C.3 Home Mode1
In Home Mode1, the motor will start up at speed FL, and accelerate to
speed FH towards the home sensor. Once the home sensor is reached, the
motor will decelerate. The main difference with mode0 is that in this
mode, the motor will go back and approach the home again with low
speed FL. This makes the stop point even closer to the raising edge of the
home sensor.
If the home sensor was active at start up, or the limit switch was met first,
the motor will go in the opposite direction when reaching the limit switch.
Then it will keep moving until it crosses the home sensor, and finally
search the home signal again.
