Remaining Distance Operation - Mitsubishi Electric MELSEC iQ-F FX5 User Manual

Remaining distance operation

When pulse output is stopped by the pulse decelerate and stop command during positioning instruction operation and the
remaining distance operation enabled is ON, the remaining distance operation ready status is acquired. (Page 62
Remaining distance operation, Page 38 Pulse decelerate and stop) When the pulse decelerate and stop command turns off,
the remaining distance operation starts. Or if the external start signal (when enabled) is detected, remaining transfer amount
from deceleration stop is output. After the remaining distance operation is completed, the complete flag turns on. (Page

Changes to the positioning address and command speed during positioning operation are valid until the system starts
deceleration stop under the pulse decelerate and stop command. After deceleration stop, changes are applied when the
positioning instruction is started again.
When dwell time is set, and the remaining distance operation start command is turned on immediately after deceleration stop,
remaining distance operation is started regardless of the dwell time.
