3 – 44 HEIDENHAIN Technical Manual TNC 426, TNC 430
3.6 Connecting the Motor Power Module
The LE 426 M and the LE 430 M can be operated with HEIDENHAIN and with
non-HEIDENHAIN inverter systems. The LE 426 PB and the LE 430 PA can
only be operated with non-HEIDENHAIN inverter systems.
For a description of the HEIDENHAIN inverter systems, refer to the Technical
Manual “Inverter Systems and Motors.” The components required for
operation of the LE with non-HEIDENHAIN inverter systems are described in
the manual “Technical Information for the Operation of SIMODRIVE and
POWER DRIVE Inverter Systems.”
