With two limit switches and one reference point switch; reference point run with approach
of the reference marking of the encoder.
• Terminal X2.3 = limit switch right (di.11 = 16)
• Terminal X2.4 = limit switch left (di.12 = 17)
• Terminal X2.5 = reference point switch (di.3 = 12)
• Reference speed -100 min
• Starting of reference point approach with X1.7 (di.5 = 10) or by bus / PC with
parameter Pd.1 = 2 (Pc.10 = 0)
If the zero pulse shall not be approached (Pc.10 = 2), then only the reference point switch
is cleared and the drive stops then.
