Product Description:

Bosch provides the trusted KDA 3.1-050-3-API-W1 Spindle Drive for applications that requires accuracy and precision. It is built for industrial motors with high current demands. The spindle drive provides steady control of motion in complex automation environments.

The KDA 3.1-050-3-API-W1 drive works on a 300 V DC bus voltage. It has a rated current capacity of 50 A. This supports stable high-power output in continuous machine operation. The command signal type aligns with speed control mechanisms. It accepts an analogue signal format for precise input handling. The external communication signals connect through the X2 interface. This input supports ±10 V analogue and digital signal types. It is compatible with PLC or CNC controllers. The spindle drive has a series type marked as 3 for model classification. Its internal design is categorized under type 1. It has X4 and X5 connectors to support motor feedback. These are D-sub ports for resolver or encoder signal input. The connectors use 15-pin or 17-pin DSUB format. This makes sure it is conformed with standard feedback devices. The signal format allows accurate control of motor rotation speed. The design of the spindle drive is built such that it fits easily into standard control cabinet layouts.

The KDA 3.1-050-3-API-W1 drive ensures accurate response to analogue speed control signals. The Bosch spindle drive supports stable DC input. It allows safe and easy integration with controller-based environments through the X2 interface. This attribute ensures reliable operation in challenging industrial settings. The KDA module assures fast control loop response in speed-driven setups. The analogue control input of the drive helps to minimize communication delay. The spindle drive provides continuous current regulation when the load is changing.
