2 Functions of Devices in DVP-PLC Usage restriction: Has to work with external interruptions, special M and special D. Other explanations: a) When this function is enabled, PLC will start to decelerate according to the set deceleration time. Even if the user does not set up the number of deceleration pulses (i.e. special D = 0), or the set number of pulses is less than the number planned for the deceleration time, PLC will still decelerate within the deceleration time. On the contrary, if the number of deceleration pulses is more than the planned number for the deceleration time, PLC will decelerate according to the number set in the special D. b) Range for deceleration time:
10 ~ 10,000ms c) There is mask interruption in CH0 high-speed output. When D1027/D1026 (32-bit) ≠ 0, the mask function will be enabled, i.e. X0 external interruption will not be activated when the number of output pulses is within the mask area. High-speed output CH0 ~ CH3 v.s. pause function of external input points X0 ~ X3: EH3/SV2 Application examples: When M0 turns from Off to On, Y0 will start to output pulses and wait for the external input interruption X0 to take place. When interruption signals occur in the acceleration section or the highest speed section during the output, Y0 will immediately decelerate and stop the output after 100ms, and M1538 = On.
When M1538 = On, the user can reset (RST) M1156, and PLC will start to output the remaining pulses. When all the target pulses are completed, M1029 will be On. If the external interruption occurs in the planned deceleration area, the output will not decelerate or set M1538 to On. b) Example 1: Immediately decelerate and pause within deceleration time Application: When external interruptions occur, the high-speed output has to achieve deceleration and single-axis motion control. pause within the designated deceleration time.
