2 Functions of Devices in DVP-PLC Mode 3 – Immediate output shutdown Applicable to: DDRVI, DDRVA, PLSY instructions Criteria for executing immediate output shutdown: M1310 = On (set before executing the instruction) and the criteria triggers set in X10 (D1166 = K0 refers to rising-edge; D1166 = K1 refers to falling-edge) The time from executing immediate output shutdown to the end of pulse output: Max. 1 pulse time. The solid lines in the figure below are the originally planned routes and the dotted lines refer to the routes after X10 is triggered. Frequency X10 triggered Target frequency Start frequency D1340 Time Max.
Stop time = 1 pulse time b) Using Y11 pulse output Mode 1 – Planned deceleration Applicable to: DDRVI and DDRVA instructions Criteria for executing planned deceleration: Shut down the criteria contact for pulse output instruction and turn “Off” M1335. acceleration/deceleration) The time from executing planned deceleration to the end of pulse output: The time set in D1353 (for Mode 2 – Output shutdown Applicable to: DDRVI, DDRVA, PLSY instructions Criteria for executing output shutdown: Shut down the criteria contact for pulse output instruction and turn “On” M1335.
(Because PLSY does not have acceleration/deceleration setting, M1335 does not need to be set in PLSY) The time from executing output shutdown to the end of pulse output: Max. 1 scan cycle. Mode 3 – Immediate output shutdown Applicable to: DDRVI, DDRVA, PLSY instructions Criteria for executing immediate output shutdown: M1311 = On (set before executing the instruction) and the criteria triggers set in X11 (D1167 = K0 refers to rising-edge; D1167 = K1 refers to falling-edge) The time from executing immediate output shutdown to the end of pulse output: Max. 1 pulse time. 3. Note:
a) The execution criteria M1334 and M1335 for mode 1 and 2 have to be set before executing pulse output shutdown instruction. The execution criteria M1310, M1311 and trigger criteria D1166, D1167 for mode 3 have to be set before the pulse output instruction is executed. b) In mode 3 (immediate output shutdown), Y10 can only be used with X10 and Y11 with X11. c) When using X10 or X11 in mode 3, DO NOT use X10 or X11 as the input high-speed counter.
