20 Interface to the Drives

20.1 Digital PWM Interface

20.1.1 Introduction

The position, speed and current controllers are located in the HEIDENHAIN control.
The "result" of the position, speed and current control is pulse-width modulated.
Via PWM interfaces (PWM = pulse-width-modulation) digital servo amplifiers are controlled.
Digital drive systems are also referred to as inverter systems.
For digital drives three-phase ac motors are used.
The most important motors are:
Following PWM interfaces are located on the CC 422 or CC 424 (B)
PWM outputs
(every digital axis/spindle has its own PWM ribbon-cable connector):
MP 100 is read from the right to the left and contains the information which axis is the first, the
Assignment of the
second, the third axis, etc.

Asynchronous motors (e.g., HEIDENHAIN QAN spindle motors)
Linear motors
Torque motors
X51 to X56
X57 to X64 (depending on the expansion stage)
Caution
MP 100 must not be changed!
