It measures 241 mm in height, 103 mm in width, and 49.5 mm in depth, and is equipped with a standard control panel, two encoder interfaces, and an RS232 serial interface supporting speeds up to 115 kBaud.
Internal Product Review
The CSB01.1C-S3-ENS-ENS-NN-S-NN-FW is a Bosch Rexroth Indramat drive controller engineered for single-axis applications with SERCOS III communication. Dual IndraDyn/HIPERFACE/1 Vss/TTL encoder interfaces and a 125 µs current control cycle support accurate feedback processing and very responsive regulation. An 8 kHz maximum switching frequency makes this unit a strong performer in demanding servo systems.

Product Description:
The CSB01.1C-S3-ENS-ENS-NN-S-NN-FW control section is manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. Installed in a larger servo inverter, it handles the real-time regulation tasks needed to run a motor axis, translating fieldbus commands into precise current and position signals. By integrating communication, encoder handling, and basic I/O on one compact card, it serves as the interface between a higher-level PLC and the power electronics that drive industrial machinery.
It drives a single mechanical axis, so the internal motion processor is dedicated to 1 coordinated motion channel. Communication with the automation bus is handled through SERCOS III, allowing synchronous telegram exchange with jitter in the sub-microsecond range. The current regulation loop updates every 125 µs, which determines how quickly torque commands can react to load changes. For position verification, the board provides 2 × IndraDyn/HIPERFACE/1 Vss/TTL encoder interfaces, enabling either high-resolution absolute or incremental feedback. Power transistor gating is modulated up to 8 kHz, a switching limit that shapes motor current with reduced audible noise and manageable thermal dissipation.
The front panel exposes 3 combined digital and analog inputs and outputs that can be assigned to drive enable, fault reset, or process-related signals. Two dedicated capture channels accept external marker pulses; these 2 probe inputs timestamp machine events directly inside the drive. A safety relay is not installed, but one general-purpose contact rated as 1 N/O is available for field interlock tasks. Parameter access over the auxiliary service port follows the RS-232 physical layer and supports data exchange up to 115 kBaud, so diagnostics and trace functions can be performed without occupying the real-time bus. The standard control panel clips onto the housing, and with dimensions of 241 mm height, 103 mm width, and 49.5 mm depth, the section fits inside compact electrical enclosures where airflow is limited.
