400V

Three-phase

Design Features

1. Improved Performance

z Higher bandwidth response (up to 400Hz speed loop frequency response)
z Positioning settling time shortened to 1/2 to 1/3
z Smooth control at low rpm

made possible by Sigma II servomotors’ high resolution feedback

2. Easy Operation

z All-in-one model (speed, torque, and position control)
z PC monitoring function available including graphical tuning and file storage
z Adaptive-tuning function

Online auto-tuning

z Multi-axis communication provided as standard

One PC can communicate with up to 14 SGDH units by parameter setting

z Built-in parameter setting device
z On-board storage of alarm history
z Automatic determination of motor settings at connection

3. Additional functionality with ready-to-install application modules

z Configurable single axis controls including serial communication capability
z Fieldbus connectivity (Devicenet¥, Profibus¥, etc.)
z Full closed loop (optional position feedback)
z Single axis motion controller

4. Certified International Standards

z UL, cUL listed (File #: E147823), CE compliance
