Servo drives made by Dynamic Motion Motor Technology Corporation. They are meant to work with their servos which have absolute serial encoders, however it seems they can be adapted to work with any quadrature/incremental encoder servos.

They support digital position mode control over discrete inputs or RS-232/modbus, as well as velocity mode with an analog input. This makes them easy to integrate with any controller.
