3. Instruction Set

3-371

11. Ramp-down time of CH0 and CH1 can be particularly modified by using (M1534, D1348) and

(M1535, D1349). When M1534 / M1535 = ON, CH0 / CH1 ramp-down time is specified by

D1348 / D1349.

12. If M1078 / M1104 = ON during instruction execution, Y0 / Y2 will pause immediately and

M1538 / M1540 = ON indicates the pause status. When M1078 / M1104 = OFF, M1538 /

M1540 = OFF, Y0 / Y2 will proceed to finish the remaining pulses.

13. DRVI instruction supports Alignment Mark and Mask function. Please refer to the explanation

in API 59 PLSR instruction.

Program Example:

When M10= ON, 20,000 pulses (relative position) at 2kHz frequency will be generated from Y0. Y1=

OFF indicates positive direction.

Points to note:

1. Operation of relative positioning:

Pulse output executes according to the relative distance and direction from the current position
