Hi!!! I just finished a Gecko drive and homeshop 1200 oz/in retrofit. I used a 70 volts 1500 watts power supply from Antek.inc At slow speed all works fine, but when I increase it motors stop. If I check voltaje on capacitor, it goes down (has 2 paralel conected 50000 mF, 80 volts). If I stop movement just 2 or 3 seconds and started again, all works fine about 5 minutes. My solution was increase size of capacitor. Buy a 54000 mF capacitor and use it in parallel with the other and after 1 second of noise bridge blows!, I buy a biger bridge, same conection and blows too. Is this a resistor problem?? or to small bridge? or to big capacitor? or is another problem? help!
