INC1, INC10, INC100, INC1000, INC10000, INCvar, continuous
DBX53.0-6
Edge evaluation: No
Signal state 1 The corresponding machine function is active.
● Bit 0 = 1 INC
● Bit 1 = 10 INC
● Bit 2 = 100 INC
● Bit 3 = 1000 INC
● Bit 4 = 10000 INC
● Bit 5 = Var. INC
● Bit 6 = continuous
The reaction to actuation of the traversing key or rotation of the handwheel varies, depending on
which machine function is active.
Signal state 0 The machine function in question is not active.
