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

7 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)

PWM frequency
with SIEMENS
“SIMODRIVE”
inverters
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
N
are defined for these frequencies. If power
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:

or power modules.
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.
