Delta DVP-EX2

3. Instruction Set
3-481
that the pulses are output in the positive direction. When D1312 is a negative value (the minimum
value is -30000), it indicates that the pulses are output in the negative direction. For example, if
D1312 is k-100, it means that DOG stops immediately after DOG leaves DOG switch and another
100 pulses will be output in the negative direction with JOG frequency. Please refer to state 6 for
the timing diagram of this function.
12. This instruction should not be used in the interrupt programs or subroutine that only be called once
or used with auto-reset flags.
