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.
