9 Application Instructions API 150-199 Y5). - The 32-bit data stored in the present value registers D1378 (high word) and D1377 (low word) of CH3 (Y5, Y6). - When in backward direction, the content in the present value register will decrease. 10. For SC series MPU, S 1 is the 32-bit data stored in the present value registers D1348 (low word) and D1349 (high word) of CH0 (Y10) or the 32-bit data stored in the present value registers D1350 (low word) and D1351 (high word) of CH1 (Y11). When in backward direction, the content in the present value register will decrease. When the program goes from STOP to RUN or from RUN to STOP, the content in the present value register will remain unchanged.

11. When DRVI instruction is executing pulse output, you cannot change the content of all operands. The changes will be valid next time when DRVI instruction is enabled. 12. For EH/EH2/SV/EH3/SV2 series MPU, when the drive contact of DRVI instruction is Off, even the indication flag M1336 sent by CH0 pulses, M1337 sent by CH1 pulses, M1522 sent by CH2 pulses and M1523 sent by CH3 pulses are “On”, DRVI instruction will not be driven again. 13. When the absolute value of the input frequency of DDRVI insturction in EH/EH2/SV/EH3/SV2 series MPU is larger than 200kHz, the output will be operated at 200kHz.

When the absolute value of the input frequency is smaller than 10Hz, the output will be operated at 10Hz. 14. D1343 (D1353) is for setting up the time of the first acceleartion segment and last deceleration segment of CH0 (CH1). The acceleration and deceleration time of EH/EH2/SV/EH3/SV2 series MPU is 1 ~ 10,000ms. The output will be operated for the default 100ms if the time is longer than 10,000ms. The time range for SC series MPU is 50 ~ 20,000ms. The output will be operated for 20,000ms or 50ms if the time set is longer than 20,000ms or shorter than 50ms. 15. D1340 (D1352) is for setting up the start/end frequency of Y10 (Y11).

If S 2 is less than or equals start/end frequency, the pulse output frequency will be executed by the start/end frequency. 16. For EH/EH2/SV/EH3/SV2 series MPU, M1305 (M1306) is the direction signal of CH0 (CH1). When S 1 is a positive number, the output will be operated in a forward direction and M1305 (M1306) will be Off. When S 1 is a negative number, the output will be operated in a backward direction and M1305 (M1306) will be On. Program Example: When M10= On, Y0 will output 20,000 pulses (relative designation) at 2kHz. Y5 = On indicates the pulses are executed in forward direction.
