Signal2 Amplitude Out of Range:
The adapted amplitude is too high or
too low.
Signal1 Offset Out of Range:
The adapted offset is too high or too
low.
Signal2 Offset Out of Range:
The adapted offset is too high or too
low.
SIN COS Sensor Not Connected:
Check that the unit circle vector is
constant. The system will detect a
broken signal even if the motor is not
rotating.
Speed Error:
The speed calculated from the
sensor signals is not valid.
Negative Positive Limit:
The calculation of the positive start of
the slow down position resulted in a
negative value which is not allowed.
Positive Negative Limit:
The calculation of the negative start
of the slow down position resulted in
a positive value which is not allowed.
Dynamic Reference Ration Error:
The monitoring of the dynamic
reference ration has detected an
error. This indicates that a dynamic
reference ratio value below the
dynamic reference ratio minimum
limit has been detected when not
allowed.
Stepper Signal1 High:
The filtered stepper signal1 is above
4000mV.
Stepper Signal1 Low:
The filtered stepper signal1 is below
1000mV.
