Operands:
S
1
: Number of pulses (relative positioning) S
2
: Pulse output frequency D
1
: Pulse output device
D
2
: Direction signal output
Explanations:
1. The instruction only supports the pulse output type: Pulse + Direction.
2. S
1
is the number of pulses (relative 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 ~ 100,000Hz.
4. D
1
is the pulse output device. It can designate CH0 (Y0) and CH1 (Y2).
5. D
2
is the direction signal output device. It can designate CH0 (Y1) and CH1 (Y3).
6. The operation of D
2
corresponds to the “+” or “-“ of S. When S is “+”, D
2
will be OFF; when S is
“-“, D
2
will be ON. D
2
will not be OFF immediately after pulse output completion and will be
OFF when the drive contact is OFF.
7. The set value in S
1
is the relative position of
- current position (32-bit data) of CH0 (Y0, Y1) which is stored in D1031(high), D1030 (low)
- current position (32-bit data) of CH1 (Y2, Y3) which is stored in D1337(high), D1336 (low).
In reverse direction pulse output, value in (D1031, D1330) and (D1336, D1337) decreases.
8. D1343 (D1353) is the ramp up/down time setting of CH0 (CH1). Available range: 20 ~
32,767ms. Default: 100ms. PLC will take the upper/lower bound value as the set value when
specified value exceeds the available range.
9. D1340 (D1352) is start/end frequency setting of CH0 (CH1). Available range: 6 to 100,000Hz.
PLC will take the upper/lower bound value as the set value when specified value exceeds the
available range.
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..
