Product Description:
The CSB01.1C-PB-ENS-EN2-NN-S-NN-FW is a control section manufactured by Bosch Rexroth Indramat for the CSB Drive Controllers series. Installed in an IndraDrive power frame, it supervises one servo axis and exchanges motion commands with higher-level PLCs. Inside an automation cell, the module converts fieldbus telegrams into pulse patterns for the power stage, letting machine builders coordinate positioning, speed, and torque loops without external relay logic.
This unit governs a single motion channel, so its control architecture is tailored to 1 axis. Bus communication is handled through PROFIBUS-DP, allowing deterministic cyclic data exchange with typical update times below a millisecond. Two incremental and absolute feedback paths are available; Interface 1 supplies IndraDyn, HIPERFACE, 1 Vpp, or TTL signals while Interface 2 accepts EnDat 2.1, 1 Vpp, or 5 V TTL formats. Each transducer port delivers up to 300 mA from an 11.6 V source, eliminating the need for external encoder power. The internal processor can refresh PWM outputs at a maximum switching frequency of 8 kHz, giving adequate current loop bandwidth for most rotary or linear servomotors. Control electronics draw only 22 W, so cabinet thermal load remains low even when three general-purpose digital inputs and the solitary normally open relay contact are active.
The unit has a depth of 103 mm, a height of 241 mm, and a width of 49.5 mm, which permits dense vertical stacking beside companion power modules. During power-up, the circuitry experiences an inrush of 4.5 A for 110 ms, so fuse sizing and supply wiring must accommodate this short peak without excessive voltage sag. One RS-232 service port supports diagnostic access, while the combined total of three configurable I/O points lets the controller interface with limit switches or drive-ready signals without an auxiliary card.
