2 Functions of Devices in DVP-PLC 2. Actions of program type pulse output pause function (with no deceleration): Frequency Target frequency Start/end frequency Acceleration time Max. stop time: 1 scan cycle Deceleration time Number of pulses Applicable instructions: DRVI/DDRVI/DRVA/DDRVA/PLSR/DPLSR Applicable model/firmware version: EH2, EH3/SV2 v1.4, SV v1.5 (and their later versions) During the pulse output, force On M1308 will stop the output, and force Off M1308 will start the output of remaining pulses. The max. stop time inaccuracy in this pause function is 1 scan cycle. High-speed output CH0 ~ CH3 v.s. pause function of pause flags: 3.
Special M and special D registers for SV V1.4 and later versions when conducting deceleration to pausing output (for the ongoing high-speed pulse output encountering interruption signals), mask and mark. DVP-PLC Application Manual 2-115 M1308=ON Pulse output com M1029 = On M1308=OFF Tim Nu Flag Pause flag Channel CH0 M1308 CH1 M1309 CH2 M1310 CH3 M1311 Device No. Function M1308 Off -> On: 1st group of CH0 (Y0, Y1) high-speed pulse output immediately pauses. On -> Off: Complete the remaining number of output pulses M1309 Off -> On: 2nd group of CH1 (Y2, Y3) high-speed pulse output immediately pauses. On -> Off: Complete the remaining number of output pulses M1310 Off -> On:
3rd group of CH2 (Y4, Y5) high-speed pulse output immediately pauses. On -> Off: Complete the remaining number of output pulses M1311 Off -> On: 4th group of CH3 (Y6, Y7) high-speed pulse output immediately pauses. On -> Off: Complete the remaining number of output pulses M1156 Enable X0 interruption to trigger immediate decelerating and pausing CH0 high-speed output.
(When M1156 is enabled and M1538 = On, simply clear M1156 to finish sending out the remaining output pulses.) M1157 Enable X1 interruption to trigger immediate decelerating and pausing CH1 high-speed output M1158 Enable X2 interruption to trigger immediate decelerating and pausing CH2 high-speed output M1159 Enable X3 interruption to trigger immediate decelerating and pausing CH3 high-speed output M1538 CH0 pause status M1539 CH1 pause status M1540 CH2 pause status M1541 CH3 pause status D1026 When ≠ 0, enabling DRVI and PLSR instructions to work with X0 (mask) interruption.
