Product Description:

The CSH01.1C-CO-ENS-NNN-NNN-S1-S-NN-FW is a single-axis drive controller option card produced by Bosch Rexroth Indramat and assigned to the CSH Advanced Controllers series. It is installed in modular Rexroth drive stacks to process command, feedback, and safety signals so that servo axes follow programmed motion profiles. Within an automation cell, the card links fieldbus traffic, encoder feedback, and discrete I/O to the power section to control position, velocity, and torque on packaging, handling, or machining equipment.

Analog processing is handled through two differential inputs that accept a range of ±10 V. The typical input resistance of 160 kΩ minimizes sensor loading and preserves signal fidelity. For actuator commands, the board can source up to 1 mA while holding the analog output within a ceiling of 5 V, making it suitable for reference signals to external amplifiers or meters. Base electronics draw 7.5 W, and an extra 1 W is reserved for CANopen or DeviceNet communication. During power-up, the module momentarily pulls 4 A, so breaker sizing and bus capacitors must accommodate this inrush. A dedicated 6 W rail feeds the encoder interface, while the transducer supply stabilizes at 11.6 V to power incremental or EnDat sensors without separate converters.

Safety and field wiring are segregated on a 24 VDC domain. The fail-safe outputs can deliver a maximum pulse width of 100 ms to downstream contactors, and auxiliary relays are permitted to switch up to 1 A against loads not exceeding 30 VDC. For solid-state safety chains, the board provides up to 1.6 A of source current at a regulated 24 VDC. Serial diagnostics share these connectors; the port sustains cable runs of 15 m and exchanges status frames at rates up to 115 kBaud, enabling parameter tuning from a laptop outside the cabinet. The low-leakage relay design keeps heat dissipation modest and allows dense mounting on multi-axis racks.
