OVERVIEW

This card lets you control your spindle with step and direction signals as if it were an axis motor. It converts the step signal to an analog (0-10VDC) and by using the onboard relays, you can control the direction (CW/CCW) and enable the drive (On/Off). A Variable Frequency Drive or Inverter works by modifying the frequency for AC motors. You can control most of these devices with an external analog signal (0-10VDC). That is, if 5VDC is coming in through the control signal, the motor will run at 50% of full speed; if there was 10VDC, the motor will run at 100% of full speed. If there is no signal coming out, then the motor will stop. This unit can also be used on many DC motor controllers by replacing the potentiometer that controls the speed.

FEATURES

  • Inputs a frequency (step) and outputs an analog 0-10VDC.
  • Have two relays that can be used to control the direction and enable and disable the drive.
  • Opto-isolated output signals. The analog and CW, and CCW signals are optically isolated, so this board can be used with drives that make grounds common with the mains that drive the VFD or motor.
  • All TTL +5VDC or +3.3VDC Signals. Interfaces directly with parallel port interface products and other cnc4pc.com cards. 5VDC (TTL) signals are very common among automation devices.
  • Flexible design. It works with cnc4pc’s products directly through your parallel port or through many other parallel port control products.
  • RJ45 Connector. This connector is for connecting the boards directly using a standard RJ45 cable, allowing it can be used to carry input signals and power lines.
