Product Description:
The CSB02.1B-ET-EC-EC-S4-EM-NN-FW drive controller is manufactured by Bosch Rexroth Indramat as part of the CSB Drive Controllers series. Intended for cabinet installation next to power modules, it hosts the real-time logic that supervises position loops, gathers sensor data, and exchanges status information with higher-level PLCs. Integrating this unit into an automation cell allows coordinated motion of servo or spindle axes while keeping wiring concentrated in the control enclosure and minimizing panel space requirements.
The controller operates from a DC 24 V control supply and its electronics draw only 17 W at idle, supporting energy-efficient standby modes. Machine signals enter through 11 digital inputs that can be paired with 5 configurable digital I/O points for flexible interlocking schemes. For analog processing, the board provides 3 differential input channels and 2 voltage-scaled outputs, enabling speed demand and torque feedback to be exchanged with external regulators. Two probe inputs capture edge-triggered events, while twin encoder interfaces allow incremental or absolute feedback to be routed directly to the drive. A digital output block can source up to 500 mA to actuate relays, and three modular option slots are available so extra functionality can be added without replacing the core hardware.
Network connectivity is handled by the Multi-Ethernet (ET) platform that supports real-time variants over the same physical interface. The board exposes an 8-pin RJ-45 connector built to the IEEE 802.3u Fast Ethernet standard, simplifying integration with managed industrial switches. Position data from linear or rotary transducers can be forwarded through an SSI absolute emulation channel for deterministic exchange with the PLC. Functional safety is provided by the Safe Motion (S4) package, which continuously evaluates velocity and position parameters and can trigger an immediate shutdown through the dedicated output line when predefined thresholds are exceeded.
