Compact Motion Controller

The EPOS 24/5 is a digital motion controller capable of position, velocity, and current-mode operation.

It features a small package size of 105 x 83 x 24 mm (4.2 x 3.3 x 0.9 in.) and weighs 170 gm (6 oz). Communication is via RS-232 or CANopen software and Windows DLL. The controller works with brush and brushless motors and requires a supply voltage of 11 to 24 Vdc. It is capable of 5-A max continuous current and 10-A peak current. Efficiency is up to 90%. The 50-kHz switching frequency and built-in choke ensures compatibility with most low-inductance motors, while the sinusoidal commutation for brushless motors ensures minimal torque ripple and low noise. Maximum motor speed is 25,000 rpm for two-pole motors. A maximum encoder input frequency of 1 MHz, six digital inputs, four digital outputs, and two analog inputs allows for maximum flexibility.
