Product Description:

The CSH01.3C-ET-ENS-ENS-CCD-NN-S-NN-FW is a single-axis control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It mounts on IndraDrive power modules and supplies the control functions that close motion loops in industrial automation cells. The board interprets encoder signals, handles analog and digital I/O, and exchanges process data with higher-level PLCs through its integrated Ethernet port. In a coordinated drive system, it determines setpoints in real time so conveyor axes, pick-and-place actuators, and tooling spindles remain aligned with the master sequence. This lets the drive react quickly to changes in load, position, and command values during synchronized machine operation.

Two ±10 V analog command channels present a high input impedance of 160 kΩ, reducing load on upstream sensors. The module can retransmit position or process variables through an analog output limited to 1 mA, which helps protect delicate instrumentation. For discrete control, each digital output can source up to 0.5 A, enough to drive contactors or opto-isolated relays directly. Control communication uses Multi-Ethernet, and network traffic passes through an RJ-45 8-pin socket that meets the 100Base-TX standard. Quadrature and SSI feedback are processed by a 12-bit converter, and the encoder path supports frequencies up to 500 kHz while a 120 Ω terminator suppresses reflections.

Two ENS channels provide additional feedback capacity and share a D-Sub 15 female connector supplied with 11.6 V at 500 mA. The TTL interface captures incremental edges up to 400 kHz, accommodating high-resolution linear scales and fast rotary encoders. When peer setpoint exchange is needed, the Option 3 feature enables Cross Communication, linking controllers across the backplane without external cabling. A changeover relay on the card is rated for 1 A and can be used for brake release or alarm signaling.
