With its superior motion control algorithm developed to meet the most demanding accuracy requirements the Mclennan Digiloop PM600 motion controller enables unparalleled motor control and accuracy to be obtained. Its low unit cost facilitates economic control unlike any other motion controller. This single axis controller is able to achieve much tighter loop control resulting in zero error. This, combined with the Digiloop algorithm results in superior smoothness, stability and positional accuracy, even when remotely mounted high resolution encoding is employed. Where the sequential control of two axes is required however, a single Digiloop PM600 may be used to control two motors. Its compact size ensures that even where the control of multi-axis systems is required the Digiloop PM600 remains a space efficient and economic solution. In such systems the required number of controllers are simply linked together via RS232 or RS485 thereby providing the ultimate flexibility and maximum up-grade potential.
