API 159 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 Explanations: 1. S 1 is the number of output pulses (absolute designation). For EH/EH2/SV/EH3/SV2 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. 2. S 2 is the designated pulse output frequency.
For EH/EH2/SV/EH3/SV2 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 24SV2 series MPU, the 16-bit instruction can designate its range 10 ~ 10,000Hz. The range designated by 32-bit instruction is 10 ~ 10,000Hz. For SC series MPU, the 32-bit instruction can designate the range 100 ~ 100,000Hz. 3. Pulse output device D 1 in different models 4. 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. If D 1 and D 2 in a 24SV2 series MPU are Y devices, Y10/Y11 and Y12/Y13 must be used. 5. For EH/EH2/SV/EH3/SV2 series MPU, S 1 is - The 32-bit data stored in the present value registers D1337 (high word) and D1336 (low word) of CH0 (Y0, Y1). - The 32-bit data stored in the present value registers D1339 (high word) and D1338 (low word) of CH1 (Y2, Y3). - The 32-bit data stored in the present value registers D1376 (high word) and D1375 (low word) of CH2 (Y4, Y5).
