Fig. 13.48 Operation of deceleration start flag at block start
[2] Precautions during control
(1) The deceleration start flag function is valid for the control method of "1-axis
linear control", "2-axis linear interpolation control", "3-axis linear interpolation
control", "4-axis linear interpolation control", "speed-position switching
control" or "position-speed switching control". (In the case of linear
interpolation control, the function is valid for only the reference axis.) Refer to
Section 3.2.5 "Combination of LD77MS main functions and sub functions".
(2) The deceleration start flag does not turn ON when the operation pattern is
"continuous positioning control" or "continuous path control".
(3) The deceleration start flag function is invalid for an OPR, JOG operation,
inching operation, manual pulse generator operation, speed-torque control
and deceleration made with a stop signal.
(4) The deceleration start flag does not turn ON when a speed change or
override is used to make deceleration.
(5) If a target position change is made while the deceleration start flag is ON, the
deceleration start flag remains ON.
