Technical Field
The invention relates to the technical field of heavy numerical control machine tools, in particular to a DRIVE-CLIQ motor switching control system.
Background
For a heavy machine tool, machine tool accessories, particularly machine tool accessories with servo motors (such as servo rotary head, servo milling head and the like), can realize interpolation machining of servo axes, and are indispensable components of the heavy machine tool. The switching of the servo motors is involved in the replacement of the machine tool accessories with servo motors.
DRIVE-CLIQ is a network protocol developed by siemens on an ethernet basis, all elements using this interface having a unique DRIVE-CLIQ code, which is a number used to identify the element inside the siemens subsystem. Taking the servo motor as an example, two DRIVE-CLIQ motors with the same model are identified as two independent and unrelated motors by the system because the DRIVE-CLIQ codes are different.
When the DRIVE-CLIQ motor is switched, if the external connection motor is directly changed, system alarm is caused, and the machine tool cannot run. Therefore, the 840D SL system must recognize multiple DRIVE-CLIQ motors at the same time, and then implement motor switching via the motor selection function.
In practical applications, the above problems are solved, wherein one way is to select a motor with a non-DRIVE-CLIQ interface, but the disadvantage of this way is that the motor signal needs to be converted by the encoder module SMC20, which increases the cost accordingly; another way is to have a separate motor module for each DRIVE-CLIQ motor, which would increase the production cost virtually.
