Deceleration Start Flag Function - Mitsubishi Electric RD77MS2 User Manual

Deceleration start flag function

The "deceleration start flag function" turns ON the flag when the constant speed status or acceleration status switches to the
deceleration status during position control whose operation pattern is "Positioning complete". This function can be used as a
signal to start the operation to be performed by other equipment at each end of position control or to perform preparatory
operation, etc. for the next position control.
Control details
When deceleration for a stop is started in the position control whose operation pattern is "Positioning complete", "1" is stored
into "[Md.48] Deceleration start flag". When the next operation start is made or the manual pulse generator operation enable
status is gained, "0" is stored. (Reference to the figure below)
■Start made with positioning data No. specified
[Md.48] Deceleration start flag 0
■Block start
At a block start, this function is valid for only the position control whose operation pattern is "Positioning complete" at the point
whose shape has been set to "End". (Reference to the figure below)
The following table indicates the operation of the deceleration start flag in the case of the following block start data and
positioning data.
