SD6 Servo Drives with Quick DC-Link System

Energy Utilization Options via DC-Link Connection

All SD6 drive controller series offer the option of connecting to a DC link. This technology enables regenerative energy produced by one servo drive to be used as motor energy by another servo drive. Regenerative energy is generated when the load drives the motor, thereby feeding energy back into the drive controller. If motor and generator operating states change frequently or regularly, the resulting excess energy can be transferred to one or more additional drive controllers. This is achieved via the DC intermediate circuit connection.

Quick DC-Link

The DL6 Quick DC-Link module was developed to provide a reliable and efficient rail connection to the DC intermediate circuit. Connection between SD6 drive controllers is established using standard busbars (e.g., 5 mm x 12 mm). The rail mounting is tool-free, using quick-clamp terminals for easy installation.

Reliable and Safe Thanks to Motion Control

Typical applications can be found in winding technology, stacker crane systems, conveyor and handling technology, or systems with gravity-loaded axes. Another practical use case for the DC-link connection is in setups with multiple inverters using braking resistors. To make the best use of regenerative energy, it is essential to coordinate and control the drive sequences and motion profiles.
