HEIDENHAIN inverters:
UE 2xx, UE 2xxB, UV 130: 565 V

The HEIDENHAIN TNC 426 PB/M, TNC 430 PA/M controls and the
HEIDENHAIN inverters work with a PWM frequency of 5000 Hz:

In all MP2180.x and in MP2181, enter the PWM frequency 5000 Hz (or input
value 0)
MP2180.0-8 PWM frequency of the axes
Input:
3000 to 7000 [Hz]
0 = 5000 Hz (for HEIDENHAIN inverters)
MP2181
PWM frequency of the spindle
Input:
3000 to 7000 [Hz]
0 = 5000 Hz (for HEIDENHAIN inverters)
Note
The values between 1 Hz and 2999 Hz and between 7001 Hz and
10 000 Hz cause the DSP error message C013 PWM frequency incorrect
after the acknowledgement of the POWER INTERRUPTION message.

In all MP2180.x and in MP2181, enter the PWM frequency 4000 Hz.
The HEIDENHAIN TNC 426 PB/M and TNC 430 PA/M controls work with a
PWM frequency of 5 kHz. SIEMENS power modules are normally driven with
a PWM frequency of 3.2 kHz (spindle) and 4 kHz (axes).
The rated current values I
modules are operated with a higher PWM frequency (5 kHz), high
temperatures can be caused in these modules in some cases.
This applies particularly to these SIEMENS power modules:
n
6SN1123-1AA00-0CA0 (as axis module)
n
6SN1123-1AB00-0CA0 (as axis module)
Machines that are not under full load do not exceed the maximum permissible
temperature.
There are two ways to prevent the undesired heating:
