a) Applicable to: DDRVI, DDRVA, PLSY instructions
b) Criteria for executing output shutdown: Shut down the criteria contact for pulse output
instruction and set M1334 as ON (Because PLSY does not have speeding up/slowing down
setting, M1334 does not need to be set in PLSY)
c) The time from executing output shutdown to the end of pulse output: Max. 1 scan cycle.
d) Explanation: The solid lines in figure 2 are the originally planned routes and the dotted lines
refer to the routes after output shutdown is executed.
Max. Stop time=1 scan cycle
Instruction shut down and M1334=OFF

Mode 3 – Immediate output shutdown
a) Applicable to: DDRVI, DDRVA, PLSY instructions
b) Criteria for executing immediate output shutdown: M1310 =ON (set before activating the
instruction) and the criteria triggers set in X10 (D1166=K0 refers to rising-edge; D1166=K1
refers to falling-edge)
c) The time from executing immediate output shutdown to the end of pulse output: Max. 1 pulse
time.
d) Explanation: The solid lines in figure 3 are the originally planned routes and the dotted lines
refer to the routes after X10 is triggered.

3. High-speed output pulse stop mode use Y11 pulse output
Mode 1 – Planned slowing down
a) Applicable to: DDRVI and DDRVA instruction
b) Criteria for executing planned slowing down: Shut down the criteria contact for pulse output
instruction and set M1335 as OFF
c) The time from executing planned slowing down to the end of pulse output: The time set in
D1353 (speeding up/slowing down time)
Mode 2 – Output shutdown
a) Applicable to: DDRVI, DDRVA, PLSY instructions
