7 CONTROL SUB FUNCTIONS
7.1 Overview of Sub Functions
*1 The near pass function is featured as standard and is valid only when the continuous path control for position control operations is set.
The function cannot be set to be invalid with parameters.
*2 To perform Torque limit, a D/A converter module and a drive unit capable of the torque limit command with an analog voltage must be
needed.
*3 An I/O module with arbitrary number of points and a drive unit capable of configuring an absolute position detection system (which is a
Mitsubishi General-Purpose AC Servo and has an absolute position detection function (absolute position data transfer protocol)
equivalent to that of MR-J3-
 A) are needed.
Function related to
positioning stop Stop command
processing for
deceleration stop
function Selects a deceleration curve when a stop cause occurs during the deceleration stop processing to speed 0.
Continuous operation
interrupt function Interrupts the continuous operation. When this request is accepted, the operation will stop at the completion
of the positioning data being executed.
Step function Temporarily stops the operation to check the positioning operation during debugging and other operation.
The operation can be stopped for each Automatic deceleration or Positioning data.
Other functions Skip function Pauses (decelerates to stop) the positioning being executed when Skip signal is input, and performs the
next positioning.
M code output function Issues a command for a subsidiary work (such as stopping clamps or drills and changing tools)
corresponding to each M code number (0 to 65535) that can be set to each positioning data.
Teaching function Stores the address positioned with the manual control in [Da.6] Positioning address/movement amount of
the specified positioning data No.
Command in-position
function Calculates the remaining distance for the RD75 to reach the positioning stop position for each automatic
deceleration, and sets Command in-position flag to 1 when the value is less than the set value. When
performing another subsidiary work before the control ends, use this function as a trigger for the subsidiary
work.
Acceleration/
deceleration processing
function Adjusts acceleration/deceleration (acceleration/deceleration time and curve) of the control.
Deceleration start flag
function To inform the stop timing, this function turns on Deceleration start flag when the speed status is changed
from the constant speed or acceleration to deceleration during the position control whose operation pattern
is Positioning complete.
During uncompleted
OPR operation setting
function Sets whether or not to execute the positioning control when OPR request flag is on.
Interrupt function Generates an interrupt request to the CPU module when an interrupt factor is detected, and starts an
interrupt program.
