2.5 Analogue to position mode
Example:
A voltage source feeds the MAC140 motor that has 4096 counts per revolution (stand-
ard).
The desired working range is 5000 counts (approx. one revolution) and it is desired to
have an offset from the zero point where the Homing was done of 1000 counts (1/4 mo-
tor revolution).
Therefore the "Offset" register is set to 1000 counts and the "Full range" register is set
to 5000 counts. Please notice that a bit rounding is done since the analogue input and also
the motor encoder has a limited resolution.
In addition its desired to have a certain filtering at the input meaning that the motor
should not move unless the input voltage changes more than what correspond to a
movement of 50 counts.
As a result the "Hysteresis" register is set to 50 counts.
Ensure the "Profile data" containing motor "Velocity", "Acceleration" etc. is set to prop-
er values in order not to limit motor operation unintentionally.
