3. Instruction Set
3-375
10. M1305 and M1306 can change the output direction of CH0/CH1 set in D
2
. When S is “-“, D
2
will
be ON, however, if M1305/M1306 is set ON before instruction executes, D
2
will be OFF during
execution of instruction..
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. DRVA/DDRVA instructions do NOT support Alignment Mark and Mask function.
Program Example:
When M10 = ON, DRVA instruction executes absolute positioning on Y0 at target position 20000,
target frequency 2kHz. Y5 = OFF indicates positive direction.

Points to note:
1. Operation of absolute positioning:
Pulse output executes according to the specified absolute position from zero point
