7 CONTROL SUB FUNCTIONS
7.9 Other Functions
Control precautions
• The deceleration start flag function is valid for the control methods of 1-axis linear control, 2-axis linear interpolation control,
3-axis linear interpolation control, 4-axis linear interpolation control, speed-position switching control, and position-speed
switching control. For the linear interpolation control, this function is valid only for the reference axis. (
MELSEC iQ-R
Positioning Module User's Manual (Startup))
• The deceleration start flag does not turn on when the operation pattern is Continuous positioning control or Continuous
path control.
• The deceleration start flag function is invalid for the OPR operation, JOG operation, inching operation, manual pulse
generator operation, and during the deceleration by a stop signal.
• The deceleration start flag does not turn on when the deceleration is performed by the speed change or override.
• If the target position change is performed while Deceleration start flag is on, the deceleration start flag remains on.
• When the movement direction is reversed by the target position change, the deceleration start flag turns on.
• During the position control of the position-speed switching control, Deceleration start flag is turned on by the automatic
deceleration. Deceleration start flag remains ON if the control is switched to the speed control by Position-speed switching
signal after Deceleration start flag has turned ON.
• If the condition start in a block start is not started since the condition is not satisfied, Deceleration start flag turns on as long
as [Da.11] Shape is End.
• When a continuous operation interrupt request is issued, Deceleration start flag turns on at the start of the deceleration of
the positioning data being executed.
Setting method
To use the deceleration start flag function, set 1 to the following control data to using a program. The settings are validated at
the rising edge (when turned off and on) of PLC READY signal [Y0].
For details on the settings, refer to the following.
