MLXSPI-01
MLXSPI Programming kit
10. MLX90804 definition interface
This interface contains all parameters as are
described in application note MLX90804AN3
‘manual for definition of the options’. Use this
document as a guide to define all values.
Note that all speed settings are in RPM. The unit
for the minimum and maximum firing angle is
0.01*msec. This means that a value of 800
corresponds to 8 msec.
The parameter MAP is calculated and updated
automatically by the program.
During the consistency check a lot of verifications
are done. A few examples are:
1. Are the low speed limitation, the number of
poles and the SPD multiplier coefficient
consistent with the requirement as described in
MLX90804AN3?
2. Is the maximum speed limitation higher then
the speed settings on all potentiometer
settings?
During the transformation of the parameters to
programming values rounding errors can be
introduced. As an example, the maximum speed
limitation can only be programmed with a
resolution of 5 bits.
The box, indicating ‘chip version’, is used to
distinguish possible future versions of the kitpart.
The value can currently not be changed.
