Product Description:

The CSB01.1C-S3-ENS-MA1-L1-S-NN-FW control section belongs to the CSB Drive Controllers series produced by Bosch Rexroth Indramat. Installed in modular Rexroth inverters, the card manages axis signals, provides analog and fieldbus interfaces, and ensures coordinated motion control inside industrial machinery such as packaging stations or material-handling gantries. By combining sensor feedback, drive commands, and safety interlocks on one board, the unit serves as the local intelligence that links a servo motor to higher-level automation assets. This arrangement lets the inverter handle motion commands, feedback processing, and machine coordination within the same control layer during normal operation.

Two differential analog input channels accept command voltages within a range of ±10 V, and their conversion accuracy is held to ±0.3%; this tolerance affects how closely the controller reproduces reference values from a PLC. The 1 MΩ input resistance prevents loading of upstream electronics. Analog outputs share the same ±10 V span and can supply reference signals for velocity or torque loops. Master communication occurs through Sercos III, while the Ethernet PHY supports the 100Base-TX standard so telegrams travel at wire speed between the drive and controller. For incremental feedback, the TTL interface can count edges up to 400 kHz, allowing precise position capture at high spindle speeds.

Two analog output channels share a common DAC and, when loaded with 1 kΩ or more, can issue stable speed or current references without clipping. Encoder power is supplied at 11.6 VDC with a maximum current of 500 mA, enabling direct connection of optical or magnetic encoders through the female D-Sub-15 socket. Remote diagnostics enter the board through the shielded RJ-45 8-Pin port that also carries drive data packets. The service connection supports remote status access without disturbing the main feedback path or the command path during operation. For machine safety, a start command is ignored until the external lockout contributes 24 V / 3 mA; this small pilot load lets simple relay contacts satisfy the interlock requirement.
