(c) Magnetic sensor
An accurate gear ratio (pulley ratio) is required from
the motor shaft to the detector rotary axis. Make sure
that the correct number of gear teeth is set in SP025
(GRA1) to SP032 (GRB1).
SP025 to SP028=A × C × E
SP029 to SP032=B × D × F
The SP123 (MGD0) to SP125 (MGD2) parameters
are set as shown below according to the magnetic
sensor type.
