1 PRODUCT OUTLINE
(d) The zero point return control has been strengthened.
1) The near-point dog method (one type), stopper stop method (three
types), and count method (two types) zero point return methods have
been prepared as the "machine zero point return" zero point return
method.
2) To realize zero point return control to the machine zero point from a
random position, the zero point return retry function has been prepared.
(The machine zero point is the position used as the start point for
control such as positioning control. The machine zero point is
established with the machine zero point return in item 1) above.)
(e) Automatic trapezoidal acceleration/deceleration and S-curve
acceleration/deceleration have been prepared as the
acceleration/deceleration methods. The user can select from automatic
trapezoidal acceleration/deceleration or S-curve acceleration/deceleration.
(3) High-speed starting process
To quicken the process when starting positioning, the start processing time has
been reduced to 20ms.
When operation using simultaneous start function or interpolation operation is
executed, no start delay is generated between the target axes.
(Example) When operation is started with the simultaneous start function for axes
1 and 3: No start delay between axes 1 and 3.
When interpolation operation is started for axes 2 and axis 3: No start
delay between axes 2 and 3.
(4) High-speed pulse output and long distance with drive unit
(a) The AD75 has a differential driver and open collector pulse output interface.
Connect to either according to the type of drive unit.
(b) When connected to the differential driver, the speed and distance have
been increased.
• When connected to differential driver : 400kpps, max. 10m,
• When connected to open collector : 200kpps, max. 2m
(5) Easy maintenance
The maintenance of the AD75 has been improved with the following matters.
(a) The various data, such as the positioning data and parameters, are stored
on a flash ROM in the AD75.
This allows the data to be held without a battery.
(b) The error display, machine system input and zero point input state can be
confirmed with the 17-segment display.
(c) The primary diagnosis has been improved by detailing the error details.
(d) Up to 16 history items each for the error and warning information can be
held, so the details of the errors and warnings that have occurred can be
confirmed easily.
