Product Description:

Bosch Rexroth Indramat manufactures the CSH01.3C-NN-ENS-NNN-CCD-NN-S-NN-FW controller as part of the CSH Advanced Controllers series. The board serves as the primary control core inside Rexroth drive cabinets, translating high-level machine commands into deterministic drive setpoints. It supports parameterization through the Ethernet-based engineering interface and offers a single-line control panel display for on-cabinet status viewing, giving machine builders a compact motion platform for multi-axis industrial automation.

Two analog channels are provided. Each channel sources up to 1 mA, allowing direct connection to high-impedance process inputs without external buffering. Voltage swing is fixed at 5 V, a level that pairs with the drive family’s reference inputs while protecting downstream electronics from overrange. The digital-to-analog section has a resolution of 19.5 mV per increment, so 256 discrete counts span the full range and enable fine torque or speed trimming. On the feedback side, the integrated encoder converter samples incremental signals at up to 500 kHz and uses a 12-bit word width for reliable position capture on fast-moving axes. The control communication slots are not equipped, and the unit does not include safety technology. Encoder evaluation is standard, and a dedicated RS232 service port supports bootstrap and diagnostics.

The remaining interfaces support networked operation. When linked through the cross-communication backplane, the board acts as the master node and exchanges axis data over IEEE 802.3 frames. TTL differential inputs permit direct connection of limit switches or probe tracks, and they are accepted up to 400 kHz without pulse loss. Incremental encoder channels supply the sensor with 11.6 V DC and use a 120-ohm line termination to maintain signal integrity over cabinet runs. These resources let the controller synchronize multiple drives, stream data through the Ethernet-based engineering port, and provide fallback access through the serial interface.
