The Dynaserv is a family of direct-drive servo systems for industrial and high-tech applications. Direct-drive systems are integrated positioning systems that allow the elimination of mechanical transmissions and allow the load to be mounted directly to the motor. This creates an extremely highperformance system that can simplify and increase the performance of many machine types. The Dynaserv G3 is the latest generation drive of the Dynaserv family and provides optimal control of a direct-drive system.

The G3 is an all-new digital drive with implementation of the advanced control and filtering algorithms needed to control a direct-drive motor. The G3 can operate in torque, velocity, or position control modes. The G3 comes with a modern Windows-based software utility that makes the set-up of the Dynaserv system easy and fast via RS232 or RS485 communication. When operated in position mode, the Dynaserv has an auto-tune utility that allows quick and easy setting of the tuning parameters. Digital implementation of the low pass and notch filtering makes mechanical resonance abatement far easier than in earlier models.

Simple motion control functions can be obtained without an external controller. The G3 contains a motion table that allows the storage of indexing moves that can be initiated through a serial command or commanded via discrete inputs. When used with a PLC using multiple inputs, the G3 can be used to achieve high-performance motion and handle complex tasks.

The Dynaserv is UL recognized and meets the requirements for CE certification. The G3 has additional innovative safety features such as a controlled stop after power failure and a servo disable switch on the front panel of the drive. Since the Dynaserv motor is capable of handling very large loads, the G3 has special circuitry to monitor power regeneration to the drive.

The G3 is a very flexible design allowing operation of the all the DM series motor models and the standard DR series motors. The G3 is also compatible with the Linearserv linear motor system.
