2 Introduction
2.1 General Information

• HEIDENHAIN contouring controls are designed for use with milling, drilling and boring machines as well as machining centers. The TNC 426 PB/M, TNC 430 PA/M features integral digital drive control and controls the power stages via PWM signals. Integration of the drive controller in the TNC 426 PB/M, TNC 430 PA/M offers the following advantages:
• 
  All the software is contained centrally in the NC; this means that the individual components of the NC such as feed axes, spindle, NC or PLC are optimally matched.
• 
  High control quality, because the position controller, speed controller and current controller are combined into one unit.
• 
  The same functions are available for commissioning, optimizing and diagnosing feed drives as well as spindles. With the TNC 426 PB, up to five axes and spindle speeds of up to 12 000 rpm can be controlled digitally (option: 30 000 rpm). The TNC 430 PA supports up to 6 digitally controlled NC axes, 3 analog controlled secondary axes, and digitally controlled spindle speeds up to 30 000 rpm.
