Re: VICTOR RESPONSE DELAY? - AGAIN

To add some explanation...
The output frequency of the Victor was reduced in this model vs the previous model. With the type of motors we use, the 120 Hz rate works better when considering the brush design and rep rate of brush and commutator. This allows better average current control for the motors.
From IFI FAQ for Victors...:The Victor will turn ‘On’ at a value of 138 and it will be at Full Forward condition at a value of 232, which is 94 steps. The output will vary linearly from 3% to 100% over these 94 steps." This compensates for the poor performance of the pots in standard joysticks.
