23:15 MOTOR NOT FOLLOW
This error code is generated by the MCU. The MCU continuously estimates the motor speed. If the estimated speed
is less than 180 rpm 10 seconds after drive command, or higher than 180 rpm 60 seconds after stop command, the
error will be shown.
Possible causes:
• Break in one of the phases to the motor (cables or connectors). This error can be suspected if the motor does not
rotate for 10 seconds (the motor will not start with only two phases).
• Check that the drum can be rotated easily.
• Check motor windings for open circuit using a Motor tester.
Further information can be obtained by studying the contents of
MCU ERROR LOG 1
and
MCU ERROR LOG 2
. Study the
following:
•
MOTOR NOT FOLLOW
(specifies how many times this error code has occurred).
•
LAST ERROR CODE N/8
(shows the 8 latest error codes).
Recommended action:
1. Replace the defective part.
23:255 UNDEFINED ERROR
This error code is generated by the MCU. The MCU reports an error that is not defined.
FAN MOTOR COMMON
30:1 O.H. FAN MOTOR
This error code will be shown if the control system detects that the input OH FAN MOTOR is deactivated during pro-
gram run.
The overheating protection is automatically restored. When the overheating protection is restored the error code is
automatically reset and the ongoing program will continue. A long press on the control knob/start button will make
the control system reset and the ongoing program will be ended.
The error code can be trigged if:
• The motor is very warm. Check that the vent holes in the motor are not covered.
If the overheating protection is not trigged, but there is still an error code:
• Check the harness, connectors and functions by reading the electrical schematic and by using the
SHOW INPUTS
menu when the machine is in service mode.
