a) Using Y10 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” M1334.
The time from executing planned deceleration to the end of pulse output: The time set in D1343 (for
acceleration/deceleration)
The solid lines in the figure below are the originally planned routes and the dotted lines refer to the routes
after planned deceleration is executed.

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” M1334.(Because PLSY does not have acceleration/deceleration setting, M1334 does not need to
be set in PLSY)
The time from executing output shutdown to the end of pulse output: Max. 1 scan cycle.
The solid lines in the figure below are the originally planned routes and the dotted lines refer to the routes
after output shutdown is executed.

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.
