Stepper Motor Controllers

The OLTOM PWM stepper motor cards contain both driver and control logic and are very easy to program. An additional advantage is that the cards are software compatible: The same control programs can be used for any card model with little or no change.

Several cards can be linked together and controlled from one host computer (using a single RS232 port). The cards can also be directly controlled from the built-in I2C bus. This allows extremely compact applications. For more information on how to best use I2C, please contact us.

Both rack mount and corner hole mounting with screw terminal connectors are available.

Common Features

• Link several cards or boxes with the built in I2C-bus.
• Synchronize commands and movement between different motors on different cards with high precision.
• Only 0.3 millisecond synchronization delay between command execution in the worst case scenario.

Boxed PWM3 Dual Axis Stepper Motor Card

The boxed version of PWM3 is an advanced stepper motor controller and driver card in an attractive enclosure.

Just place the box on your bench, connect two motors, a DC power supply, a computer, and the motors are to ready to run.

• Control two motors with one box
• RS232C-compatible serial port for control. USB-adapter available on request.
• SMCP LE Windows program bundle.
