Product Description:

The CSH01.1C-NN-EN1-MA1-MD2-S1-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat and serves as a drive-based control unit for single-axis IndraDrive assemblies used in automated machinery. It processes motion commands, supervises peripheral signals, and exchanges data with higher-level PLCs during machine operation. This allows the connected servo amplifier to follow precise profiles during production cycles while keeping control functions local to the drive.

This control card is configured for single-axis coordination and draws a base idle power of 7.5 W, which simplifies cabinet thermal calculations. During power-up, the inrush reaches 4 A, so upstream fusing and soft-start contactors must accommodate that short surge. The MA1 analog module offers 2 differential input channels plus two voltage outputs. Each input is digitized at 12-bit resolution over a ±10 V range, enabling precise torque or position feedback from external sensors. Analog updates can be gated so that a single pulse as long as 100 ms can be captured without aliasing during short signal events. The controller has no additional fieldbus option, so the standard SERCOS or EtherCAT slot remains available for a separate communication module.

The EN1 encoder interface accepts resolver or HSF signals and distributes an 8 V sensor supply directly from the board. Discrete machine states are handled by the MD2 module, which provides 16 digital inputs and an equal number of outputs for valve manifolds, limit switches, and interlock relays. A D-Sub 9 female safety connector carries STO wiring to upstream safety relays. Synchronous serial position devices can be connected through the SSI port, where clock frequencies up to 1000 kHz are supported and reliable transmission is specified for line lengths up to 40 m. These limits support integration in packaging, handling, and press-automation systems that rely on mixed encoder, analog, and digital signaling.
