Product Description:

The CSB01.1C-NN-ENS-NNN-NN-S-NN-FW is a drive controller unit produced by Bosch Rexroth Indramat within the CSB Drive Controllers series. As a single-axis control module, it is installed in IndraDrive power sections to execute current, velocity, and position loops for one motor channel in automated machinery. Its role in industrial automation is to coordinate motion while providing local I/O handling and feedback processing so that higher-level PLCs can offload time-critical drive tasks. This arrangement lets the control unit and power section operate together as a compact axis controller inside a larger machine system.

This unit manages 1 axis and integrates 3 combined digital I/O channels that can be parameterized for status or command signals. The current control algorithm updates every 125 µs, giving the drive the timing precision needed for stable servo response under changing loads. Field devices connected to the controller operate at a logic level of 24 V, which matches common sensor and actuator supply rails in control cabinets. Feedback from motors or external encoders is accepted through the IndraDyn / Hiperface / 1 Vss / TTL interface, so the unit can work with sine-wave, incremental, or absolute encoder signals. This broad feedback compatibility supports use with different motor and encoder combinations without requiring additional interface hardware.

For setup or diagnostics, an onboard serial link uses RS232 and communicates with compatible service tools. One form-C relay rated as 1 N/O is included for ready-to-operate signaling or simple interlocks, and a standard control panel is fitted on the front plate for local parameter entry. The safety backplane provides a slot for safety configuration, but this model is supplied without a safety option, so any safety functions must be added through an external module. Dedicated type B and type C probe inputs each support a trigger channel for position capture during motion testing, which is useful when monitoring timing-related motion events.
