Hi,
I am using several 0808THS cards and on one of them I have both blocks 1 & 2 set to PWM. So output O0, O1, O4 and O5 are normal PWM outputs.
O1 & O2 are working great, f = 3 kHz Duty Cycle at 50 the control is very smooth.
On O4 & O5 with the same settings the motors are spasmodic in starting and stopping. (I mean too fast motor operation).
Why on the first set of outputs the Duty Cycle at 50 is so smooth (slow motor speed) and on the second set the same Duty Cycle does not work out the same?
Anyone faced a similar problem?
thanks
