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 type and location settings
of the modules (parameters 14.1, 14.2,
15.1, 15.2, 16.1 and 16.2).
The I/O extension module types and
locations specified by parameters do
not match the detected configuration.

Check that the modules are properly
installed.
Check the auxiliary code. See Drive
application programming manual (IEC
61131-3) (3AUA0000127808 [English]).
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: 92 Encoder

configuration). “ZZZZ” indicates the
problem (see actions for each code
below).
Check motor gear settings (90.43
and 90.44).
Motor gear definition invalid or
outside limits.

changes in the settings.
Check encoder status.Encoder stopped working.0003
Check for slippage between encoder
and motor.
