- The current position (32-bit data) of CH0 (Y0, Y1) which is stored in D1031(high), D1030
(low)
- The current position (32-bit data) of CH1 (Y2, Y3) which is stored in D1337(high), D1336
(low).
In the reverse direction of the pulse output, the value in (D1031, D1330) and (D1336, D1337)
decreases.
7. D1343 (D1353) is the ramp up/down time setting of CH0
(
CH1
)
. Available range: 20 ~
32,767ms. Default: 100ms. The ELC will use the upper/lower value as the set value when the
value exceeds the allowable range.
8. D1340 (D1352) is the start/end frequency setting of CH0
(
CH1
)
. Available range: 6 to
100,000Hz. The ELC will use the upper/lower value as the set value when the value exceeds
the allowable range.
9. M1305 and M1306 can change the output direction of CH0
/
CH1 set in D
2
. When S is “-“, D
2
will
be ON. If M1305/M1306 is set ON before the instruction executes, D
2
will be OFF during
execution of the instruction.
10. The ramp-down time of CH0 and CH1 can be modified by using (M1534, D1348) and (M1535,
D1349). When M1534 / M1535 = ON, CH0 / CH1 ramp-down time is specified by D1348 /
D1349.
11. 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.
12. DRVA/DDRVA instructions do NOT support Alignment Mark and Mask function.
Program Example:
When M10 = ON, the DRVA instruction executes absolute positioning on Y0 at the target position
20000 and the target frequency 2kHz. Y5 = OFF indicates positive direction.

Points to note:
1. Operation of absolute positioning:
