Backgauge Home Position Sensor
Fig 10-
When the backgauge moves
backward, B21 detects the sensor
plate and turns on. When B21 turns on,
M20 rotates in the reverse direction
and the backgauge moves forward,
and B21 turns off. The motor stops at
the position where Z-phase from the
encoder is detected for the first time in
one rotation of M20.
This position is the home position.
