Product Description:

The CSH01.1C-PL-ENS-NNN-MD1-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. As a plug-in component for IndraDrive power modules, it supplies axis-specific processing, blends feedback from multiple encoder formats, and issues motion commands to attached inverters. The unit is intended for industrial automation tasks such as packaging, material handling, and machine tools where synchronized positioning and speed regulation must be executed deterministically under centralized control. Its role is limited to control, feedback handling, and command processing, while the associated power section supplies motor current to the connected axis.

Communication with the host PLC is handled through a Parallel Interface, giving the drive immediate access to setpoint words and status bits with minimal protocol latency. A front-mounted Single-Line Display presents state codes and diagnostics without opening the cabinet. Encoder reception is flexible because the ENS channel accepts IndraDyn S, HIPERFACE, EnDat 2.1, 1 Vpp, and 5 V TTL formats, and the transducer is powered from the ENS supply at 12 V through a D-Sub 15 female socket. For local service access, the board offers an auxiliary RS232 serial port. Machine safety is integrated via the drive-internal Safe Torque Off function, allowing energy removal from the motor windings when the external safety system demands it. This combination allows one control section to manage motion control, encoder evaluation, and local diagnostics in the same assembly.

The PL expansion edge provides discrete process coupling, and its wiring lands on a D-Sub 37 connector that is segregated from control electronics by galvanically isolated optocouplers to reduce ground loops. On this port, the controller provides up to 16 digital outputs and supports an equal number of selectable inputs, all referenced to a 24 V level that aligns with common industrial sensor supplies. A separate MultiMediaCard slot stores user parameters and other operating data, while the safety channel wiring terminates on a D-Sub 9 female plug to simplify segregation inside control cabinets. This arrangement keeps process I/O, safety wiring, and motion control connections organized within the same control section.
