Product Description:

The CSH01.3C-S3-ENS-NNN-CCD-NN-S-NN-FW is an axis and communication expansion card manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in a modular IndraDrive rack, it supervises a single drive axis and passes motion data to higher-level controls. Within an automation line, the board serves as the interface between feedback devices, control signals, and the drive electronics so commanded motion can be executed with stable velocity, torque, and position behavior. Because it is used as part of a controller platform rather than as a standalone drive, it supports coordinated machine motion through the surrounding rack architecture.

It accepts differential 5-volt TTL pulse trains up to 400 kHz, making it compatible with high-resolution incremental encoders routed through the ENS interface and the D-Sub 15 female socket. For analog feedback or process control, the card sources a voltage output of 5 V / 1 mA, while discrete commands are handled through transistor outputs rated at 24 V / 0.5 A. Two dry relay contacts can switch auxiliary loads up to DC 24 V / 1 A. Signal integrity for sine-wave inputs is preserved up to 500 kHz, which helps the card process feedback signals cleanly during fast axis movement and changing operating conditions. This mix of encoder input, analog output, and switched outputs allows the module to exchange status and command signals with nearby machine devices without requiring a separate interface card.

Network traffic is divided between the real-time drive bus and the plant Ethernet backbone. The cross-communication ports X24 and X25 operate as a Master under the IEEE 802.3 standard, providing peer data exchange between neighboring drives. Fieldbus messages pass through the SERCOS III channel by way of an RJ-45, 8-pin socket where the board operates as a Slave to the motion controller. Point-to-point diagnostics are available through the MiniDIN connector that hosts the RS232 service interface, and the card is dedicated to 1 axis so control resources remain assigned to a single motion channel. This separation of network and service connections allows cyclic motion communication and local diagnostic access to coexist within the same controller assembly.
