Product Description:

The CSB02.1B-ET-EC-EC-NN-DA-NN-AW drive controller is produced by Bosch Rexroth Indramat for the CSB Drive Controllers series. Designed for servo and spindle duties, the unit integrates motion logic, feedback processing, and network interfaces so a single cabinet module can command automation axes in packaging lines, handling gantries, or machine tools. It accepts encoder signals, manages power to the connected inverter stage, and forwards status data over industrial Ethernet, providing deterministic control of motor position and torque.

This controller operates from a 24 VDC control supply and draws a base load of 17 W, keeping standby heat low inside the panel. Command data and diagnostics travel through the integrated 100Base-TX port, and the backplane also supports Multi-Ethernet protocols for mixed real-time networks. The voltage input channel offers a bandwidth of 1.3 kHz, an input resistance of 300 kΩ, and a resolution of 14 bit, so finely scaled reference signals can be interpreted without external conditioning. Digital or analog I/O extension modules can be added, and encoder feedback is accepted on two independent multi-encoder ports. The controller does not include integrated safety technology, so external relays must interrupt the drive enable circuit when risk conditions are detected.

The single-axis capacity is rated at 1, matching machines that dedicate one controller per mechanical axis. Position feedback can be sourced from 12 V or 5 V encoders; each supply rail can deliver 500 mA, and the same current is available on the programmable digital outputs for solenoid or relay actuation. When analog process data must be retransmitted to higher-level PLCs, the output settles within 250 µs, supporting tight closed-loop cycles. Network interchange supports Multi-Ethernet, allowing selection between EtherNet/IP, PROFINET, or EtherCAT without hardware changes. Encoder current monitoring, voltage-input resolution, and a base power meter support diagnostic visibility during operation.
