Servo System Line

Manufacturing Engineering, Mar 2007

Designated the XtraDrive Servo System line by the manufacturer, YET US (Manchester, NH), these controls feature an integrated amplifier and a 5-kW, 1.5-axis controller with ECAM capability to provide complex motion profiles based on master or virtual-axis encoder position. The 400 Vac, three-phase input drive system achieves speeds to 6000 rpm with torque range to 629 lb-in (71 N*m). Operation delivers 16.5-A rms continuous and 40.5-A rms peak.

Functioning as a stand-alone unit, the servo system integrates into new or existing motion systems, or can be driven by an analog or step-and-direction reference from a PLC or multiaxis controller. Units are configured with two analog inputs, two analog outputs, seven programmable digital inputs and three programmable (four dedicated) digital outputs. Support options include extended I/O, Devicenet, SERCOS, and MACRO. Embedded Profibus DP platforms are also offered.

Based on patented NCT (nonlinear control) servo control technology, the equipment reportedly solves system flexibility, tuning, and compatibility problems. The adaptive control structure provides stability and eliminates costly retuning efforts by automatically adjusting to changing load requirements. Configured for compatibility with all brushless rotary and linear servomotor technologies, the unit can support various feedback devices including A quad B encoders, serial encoders, sine-cosine encoders and resolvers.
