0 = OFF1 (braking with ramp-function generator, then pulse cancellation & ready for switching on)
= ON (pulses can be enabled)
1 = No OFF2 (enable is possible)
0 = OFF2 (immediate pulse suppression and switching on inhibited)
1 = No OFF3 (enable is possible)
0 = OFF3 (braking with the OFF3 ramp p1135, then pulse suppression and switching on inhibited)
1 = Enable operation (pulses can be enabled)
0 = Inhibit operation (cancel pulses)
1 = Operating condition (the ramp-function generator can be enabled)
0 = Inhibit ramp-function generator (set the ramp-function generator output to zero)
1 = Enable the ramp-function generator
0 = Stop the ramp-function generator (freeze the ramp-function generator output)
1 = Enable setpoint
0 = Inhibit setpoint (set the ramp-function generator input to zero)
= Acknowledge faults
