Product Description:

The Bosch Rexroth CSB01.1C-S3-ENS-EN2-NN-S-NN-FW is a servo drive controller from the IndraDrive system. Belonging to the CSB01 series, it is designed for precision motion control in industrial automation. With key features such as Sercos

Ethernet communication and external encoder support, this drive offers high-speed communication and enhanced motion-tracking capabilities. Bosch Rexroth is a global leader in automation technology that provides reliable solutions for demanding automation tasks.

The CSB01.1C-S3-ENS-EN2-NN-S-NN-FW servo drive controller utilizes Sercos

Ethernet for fast, real-time communication between the drive and controller. This ensures efficient data transfer in complex automation systems. The ENS marking indicates the drive's capability to control servo motors, which are essential for tasks requiring precise motion control and high efficiency. The external encoder support (EN2) allows for independent motion tracking in addition to the motor's primary feedback. It improves system performance in applications requiring fine-tuned control. Designed for medium-power systems, this drive is suitable for CNC machinery, robotics, and other automation setups. Integrated firmware support (NN-S-NN-FW) offers the flexibility to upgrade the drive's software to meet specific operational requirements. This makes it highly adaptable to changing system needs.

The CSB01.1C-S3-ENS-EN2-NN-S-NN-FW servo drive controller incorporates advanced safety features that align with modern safety standards that provide reliable protection during operation. This ensures the drive can be used confidently in systems where safety is critical. The drive's external encoder feature enhances its capability to monitor and adjust feedback independently of the motor's built-in encoder. The Sercos

Ethernet communication further enhances system coordination by enabling real-time data exchange. It is critical for maintaining optimal performance in industrial automation. Its flexible firmware upgrade options ensure longevity that allows the drive to be customized to specific application needs over time.

Error Code Diagnostic message Typical cause(s) Quick fix / first response
F4012 Incorrect I/O length Master’s cyclic input/output data length doesn’t match the values set in P-0-4071 / P-0-4082 Adjust the I/O-length parameters in the drive or re-configure the field-bus master, then reset the error
F4016 PLC double real-time channel failure Integrated PLC can’t update the RtcW variable in time; RTC task takes longer than its cycle Increase the RTC task interval or the CmdDelay setting in MX_SynchronControl; clear the error
F4017 S-III: incorrect sequence during phase switch Sercos-III master attempted an illegal or mistimed phase change Check Sercos master firmware/config; ensure proper phase-switch hand-shake before re-enabling drive
F4034 Emergency-Stop E-Stop input active, wiring fault, or mis-parameterised digital I/O Remove the E-Stop condition, verify wiring & P-0-0008 settings, then reset and re-enable power
F8022 Encoder 1: signals incorrect (cleared in phase 2) Damaged or loose encoder cable, dirty sensor, or hardware fault on control section Inspect/replace cable & encoder, clean read head, or swap control section if hardware-related
F8025 Overvoltage in power section DC-bus too high—regenerative load, incoming mains overvoltage, or brake resistor sizing issue Verify mains voltage, add/resize braking resistor or braking unit, review decel ramps
F8028 Overcurrent in power section Motor stalled, shorted phase, or load spike exceeded drive rating Check motor wiring & load mechanics; reduce commanded torque/current; inspect power module
F8057 Device overload shutdown Continuous RMS current exceeded; drive overheated Reduce duty cycle, improve cooling, or upsize drive; allow drive to cool and reset
F8064 Interruption of motor phase Open phase in motor cable or internal motor winding break Continuity-test motor leads, connector, and motor windings; repair or replace faulty component
F8120 Invalid control-section / firmware combination  Control section flashed with incompatible firmware version Re-flash correct firmware release or swap control section matching the power section’s firmware

Error Code What It Means
F4012  Incorrect I/O length – master’s cyclic data length does not match the drive’s parameterised length.
F4016  PLC double real-time channel failure – integrated PLC cannot deliver RTcW command data within the required cycle.
F4034 Emergency-Stop activated – E-Stop input pulled low, wiring fault or mis-configured digital I/O.
F8022 Encoder 1: signals incorrect – defective/loose encoder cable or dirty sensor produces invalid feedback signals.
F8023 Mechanical link of encoder / motor connection error – encoder slipped or motor–encoder coupling damaged.
F8025 Overvoltage in power section – DC-bus exceeds safe limit, often during regenerative braking or mains over-voltage. 
F8028 Overcurrent in power section – demanded or fault current rises above rated level; output stage is locked.
F8057  Device overload shutdown – continuous RMS current above drive rating causes thermal overload.
F8060 Overcurrent in power section (short-circuit) – motor or cable short, or defective power module.
F8064  Interruption of motor phase – open phase in motor winding or cable monitored for >30 s.
