TML Library: The TML Motion Libraries can work under Windows (32-bit and 64-bit versions available), or Linux operating system and can be included in an application developed under C/C++, C#, Visual Basic, Delphi Pascal, or LabVIEW. TML_Lib is a collection of high-level functions allowing to control, from a PC, the Technosoft intelligent drives and motors. The protocol is TML and communication can take place via RS232, CAN bus, Ethernet or USB.
Technosoft Motion Language (TML) programming language: Using the TML language, different operating modes, movement profiles, reference runs or the control of complex sequence programs can be graphically programmed and executed autonomously. The drive controllers can process analog and digital I / O signals, perform arithmetic and logical operations, and also exchange data and commands between the axes. Single-axis and multi-axis stand-alone applications can be easily implemented with self-created sequence programs, even without the use of a complex CANopen or EtherCAT master controller.
MotionChip ™ technology: The main core of all Technosoft servo controllers is the MotionChip ™ – an intelligent, freely programmable motion controller specially designed for complex motion control tasks. The MotionChip ™ offers the possibility to use the powerful digital signal processors (DSP) from Texas Instruments as an independent, intelligent unit. As a result, many tasks of a complex master control are solved directly by the MotionChip ™, so that the global function of a machine is relieved and the management of a master application can be optimized. All-important control functions of a controller such as a multitude of operating modes, PLC properties, protection and safety functions as well as support for the different interface and motor technologies are accommodated on the MotionChip ™, thus enabling flexible use in a wide variety of drive systems.
