Specifications

1 - 2

(d) Two acceleration/deceleration methods (selectable by users) are provided:

automatic trapezoidal acceleration/deceleration and S-curve

acceleration/deceleration. (The S-curve acceleration/deceleration control is

disabled if stepping motors are used.)

(3) Quick startup

A positioning operation starts up quickly taking as little as 6 ms to 7 ms.

When operation using simultaneous start function (independent operation,

interpolation operation) is executed, the axes start without delay. (Quick startup of

the AD75 takes 20ms.)

(4) Faster pulse output and longer maximum distance to drive unit

The differential driver type modules (QD75D1, QD75D2 and QD75D4) incorporate

the following improvements in the pulse output speed and the maximum distance

to the drive unit.

•

For the differential driver type module, QD75D1/QD75D2/QD75D4:

1 Mpulse/s, 10m max.

•

For the open collector type, QD75P1/QD75P2/QD75P4:

200 kpulse/s, 2m max. (For the differential driver type module AD75: 400

kpulse/s, 10m max.)

(5) Easy maintenance

Each QD75 positioning module incorporates the following improvements in

maintainability:

(a) Data such as the positioning data and parameters can be stored on a flash

ROM inside the QD75, eliminating the need of a battery for retaining data.

(b) Error contents are classified in more detail to facilitate the initial fault

diagnosis.

confirmation of error and warning histories.

(6) Support of intelligent function module dedicated instructions

Dedicated instructions such as the positioning start instruction and teaching

instruction are provided.

The use of such dedicated instruction simplifies sequence programs.

(7) Support of setting, monitoring and testing with a software package for positioning

Using a software package for positioning (SW

D5C-QD75P), the user can set the

QD75 parameters and positioning data without considering the buffer memory

addresses.

Moreover, the software package has a test function which allows the user to check

the wiring before creating a sequence program for positioning control, or to test

the QD75 using set parameters and positioning data for checking their integrity.

The control monitor function allows the user to debug programs efficiently.
