Help! PWM 0-10V.

[AlieLeite]

Hello...i think If using the parallel port you don't need to set a speed or acceleration in the spindle axis tuning tab. If you are using a Smooth Stepper, you Do need to set up an acceleration value.
Controlling a spindle via a 0-10V signal is an Open Loop control. Putting aside Mach3 closed loop function that has some problems, there is no feedback loop to to ensure that the speed you are asking for is actually being obtained by the motor. The
The control voltage is generated as a ratio of the speed set by the S over the maximum speed set for the Mach3 pulley being used.

I need to use to alter the axle speed JP6 IO26 Gen Reason PWM0 out I need to use to kill the axle on and. JP6 IO27Gen Reason LVTTL I/O 3.3V Determination of the converter: input3.3V Level0-100% PWM Flag, output0-10V Voltage PWM Flag getting recurrence range: suggested 1KHZ-3KHZ

The goals of this module are 0.1V

1, DIN+: PWM flag input is. (basic cathode strategy. Here the PWM flag, an all-out association)

2, Clamor: PWM flag input. (regular cathode technique. Here the flag terminal GND, anode association, PWM motion) here.

3, 12-30V: control input positive end.

4, GND: control ground.

5, GND: Flag ground. The GND port is associated with the power supply ground wire.

6AO: Analog voltage0-10V Yield port.

Hi smrutibora,

I can't understand your question.

You might start with the PWM1KHz.c example to test your hardware.
