6.6.1 D.I Setting 1
You can assign three operation functions (RUN/STOP, STEP, HOLD) which is related to basic
operation function in the D.I Setting 1[Fig. 109]. User can set up HIGH/LOW operation to these
three operation functions. As LEVEL input, RUN/STOP and HOLD input should maintain their
level continuously. Because STEP operation is EDGE input, it operates one time according to its
setting in case of H->L or L->H. You should enter H and L continuously in order to keep on
STEP operation.
•Overlapping assignment of D.I number is not available in the inputs of RUN/STOP,
STEP, HOLD operation function. Also when input of STEP and HOLD come is at the
same time, it ignores STEP input and it handles HOLD input only.
•Regardless of control action(Running or Stop), external D.I is always displayed and
handled internally according to its input status.
