Servo Excels at Direct Drive

The Dynaserv G3 digital servodrive comes in a compact package and incorporates advanced control and filtering algorithms.


It is particularly suited to direct-drive applications and will operate in torque, velocity, or position mode when using a motion controller, or take advantage of motion-table functions to incorporate into a PLC system. The motion tables essentially make the drive a single-axis controller, allowing the storage of indexing moves that can be initiated through a serial command or commanded via discrete inputs. There are 12 onboard inputs and six outputs. Windows-based software simplifies setup and an autotuning tool is available when operating in position-control mode. An oscilloscope function is included for advanced tuning with improved low-pass and notch filters. The drive also has additional safety features such as a controlled stop after power failure and a servo disable switch on the front panel. Included as well is special circuitry to monitor power regeneration to the drive.
