A Multi Axis Motor Control EPOS2 36/2 Motherboard

Operating as standalone controller or integrated into final product as sub-board, EPOS2 36/2 Motherboard features snap-apart construction with 11 nodes connected via CAN-Open, allowing multi-axis customization on single board. Two digital inputs and 1 digital output are mapped on board with additional I/O expansion module as option. In addition to motor speed, torque, and position control, EPOS2 36/2 is capable of synchronously running coordinated multi-axis path dictated by interpolating points.

Intelligent control applications often call for multi-axis solutions to meet demanding performance requirements. Configuring a control solution in a mother board / daughter board array is a convenient and proven method of addressing these types of applications. OEM style daughter boards, like Maxon's EPOS2 36/2 drive/controller, offer excellent flexibility in design but require custom wiring solutions. This process is often too expensive and time consuming for designers who may not have the resources to undertake a complete development, especially with increasingly short proof-of-concept times. The new EPOS2 36/2 motherboards make product development faster and easier, giving the designer either a standalone multi-axis motor controller or one that can be integrated into the final product as a sub board.


Starting with 11 nodes connected together via CAN-Open, the unique snap apart construction allows for quick multi-axis customization on a "single" board. Each node mates with an individual EPOS2 36/2 drive/controller and provides connection points. Standard cables are available in stock. Two digital inputs and one digital output are mapped on the board with an additional I/O expansion module as an option. USB and RS232 communication modules are available for users that don't want to use CAN.

Functionalities of the EPOS 2 motor speed, torque and position controller with multi axis motherboard include:
• Speed and Position feed forward control. EPOS supported motion controlled acceleration and speed.
• PVT - Interpolated Position Mode. The controller is capable of synchronously running a coordinated multi-axis path dictated by interpolating points.
• Step and Direction. Implemented for replacing stepper motors with highly dynamic brushless DC motors.
• Point to Point motor position control. The CANopen Profile Position Mode moves the position of the motor from point A to point B. The motor position is relative to the absolute home position or the axis relative position.
• Torque Control. Sinusoidal motor control resulting in a minimum torque ripple.
• Electronic Gearing. Using an external encoder as a master, multiple motors can be synchronized with a user input software gearing factor.
• Motor Holding Brake Control.
• Position Compare and Position Mark. Save and sending of digital signal (Trigger and Capture)
• Dual Loop Speed and Position Control. Precision motor control with load mounted high resolution SSI absolute and incremental encoders.

Servo2Go - Low-cost Tin-Can Stepper Motors from Nippon Pulse feature high torque and compact size

The PF/PFC series tin-can stepping motors are conventional magnet-driven rotary stepper motors with a permanent magnet in their rotor core. Rotating in proportion to the number of pulses sent to the motor, the stepper motor is frequency synchronized and can change speed depending on the frequency of the pulse signal.
