Code Error Text
218 CLOCK PAL
NOT OK
The main uC sends an analog
signal towards trhe slave uC to
reset the slave uC on demand.
When the slave uC detects the
analog signal external to a win-
dow from 2.2 to 2.8 and not in
the range to generate the reset
on demand, the slave uC
raises this alarm.
It is necessary to replace the controller.
99 INPUT ERROR
#1
It occurs when the voltage on
CNA#4 (NK1: Lower Potential
Terminal of the Safety Con-
tacts) is higher than 12 V
before to turn the safety con-
tacts closed.
When the safety contacts are open, the volt-
age on CNA#4 is expected to be close to 0
Vdc and this is independent from whether
the safety contacts are connected to a plus
battery or to a minus battery. In the first
case (safety contacts connected to a plus
battery), when the safety contacts are
open, CNA#4 is connected to a minus bat-
tery through a load. Only a harness mistake
may connect NK1 to a higher than 12 volt-
age.
212 MICRO SLAVE
#8
It occurs when the encoder count-
ing of the main uC is not
matched with the encoder
counting the slave uC.
It is necessary to replace the controller.
219 STEPPER
MOTOR MISM
This alarm occurs if the frequency
and the amplitude of the volt-
ages from the stepper motor
lines are mismatched in
between. In normal condition
when the amplitude of the
stepper motor lines increases,
the frequency of the stepper
motor lines must increase too.
It is necessary to replace the controller.
220 MOTOR
LOCKED
This alarm occurs if the current in
the steering motor stays close
to the maximum current longer
tan 1 sec.
Search for a mechanical problem locking the
motor. To help in the fault finding, set
DEBUG OUTPUT to level 11.
