Single Axis Stepper Drive
Power and customized flexibility in a small modular design
Several levels of cirucuit protection eliminate repairs or costly field replacements
Operates with widely used off-the shelf software packages such as Mach3 by Artsoft
Connects to industry standard computer or PLC ports for easy control
Benefits:
- Add processor boards to design a complete custom machine
- Use up to 2.5A per phase of bipolar stepper motors: two motors per board
- Adjust current control with on-board potentiometer, then fine tune to match the current requirements of the motor being used
Key Features:
- Single power supply; recommended 12 or 24Vdc input power.
- Jumper selectable microstepping; selectable in full, half, 1/4, 1/8th (1/16th step available as custom option).
- High speed optically isolated inputs
- I/O control of devices such as limit switches and relays
- Diode and fuse protected electronics can save replacing the drive board in the field
- Isolated voltage regulation for each axis giving high noise immunity
