(d) The zero point return control has been strengthened.
1) The near-point dog type (one type), stopper stop type (three types),
and count type (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-pattern
acceleration/deceleration have been prepared as the
acceleration/deceleration methods. The user can select from automatic
trapezoidal acceleration/deceleration or S-pattern acceleration/deceleration.
To quicken the process when starting positioning, the start processing time has
been reduced to 20ms.
During simultaneous starting (during independent operation, interpolation
operation), no delay is generated in the start between axes.
(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
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.
