Product Description:
The CSH01.1C-PB-ENS-EN2-NNN-L2-S-NN-FW is a single-axis control section from Bosch Rexroth Indramat in the CSH Advanced Controllers series. Installed in an IndraDrive modular rack, the unit processes motion commands, supervises encoder feedback, and issues drive-ready signals for industrial automation tasks across coordinated servo axes. By combining analog inputs, digital outputs, fieldbus communication, and an integrated safety circuit, the card coordinates velocity, position, and torque loops for packaging, printing, and material-handling lines. This arrangement lets one rack slot handle command processing, feedback evaluation, and control-state signaling for a single drive axis.
The module is 49.5 mm wide, 241 mm high, and 103 mm deep, which simplifies cabinet planning. Two differential analog channels accept command signals over the range of ±10 V, and their high input impedance of 160 kΩ helps prevent loading of upstream controllers. The differential input format also helps reduce the effect of electrical noise on low-level command wiring. For status indicators or coil actuation, the integrated digital driver supplies 24 V, 0.5 A per channel. Encoders connect through the factory-installed IndraDyn, HIPERFACE, 1 Vpp, and TTL interface, while a second connector supports EnDat 2.1, 1 Vpp, and 5 V TTL feedback for mixed-sensor installations without auxiliary modules. A repeater section with 350 Ω output resistance and a 5 V, 75 mA supply helps preserve signal integrity along extended encoder cables.
The control section exchanges data with higher-level PLCs over PROFIBUS, and the master port sustains a throughput of 12 MBaud for deterministic setpoint and diagnostic cycles. This communication path supports cyclic control data exchange between the drive system and the automation controller. Drive-integrated safety relies on the Safe Torque Off function, which is assessed to SIL3 / Cat. 3 PL e. STO is activated by a 24 V, 3 mA control line, and its state is delivered on a dedicated 24 V, 1 A acknowledgment output so redundant monitoring circuits can react without extra relays.
