The following table lists the functions of the QD70D.
(Read "SECTION 2 CONTROL DETAILS AND SETTING" for details of the functions.)
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 QD70D using machine OPR control.
Allows machine zero return from any given position.
Even if the work is located beyond the origin, machine zero
return will be automatically performed.
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.
The speed can be changed at any given time point during
control.
This function is valid during position control with operation
pattern set to "Positioning termination", during speed control
in the speed-position switching control or during JOG
operation.
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.
The positioning address or movement amount can be
changed at any given time point during control.
This function is valid during position control with operation
pattern set to "Positioning termination".
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.
