Upper limit switch
(FLS)/lower limit switch
(RLS) function
A workpiece is returned to an original point following an OPR start
command, and the current value is corrected as an OP address after the
completion of OPR.
Positioning Positioning is executed from the current position to a specified position at
control a specified speed.
Positioning is executed to the address specified with "
Two-phase
trapezoidal
address P1" at "
positioning
specified with "
control
speed V2" by one positioning start signal.
Operation starts according to the positioning speed set beforehand by
one positioning start signal, then the operation switches to position
control by Speed-position switching command signal (CHANGE).
If the operation stopped by Stop signal after the input of Speed-position
switching command signal (CHANGE), the positioning can be continued
by requesting a restart.
In addition, the positioning address (movement amount) can be changed
if it is before the input of Speed-position switching command signal
(CHANGE).
Positioning is executed in the specified direction at specified speed while
a JOG operation command is on. Turning on the signal starts operation
at a specified speed and speed control operation can be continued until a
stop signal is input.
This function controls moving distance and speed by
multiplying command pulse output of the QD73A1.
This function limits command speed to the value set in
" Speed limit value".
Pr.5
This function controls operation not to execute positioning
when a command that moves the workpiece outside the
specified stroke limit range is given.
This function decelerates and stops operation according to the
detection on limit switches placed at the upper and lower
stroke limits.
