Description
Mechanically establishes the positioning control start
point using a near-point dog or stopper.
Positions a target to the OP address ( Md. 1 Current feed
value) stored in the QD70 using machine OPR control.
Positions a target using a linear path to the address set in
the positioning data or to the position designated with the
movement amount.
First, carries out speed control, and then carries out
position control (positioning control with designated
address or movement amount) by turning the "speed-
position switching signal" ON.
Changes the Current feed value ( Md. 1 ) to the address
set in the positioning data.
Outputs a pulse to drive unit while the JOG start signal is
ON.
If the command speed exceeds " Pr. 5 Speed limit value"
during control, this function limits the commanded speed
to within the " Pr. 5 Speed limit value" setting range.
This function changes the speed at any point during
speed control of speed-position switching control or
during JOG operation.
Set the new speed in the speed change buffer memory
( Pr. 7 New speed value), and change the speed with the
Speed change request ( Pr. 6 ).
If a command outside of the upper/lower limit stroke limit
setting range, set in the parameters, is issued, this
function will not execute positioning for that command.
This function adjusts the acceleration/deceleration
processing of control.
This function resumes positioning control during a stop of
the axis from where it had stopped.
This function changes the external I/O signal logic to
match the externally connected device.
It can be changed by making the intelligent function
module switch setting.
This function monitors the external I/O signal states using
GX Developer.
