Physical Characteristics and Installation
This servo drive weighs approximately 4.80 kg for secure cabinet mounting. Its dimensions measure 380 mm x 220 mm x 180 mm for robot controller racks. First, slide the 3HAB8101-1/03B into a dedicated drive slot. Then, connect the 3-phase AC input power to the terminal block. Finally, wire the motor feedback and power cables to the front connectors. LED indicators show drive status, fault conditions, and communication activity.
Power Specifications and Motor Control
The 3HAB8101-1/03B accepts 400V to 480V AC three-phase input power. This drive delivers 15 A continuous current for normal robot operation. Peak current reaches 30 A during acceleration and heavy loads. The output frequency ranges from 0 to 400 Hz for wide speed control. Three control modes provide flexible operation. Position mode follows programmed trajectories precisely. Velocity mode maintains constant speed. Torque mode controls applied force.
Feedback and Communication Interfaces
This servo drive accepts resolver or encoder feedback from the motor. A resolver provides rugged position sensing for harsh environments. An encoder offers higher resolution for precision tasks. The 3HAB8101-1/03B uses SERCOS or DeviceNet for real-time command exchange. Consequently, the drive synchronizes perfectly with the main robot controller. The IP20 rating suits installation inside protected electrical cabinets.
