<1> One terminal can be used for several drives to form a group.
<2> Switch-on delay according to [1024], starts when the "request pulse cancelation CU" is withdrawn.
<3> Value range: p9620 = 0 or r0722.0...7 (for CU310 and CX32 only r0722.0...3).
<4> Redundant functions in the Control Unit (CU) and Motor Modules (MM).
<5> Transistors inhibited for a "0" signal.
<6> Only for Booksize.
<7> Only for VECTOR. The number of active AND inputs corresponds to the number of Motor Modules
connected in parallel (p0120).
