Data Required For Major Positioning Control - Mitsubishi Electric MELSEC iQ-F Series FX5 User Manual

Major positioning control
Other controls
*1 "2-axis linear interpolation control", "2-axis fixed-feed control", "2-axis circular interpolation control", and "2-axis speed control" use the
motor set in the direction of the two axes to implement control to describe linear or circular paths.
This type of control is called interpolation control. (Page 108 Interpolation control)

Description
A control method that is not implemented. When the NOP instruction is
set, the operation of the next data starts and this instruction is not
implemented.
Changes the value in "[Md.20] Current feed value" to the address set in
the positioning data.
The following two methods can be used. (Machine feed value cannot be
changed.)
• Current value change using the control method
• Current value change using the start No. for a current value change
(No. 9003)
Unconditionally or conditionally jumps to the specified positioning data No.
Implements repetition control with the LOOP to LEND instructions.
Returns to the beginning of the repetition control with LOOP to LEND
instructions. When the repetition of the instructions has been completed
for the specified number of times, the operation of the next positioning
data starts.
Setting detail
Set an operation pattern for the continuous positioning data (example: Positioning data No.1 to
3). (Page 95 Operation pattern of major positioning control)
Set a control method defined for Major positioning control used. (Page 93 Overview of the
Major Positioning Controls)
Select and set an acceleration time at the start of the control. (Select one from four values set in
[Pr.9], [Pr.25], [Pr.26], and [Pr.27] as the acceleration time.)
Select and set a deceleration time at the stop of the control. (Select one from four values set in
[Pr.10], [Pr.28], [Pr.29], and [Pr.30] as the deceleration time.)
Set a target axis (partner axis) for the 2-axis interpolation control. (Page 108 Interpolation
control)
Set a target value for the position control. (Page 102 Specifying the positioning address)
Set a sub point or a center point address for the circular interpolation control.
Set the speed at the execution of the control.
The time from when the command pulse output is completed to when Positioning complete
signal is turned on. Set this time to absorb the delay of machine systems to the command, such
as the delay (deviation) of the servo system.
Set an M code to issue a command for a subsidiary work (such as stopping clamps or drills and
changing tools) corresponding to each M code number that can be related to the implementation
of the positioning data.
Set the M code ON signal output timing for each positioning data.
Set the ABS direction in degrees for each positioning data.
Set the interpolation speed specification method for each positioning data.
