With two limit switches and one reference point switch; reference point approach with
approaching the reference mark of the encoder.
ï Terminal X2A.14 = Limit switch right (di.19 = 32)
ï Terminal X2A.15 = Limit switch left (di.20 = 64)
ï Terminal X2A.11 = Reference point switch (di.12 = 67108864)
ï Terminal X2A.10 = Start Reference point approach (di.11 = 134217728)
ï Reference speed = -100 rpm with counter-clockwise rotation (PS.21=-100)
If the zero impulse is not be approached (PS.14 Bit 2 = off), only the reference point
switch is cleared and the drive is then stopped.
