OFDL - Open Frame Drive

OFDL - Open Frame Drive

The OFDL presents a new level of servo drive cost-benefit ratio. It is an integrated digital servo drive designed to provide the benefits of a full-featured drive while at the same time being low-cost. The OFDL consists of a single circuit board including both the power stage and the digital circuitry. Input and Output circuitry enables the OFDL to be used for machine control functions in addition to the servo drive capability. The drive software has been designed such that additional communications capabilities such as CAN bus or ModBus can be easily added in order to meet the needs of specific applications.

 

Key Benefits

·         Open-frame reduces cost while allowing for direct mounting within an enclosure.

·         Modular software architecture designed to enable simple implementation of new features.

·         Additional Hardware features can be added using high-density pin header connector

·         Complete servo drive functionality in a low-cost package
