A10 = Emergency-stop relay
AF = drive enable of the drive controllers
Bb1 = power supply unit ready (drive system)
Bb = drive controllers ready
CNC = lag error message of control (use only contacts that do not open when E-stop switch is open)
K1 = mains contactor in power supply unit
K4 = drive enable signal control
RF = drive enable signal of the control unit
S1 = Emergency-stop
S2 = axis end position
S4 = power OFF
S5 = power ON
