Product Description:

The CSH01.2C-PL-EN2-EN1-CCD-S1-S-NN-FW is a single-axis control card from Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. It mounts inside an IndraDrive power section, where it executes position, velocity, and safety logic for one servo or spindle axis. By combining encoder evaluation, discrete I/O handling, and network interfacing on one compact board, the unit supports motion-control integration in packaging machines, material-handling cells, and similar industrial equipment. Its role is to manage axis control functions while the paired power section handles motor energy conversion.

The controller’s base consumption is limited to 8.5 W, helping keep enclosure heating low. Command data are exchanged locally through a parallel interface that uses the IEEE 802.3 cross-communication standard for deterministic timing. Encoder 1 can source up to 350 mA at 5.0 V to support EnDat 2.1, 1 Vpp, or 5 V TTL feedback devices, and input filtering helps suppress electrical transients. During power-up, the drive section sees an inrush of 4 A, so the upstream supply must tolerate that short-term demand. Motion-enable commands can be gated by a maximum pulse width of 100 ms, which supports rapid shutdown after fault detection. The board also includes a D-Sub safety connector for direct integration of protective circuits.

Encoder 2 is supplied with 8.0 V and supports resolver or HSF transducers; resolver inputs use 9.0 V excitation, while HSF channels use a 1.0 V carrier. Discrete control signals are routed through the parallel I/O block, which provides 16 In / 16 Out for machine-level interlocks and status exchange. The integrated safe torque off circuit sources up to 24 V / 0.5 A and monitors a 24 V, 3 mA input, allowing shutdown without external relays in suitable system designs. This arrangement allows the controller to react to interlocks while maintaining closed-loop feedback processing for the connected axis.
