3. The motor is on the right of the home switch at the beginning of the homing. After having found
the mechanical end stop, it comes back. When it finds the home switch (in the wrong direction),
it keeps moving the distance given by parameter K48 before changing direction a second time
to find the home switch in the right direction. Parameter K48 must be bigger than the home
switch length.
Remark: When a DSCDM is used with K40 = 2 and 3, the HOME NOT POSSIBLE error (M64=69) will
appear if bits# 2 and 3 of parameter K58 are equal to 0.
K40 = 3:
Same as K40 = 2 but with a negative movement.
K40 = 4:
Homing on a limit switch with a positive movement. After having found the limit switch, the motor moves back
the distance given by K47.
If at the beginning of the homing the motor is on the positive limit switch, the motor moves back the distance
given by K48.
