Delta DVP-EX2

3. Instruction Set
3-493
In reverse direction pulse output, value in (D1031, D1330) and (D1336, D1337) decreases.
11. D1343 (D1353) is the ramp up/down time (between start frequency and pulse output
frequency) setting of CH0 (CH1). Available range: 20 ~ 32,767ms. Default: 100ms. PLC will
take 20ms as the set value when specified value is below 20ms or above 32,767ms.
12. D1340 (D1352) is start/end frequency setting of CH0 (CH1). Available range: 6 ~ 32,767Hz.
PLC will take the start/end frequency as the pulse output frequency when pulse output
frequency S
2
is smaller or equals the start/end frequency.
13. 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.
14. 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.
15. 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.
16. DRVA/DDRVA instructions do NOT support Alignment Mark and Mask function.
17. When M1334 or M1335 is enabled, execute API158 DDRVI instruction on CH0 (CH1) to
ramp-down when the conditional contacts are closed. After the conditional contacts are closed,
if you need to use the flags M1334/M1335 to stop the deceleration, you need to enable the
flags M1334/M1335 again. This function is available for the followings:

Explanations (Applicable to EC5 Series):
1. The instruction only supports the pulse output type: Pulse + Direction.
2. S
1
is the number of pulses (Absolute positioning). Available range: -2,147,483,648 ~
+2,147,483,647. “+/-” signs indicate forward and reverse direction.
3. S
2
is the pulse output frequency. Available range: 6 ~ 50,000Hz.
4. S
1
is the target position for absolute positioning. The actual number of output pulses (S
1
–
current position) will be calculated by PLC. When the result is positive, pulse output executes
forward operation, i.e. D
2
= OFF; when the results is negative, pulse output executes reverse
operation, i.e. D
2
= ON.
5. The instruction DRVA shares the same table of supported special D and special M, refer to
instruction DRVI for more information.
