Product Description:

The CSB01.1C-ET-ENS-NNN-NN-S-NN-FW is a compact drive controller section manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. It forms the control core of a motor inverter, taking setpoint data, monitoring feedback, and issuing gate commands so a single servo axis can be synchronized with the wider machine sequence in automated packaging, material handling, or machining lines. Serial servicing is handled through the RS232 port, giving direct access for diagnostics and parameter access when a network connection is not used.

Its hardware layout is tailored for single-axis operation, meaning one power section is directed by this control section. Network traffic is carried through the Multi-Ethernet interface, so the unit can join EtherNet/IP, PROFINET, or EtherCAT topologies without extra cards. Integrated digital I/O channels and an onboard relay output let the controller accept limit switch signals and control external contactors locally. Feedback ports support the IndraDyn and Hiperface encoder protocols. They process differential analog and digital signal levels of 1 Vpp and 5 V TTL respectively, allowing the controller to read high-resolution sine-cosine signals or discrete marker pulses. When additional conditioning is needed, one expansion slot accepts encoder extension, analog I/O, or emulation modules, while the base model is supplied without an optional module.

A single expansion slot is accompanied by a MultiMediaCard socket for parameters and machine data. Daily operation is handled through the standard operator panel. Configuration is handled with IndraWorks, which provides parameter editors and oscilloscope tools over Ethernet or the serial connection. The controller's integrated digital I/O and expansion capability keep the footprint small while still supporting encoder emulation or analog scaling when an auxiliary card is installed.

Fault Code Diagnostic Text (display) Typical Cause(s) Quick Troubleshooting Steps
F2026 Low DC-bus voltage Mains dropped; supply or regen unit overloaded Restore mains, check supply/regen sizing, clear error after voltage stabilises 
F2028 Excessive deviation Load jam, poor tuning, encoder slip Inspect mechanics, retune position loop, enlarge monitoring window (S-0-0159), reset diagnostics
F8022 Encoder 1 signals incorrect Damaged/loose cable, noise, grounding issue Reseat or replace cable, verify shielding/ground, reroute away from power lines
F8025 Over-voltage in power section Regeneration energy, faulty brake resistor, mains spikes Check DC-bus, test brake resistor, add regen unit or adjust decel ramps
F8070 +24 V DC error Control-logic supply out of range, loose X31/X32 connector Measure 24 V rail, repair connector or PSU, verify 18 – 30 V window
F8057 Device overload shutdown Thermal overload of IGBT / heatsink Improve cabinet cooling, clean filters, let drive cool, reduce duty cycle
F4002 MDT lost (bus telegram) Fiber-optic/bus dropout, wrong timing Clean/replace FO cables, check master timing, restart comms phase
F2816 Soft-start DC-bus trajectory error Pre-charge or contactor sequencing fault Inspect pre-charge resistors & contactor, verify sequencing logic
F2174 Motor-encoder reference missing Absolute encoder not homed after power-cycle Perform reference move, store position reference, reset diagnostics
F9002 Internal RTOS function-call error Firmware corruption or control-section fault Power-cycle; if persistent, update firmware or replace control section
