3. HM5-4EH - 4 axis 100 MHz PWM clock
Modified so basic clock for PWM and interrupt rate is 100 MHz
ID/REV reads AA020004 (low half is # of axis), MCLK reads 100 MHz
I can send the source and bit files tommorow. (where?)
Peter, if the files are not too large (5Mb) you can email me the

Its limited to ~33 KHz at the moment (33.3 MHz PCI clock /1024)
It would be pretty easy to use the 50 MHz clock instead to the max would

OK so for the 5I20 I can change the PWM so it will go up to ~66 KHz instead
of
~33 KHz.
Peter, would changing to a max 66 kHz PWM frequency on the 5I20 simply
require a new fpga configuration to be compiled and downloaded to the
5I20, or does it require

Several EMC developers are planning on getting m5i20 boards in the near
future

But whats the dead time? If you are not using a closed loop current control,
(that is the controller PWM runs the HBridge directly) the dead time will
become a significant part of your 50 KHz cycle time leading to non-linearity
in PWM versus motor voltage. At least that

Hi All,
I'm considering using Jon Elson's PWM servo amplifiers with my Mesa
M5i20 servo card.
Jon tells me his amplifiers are optimized for 50 kHz PWM frequency. Does
anyone know in what range the PWM frequency is adjustable on the Mesa
M5i20 ?
The manual talks about 10-bit PWM with a 33MHz
11 matches
