MAXON Motor has released a digital positioning controller for brush and brushless DC motors.
The EPOS2 provides control for the motors via an encoder, and is said to be suitable for applications where decentralised drive intelligence is needed. It is modular and based on the CANopen standard, and can handle a performance range from one to 700 watts.
According to the company, the controller operates in position, speed and current control mode, and can be programmed via the software to operate with both DC and EC motors. This allows the unit to be used in drive systems in a variety of operations such as automation and mechatronics.
The EPOS2 has 32-bit digital signal processing technology, allowing it to carry out complex mathematical algorithms. It is said to have protection against electromagnetic interference, and has an interpolated position mode to synchronously run a path specified through interpolation points dynamically.
The company claims the controller can carry out coordinated multi-axis movements and any profile on a one-axis system if it is connected to a suitable master.
Online commands can be programmed using CAN Master, or via USB and RS232 interfaces through a PC.
The controller is said to have a compact design, allowing it to be used in areas such as as tool building, production machinery, and automation tasks.
