7 Application Instructions API 50-99 S +2: Total time for operation (unit: ms) D1343: Ramp-up time (unit: ms) D1348: Ramp-down time (unit: ms) D +0, D +1: Optimal max output frequency (unit: Hz) (32-bit) D +2: Optimal start frequency (Unit: Hz) n : Reserved Whether the ramp-up time is equal to the ramp-down time depends on the setting of M1534. If the ramp-up time is not equal to the ramp-down time, there will be 30 sections of acceleration, and 30 sections of deceleration. If the ramp-up time is equal to the ramp-down time, there will be 60 sections of acceleration, and 60 sections of decelerations. Explanation on operands:
(For DVP-SV2 series PLCs whose version is 1.40 or below) S +0, S +1: Total number of pulses for operation (32-bit) S +2: Total time for operation (unit: ms) S +3: Ramp-up time (unit: ms) S +4: Ramp-down time (unit: ms) D +0, D +1: Optimal max output frequency (unit: Hz) (32-bit) D +2: Optimal start frequency (Unit: Hz) n : Reserved The ramp-up time is equal to the ramp-down time. There are 30 sections of acceleration, and 30 sections of deceleration. Explanation on operands: (For DVP-EH3 series PLCs whose version is 1.62 (or above) and DVP-SV2 series PLCs whose version is 1.40 (or above) S +0, S +1: Total number of pulses for operation (32-bit) S +2: Total time for operation (unit: ms) S +3:
Ramp-up time (unit: ms) S +4: Ramp-down time (unit: ms) D +0, D +1: Optimal max output frequency (unit: Hz) (32-bit) D +2: Optimal start frequency (Unit: Hz) n : Reserved If S +3 is equal to S +4, the ramp-up time is equal to the ramp-down time, and there are 60 sections of acceleration, and 60 sections of deceleration. If S +3 is not equal to S +4, the ramp-up time is not equal to the ramp-down time, and there are 30 sections of acceleration, and 60 sections of deceleration. K11: Conversion from Local Time to Local Sidereal Time Unlike the common local time defined by time zones, local sidereal time is calculated based on actual DVP-PLC APPLICATION MANUAL 7-65
