Operands:
S
1
: Number of output pulses (absolute designation) S
2
: Pulse output frequency D
1
: Pulse output device
(please use transistor output module) D
2
: Output device for the signal of rotation direction

of SC series MPU only support device K, H and D.
3. Flag: see remarks of API 158 DRVI for more details.
4. S
1
is the number of output pulses (absolute designation). For EH/EH2/SV series MPU, the 16-bit instruction
can designate the range -32,768 ~ +32,767. The range designated by 32-bit instruction is -2,147,483,648 ~
+2,147,483,647. For SC series MPU, the 32-bit instruction can designate the range -2,147,483,648 ~
+2,147,483,647. “+/-” signs indicate forward/backward directions.
5. S
2
is the designated pulse output frequency. For EH/EH2/SV series MPU, the 16-bit instruction can designate
its range 10 ~ 32,767Hz. The range designated by 32-bit instruction is 10 ~ 200,000Hz. For SC series MPU,
the 32-bit instruction can designate the range 100 ~ 100,000Hz.
6. EH series MPU has two groups of A/B phase pulse output, CH0 (Y0, Y1) and CH1 (Y2, Y3). EH2/SV series
MPU has four groups of A/B phase pulse output, CH0 (Y0, Y1), CH1 (Y2, Y3), CH2 (Y4, Y5) and CH3 (Y6, Y7).
See remarks for the setup methods.

8. When S
1
is larger than the current relative position, D
2
will be Off; when S
1
is smaller than the current relative
position, D
2
will be On. D
2
will not be Off immediately after the pulse output is over; it will be Off only when the
drive contact of the instruction turns Off.
