*1 The near pass function is featured as standard and is valid only for position control. It cannot be set to be invalid with
parameters.
*2 Using "Torque limit function" requires a "D/A conversion module" and a "drive unit capable of torque limit command with
analog voltage".
*3 An I/O module (or general-purpose I/O function of LCPU) with arbitrary number of points and "the drive unit capable of
configuring an absolute position detection system, which is a Mitsubishi Electric General-Purpose AC Servo and has an
absolute position detection function (absolute position data transference protocol) equivalent to that of MR-J3-
 A," are
required to execute the "absolute position restoration function".
Other Functions
Step function
This function temporarily stops the operation to confirm the
positioning operation during debugging, etc.
The operation can be stopped at each "automatic deceleration" or
"positioning data".
Page 572, Section 12.7.1
Skip function
This function stops (decelerates to a stop) the positioning being
executed when the skip signal is input, and carries out the next
positioning.
Page 577, Section 12.7.2
M code output function
This function issues a command for a sub work (clamp or drill
stop, tool change, etc.) corresponding to the M code No. (0 to
65535) that can be set for positioning data.
Page 580, Section 12.7.3
Teaching function
This function stores the address positioned with manual control
into the positioning address having the designated positioning
data No. ([Cd.39]).
Page 586, Section 12.7.4
Command in-position function
At each automatic deceleration, this function calculates the
remaining distance for the LD75 to reach the positioning stop
position. When the value is less than the set value, the
"command in-position flag" is set to "1".
When using another auxiliary work before ending the control, use
this function as a trigger for the sub work.
Page 593, Section 12.7.5
Acceleration/deceleration process
function This function adjusts the control acceleration/deceleration.
(acceleration/deceleration time and curve).
Page 596, Section 12.7.6
Continuous operation interrupt
function
This function interrupts continuous operation. When this request
is accepted, the operation stops when the execution of the
current positioning data is completed.
Page 296, Section 6.5.4
Pre-reading start function This function shortens the virtual start time. Page 598, Section 12.7.7
Deceleration start flag function
Function that 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", to make the stop timing known.
Page 602, Section 12.7.8
Stop command processing for
deceleration stop function Function that selects a deceleration curve when a stop cause
occurs during deceleration stop processing to speed 0.
