> System demand
Along with modern manufacture industry swift and violent
development, people to control system request more and more high:
On the one hand, requests the realization multiple spindle
synchronization control in the identical system the situation to be
more and more many; On the other hand, the control system
occupies the space requests more and more slightly, this request
control system few matches the line to be better.
Insults the China solution
In view of this kind of demand, Ling Hua proposed the
integrity solution. Ling Hua has used in the control system
based on Mitsubishi SSCNET the serial movement control technology PCI
- 8,372 movements control card.
The system principle of work following chart shows, Host PC
penetrates PCI Bus under DSP which embraces to the movement control
various axes position and the velocity curve order. DSP
transforms Cheng Gezhou after the operation the position order,
divides under the cycle to order the servo driver. Is borrowing
operation function formidable DSP, various types complex motor
function all may achieve, like multiple spindle makes up, the
continual motion, the movement changes the speed or the vertex
position and so on. In order to achieve true "position endless
loop control", embraces also may accept exterior increase type encoder
to return gives, after but outputs the SSCNET order, so may overcome
the position error which the mechanical drive module creates.
System appraisal
Revolves the movement control system which the PCI - 8,372
movements control cards builds to have the following superiority:
1. uses the SSCNET technology, the position error which
eliminates the tradition servosystem when to carry on multiple spindle
control appears, the realization multiple spindle between absolute
synchronization control;
2. controls axis numbers have the very big expansion space, each
PCI - 8,372 movements control cards may control 12 axes, if the week
number surpasses 12, then may use increases the control card the
method solution, may simultaneously apply 15 PCI - 8,372 movements
control cards in a system, between the multi- cards may realize the
synchronous operation;
3. PCI - 8,372 may support the many kinds of operating system,
simultaneously has brought the simple Yi Yong function storehouse,
convenient user operation;
4. is the uniform allocation line is simple, saves the space,
the cost for the radio station equipment.
