Product Description:

The CSH01.1C-PB-ENS-EN1-NNN-S1-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It is a plug-in motion and logic module that docks onto IndraDrive power units to coordinate servo axes in automated machinery. By executing position loops, exchanging fieldbus data, and supervising integrated safety inputs, the module forms the core link between higher-level PLCs and the motor feedback hardware installed on each axis. Its role in the drive assembly allows motion commands, feedback processing, and machine interlocks to be handled from one control platform. That layout helps the drive respond to command changes and status conditions without relying on separate external motion electronics.

Its base power draw is only 7.5 W, so standby heat and supply loading remain low. PROFIBUS communication is handled through an onboard interface that reaches 12 MBaud, providing fast telegram cycles for coordinated motion. Each digital input requires 24 V / 3 mA, allowing standard sensor outputs to drive the logic, while the transistor outputs can source up to 24 V / 0.5 A to actuate contactors or indicators. The start-up sequence imposes an inrush of 4 A, which is useful when selecting upstream protection for the cabinet supply. Input capture electronics accept pulses as short as 100 ms, and the safety-related I/O channels support monitored stop functions within the drive system. These interfaces support routine machine sensors, command devices, and status signaling around the controlled axis.

The primary encoder connector supplies 11.6 V at up to 500 mA, supporting IndraDyn, HIPERFACE®, or 1 Vpp feedback devices directly from the board. An internal relay can switch auxiliary signals up to DC 24 V / 1 A, giving galvanic isolation for alarm or interface circuits. Resolver excitation is generated at 4 kHz with an amplitude of 18.2 Vpp, while a separate 8 V rail powers the secondary feedback port that accepts resolver or HSF transducers. This arrangement lets the controller process different feedback types on the same platform and pass position information to the connected drive functions without additional interface hardware. It also allows mixed motor feedback formats to be integrated in machines that use more than one axis style.
