maxon motor EPOS4 24/1 motion controller for DC motors

Available on request is the EPOS4 24/1.5 DC motor control module. Weighing just 17 g and measuring 39 x 54 mm, the position controller can also control both brushed DC motors and brushless DC motors (BLDC motors).

The product retains the full motion control capabilities of larger controllers, including RS232, USB, CanOpen and EtherCAT communications onboard or via adaptor modules. Feedback from the DC or BLDC motor is achieved using either hall sensors, incremental encoders or absolute encoders. It can be used with current/torque control, closed-loop speed control and position control.

Designed primarily for use on 12 or 24 V systems, the controller is based on a high PWM frequency of 100 kHz for adaption with highly dynamic ironless and coreless DC motors that have low inductance levels. Current limiting, overcurrent, overtemperature, undervoltage, overvoltage and short circuit protective functions are all included.

Free set-up software for auto configuration and tuning of motors is supplied, along with programming examples for PC, PLC, LabView and Linux environments. IEC61800-5-2 based Safe Torque Off (STO) makes the controller suitable for use in critical applications such as manufacturing processes and collaborative robotics.
