Buongiorno, avrei un problema con questa scheda, praticamente ho sostituito mosftet, diodo e scr.
Praticamente alimentandola da Banco l’elettronica funziona, quando la vado a collegare al Tapis roulant, mi salta il differenziale.
volevo sapere sul dissipatore in alluminio, l’SCR è provvisto di dissipatore isolante dall’alluminio?
Allego foto della scheda

Mod translation.
Good morning, I have a problem with this board. I basically replaced the MOSFET, diode, and SCR.
When I power it from the bench, the electronics work fine. However, when I connect it to the treadmill, the differential trips.
I wanted to know about the aluminum heatsink. Does the SCR have a heatsink that isolates it from the aluminum?
I'm attaching a photo of the board.

There is no way to try it, without going to connect it, just card? Simulate only the engine output, adjust the pwm? And if there is an electrical diagram that can be executed on the board. Thank you

On the bench, the MC2100 board requires a 20Hz PWM into pin 4 of HD2.
There are a few circuits out there, and also a very cheap PMW controller with digital display sold on line.
I also made up some small ones using a pic micro.
