80 HEIDENHAIN Technical Manual MANUALplus 620
2.4 General Information
The HEIDENHAIN MANUALplus 620 contouring control was conceived for
standard CNC lathes. The control has an integrated digital drive control and
drives the power modules through PWM signals.
Integrating the drive controllers in the MANUALplus 620 provides the
following benefits:
All the software is contained centrally in the NC; this means that the
individual components of the NC, such as feed axes, spindle, NC and 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.
The MANUALplus 620 supports lathes up to the following level:
1 slide (NC channel)
6 axes (X/Z/Y/U/V/W axis)
3 spindles (main spindle and opposing spindle, driven tool)
2 C axes (via main spindle drive or with separate drive)
The following diagram illustrates drive control with the use of a rotary encoder
for measuring the actual speed values and a linear encoder or angle encoder
for measuring the actual position values.
The MANUALplus 620 is based on HEIDENHAIN NCK, the software platform
for the HEIDENHAIN control family. Other controls with NCK are, for example,
the TNC 620, TNC 320 or the CNC PILOT 620.
The MC 6110T, the compact main computer of the MANUALplus 620, takes
up very little space, as it is housed in the operating console, directly behind the
integrated 12.1-inch TFT display.
