Thats exactly why I use the high wattage resistors to drain HV from the DC motor supply. Its not instant takes about 0.5s or so. Without it the Geckos hold power for a surprising length of time. Many people do this by putting a drain resistor across supply capacitor, but I think this is inefficient as its always in the circuit and can act as a workshop heater if things go pear shaped! Much better to switch it in as part of the estop circuit (in my opinion). |
