Product Description:

The CSB01.1C-NN-ENS-MEM-L2-S-NN-FW is a controller card manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. Intended for multi-axis drive systems, the board manages current regulation and encoder feedback so servo motors follow commanded motion profiles in automated production equipment. It is delivered without an onboard fieldbus communication option, making it suitable for installations where axis coordination is handled through other controller levels.

Its control performance stems from a cycle time of 125 µs, meaning current is recalculated eight thousand times per second for tight torque regulation. The module’s physical envelope of 241 × 49.5 × 103 mm permits dense panel layouts while maintaining access to front connectors. Internal PWM logic supports a maximum switching frequency of 8 kHz, a rate that balances dynamic response with thermal loading in the connected power stage. A certified safety circuit implements Safe Torque Off (SIL3/Cat. 3 PL e), allowing drive energy to be removed through redundant hardware paths. Parameter tuning and service diagnostics use the integrated RS232 serial port, and no additional fieldbus resources are present. Absolute and incremental encoder signals can be emulated for systems that need standardized feedback formats.

The encoder channels are routed through a dedicated ENS socket that supplies 12 V to a D-Sub 15-pin female connector, keeping sensor power independent from drive logic. Position data can also be exchanged over the L2 diagnostic link; its acknowledgment line is rated for 24 V / 1 A, while the main L2 interface uses a 9-pin plug that sinks only 3 mA at 24 V. A MEM connector, also 15-pin, supports cable runs up to 40 m and delivers captured encoder edges at up to 1 MHz; edge skew is limited to 50 ns, with SSI timing that uses a 20 µs clock break and 650 ns delay. Compatibility spans IndraDyn S, HIPERFACE, EnDat 2.1, 1 Vpp transducers, giving the controller flexibility for mixed-sensor installations.
