Product Description:

The CSB02.1A-ET-EC-CN-L3-NN-NN-AW drive controller is manufactured by Bosch Rexroth Indramat within the CSB Drive Controllers series. Installed inside a control cabinet, it governs one motor axis by converting network commands into precisely metered phase currents. Integrated feedback processing and safety logic let the device coordinate positioning, speed, and torque loops for conveyors, pick-and-place stations, and automated assembly cells, reducing the need for separate interface modules. Its cabinet-mounted design keeps command handling, feedback evaluation, and safety response in one unit for compact machine layouts.

Internally, the hardware supports a single-axis configuration and is supervised through seven digital inputs, one configurable digital I/O channel, and one analog voltage input. The input set supports trigger capture and basic field wiring for auxiliary machine signals. Two probe inputs capture edge-aligned position events, while a multi-encoder interface supplies 5 V at 500 mA with an overall encoder power budget of 6 W. Field communication to decentralized I/O racks can be handled over a CANopen bus that uses a 9-pin D-Sub connector. For real-time motion commands, the controller exposes an Ethernet node on an 8-pin RJ-45 port that follows the IEEE 802.3u Fast Ethernet standard. The Safe Torque Off function removes gate drive energy when an emergency stop is asserted and disables motor power without relying on mechanical contactors.

Signal integrity for the encoder channels is maintained by an EC-sine bandwidth of 400 kHz and an EC square-wave capability of up to 1000 kHz, allowing high-resolution feedback devices to operate without aliasing. These measurement limits complement the controller’s Multi-Ethernet stack and allow synchronized motion data, CANopen diagnostics, and encoder feedback to be exchanged at the same time without overruns. The controller can process feedback signals and network traffic in parallel during closed-loop operation. This arrangement also supports stable communication behavior when the axis is handling positioning, speed regulation, and event-based sensor updates at the same time.
