The Pico Systems Analog Spindle Speed DAC is an add-on module for both the Universal Stepper Controller and the Universal PWM Controller to generate +/- 10 V analog speed commands for a spindle drive that is controlled by an analog voltage. It can be software configured for drives that need a positive voltage to control speeds in either direction, which is selected by a contact closure provided by the controller, or a drive that requires the sign of the voltage to change to select the direction. This unit can also control any device which requires less than 10 V. The voltage to RPM scaling is set in the CNC software. It could also be used for any other function that requires a relatively coarse analog voltage that does not need to vary quickly. A laser power control might be another example. |
