency ramp supervision
Emergency ramp supervision
Check the predefined ramp times
(23.11...23.19 for mode Off1,
mode Off3).
Check the settings of parameters
Ramp stop supervision
stop supervision delay.
Check the predefined ramp times in
parameter group 23 Speed reference
ramp.
