Complex interpolated position requirements across a diverse range of small DC servo motor and brushless servo motor applications often requires the design of custom motherboards to use the already available range of OEM style motion control daughter boards. However this process is often too expensive and time consuming for designers who may not have the resources to undertake a complete development. The new EPOS 2 36/2 motherboard range makes product development faster and easier, giving the designer either a stand alone multi axis motor controller or it can also be integrated into a final product development as a sub board.
It can be supplied from 1 through to 7 axis in a single piece or coupled together via a CAN jumper to extend the motion control system out to 127 nodes. The CAN address has an onboard dip switch option to support the software settings. It features a unique snap apart construction that aids production by loading all the boards on the sheet and allowing the separated parts to be re-used. There are also sub modules available for USB connection and CAN termination to assist with production efficiency. There are two size variants that allow for either x2 digital inputs or the full configuration of the EPOS 36/2 digital and analogue inputs and outputs. Standard connector types are used to suit the maxon EC-max brushless DC motor range and the maxon EC-i 40 pancake brushless DC motor range.
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.
Sinusoidal motor control resulting in a minimum torque ripple.
Mechanical reference points set via 30 possible calculation methods.
Independent and I /O resultant velocity control.
Using an external encoder as a master, multiple motors can be synchronised 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)
Stand alone capability via external analogue set values.
Dual Loop Speed and Position Control.
Precision motor control with load mounted high resolution SSI absolute and incremental encoders.
