Product Description:

The CSB01.1C-NN-ENS-MA1-NN-S-NN-FW control section is manufactured by Bosch Rexroth Indramat and belongs to the CSB Drive Controllers series. It is installed in modular drive stacks where it handles signal processing, feedback evaluation, and low-level motion commands for IndraDrive power sections. By translating field-level information from encoders, analog sensors, and serial links into PWM gate signals, the unit coordinates torque, speed, and position loops in automated machinery. Used in packaging lines, printing presses, and material-handling axes, the board provides deterministic control cycles and flexible I/O so machine builders can match mechanical loads with appropriate motion profiles.

It provides 2 differential analog input channels that accept process variables within a range of ±10 V, and the same card offers two analog outputs for drive-controlled reference values. The inputs sample at a current control interval of 125 µs, allowing tight torque regulation on high-dynamic axes. The encoder interface supports IndraDyn, HIPERFACE, 1 Vss, and TTL formats, while an internal supply of DC 11.6 V powers the feedback transducers. The height is 241 mm, the depth is 103 mm, and the board draws an inrush current of 4.5 A when energized. Communication slots are not equipped, so network expansion requires external option modules. A single normally open relay rated at 24 VDC and 1 A provides galvanically isolated status signaling.

For high-resolution velocity loops, the MA1 channel converts internal setpoints with a resolution of 12-bit. Parameter access uses the built-in RS232 serial interface, and this remains the primary host link because the optional fieldbus slot is not equipped. Mechanical integration is simplified by a front profile that measures just 49.5 mm in width, allowing dense stacking alongside other control sections. The control section includes no integrated safety functions, so external circuitry must handle emergency stop or safe torque-off functions.
