Product Description:

The CSH01.1C-S3-EN2-NNN-NNN-L2-S-NN-FW is a plug-in motion control card manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside an IndraDrive power section, it forms the real-time axis controller that links local feedback devices with field networks. Its job in an automation cell is to execute drive-based interpolation, supervise torque limiting, and exchange status data with plant PLCs. By integrating analog sensing, digital machine signals, and high-speed SERCOS III communication, the card reduces external wiring and shortens control loop latency.

The analog front end accepts sensor voltages within a range of ±10 V, and its input impedance of 160 kΩ minimizes loading so that delicate transducer signals are not distorted. When the application needs a reference signal, the card can source 5 V / 1 mA on its analog output channel, which is adequate for potentiometer tracking or excitation of small converters. The base electronics draw 7.5 W during steady operation, yet a power-up surge of 4 A may occur; this inrush is limited to 100 ms to help prevent upstream fuse tripping. Command data and drive parameters move across the built-in SERCOS III interface, giving deterministic cyclic exchange while leaving the RS-232 maintenance port available for setup with cable lengths up to 15 m.

For discrete machine signals, each input channel tolerates 24 V / 3 mA while the sourcing outputs can deliver up to 24 V / 0.5 A to drive contactors or indicator lamps. The secondary encoder socket supplies 350 mA at 5.0 V, which is enough for EnDat 2.1, 1 Vpp, or 5 V TTL feedback heads, and the option board itself is allotted 6 W of internal power. A relay contact rated at DC 24 V / 1 A is present for ready or fault signaling. Functional safety is handled on the drive side through the certified Safe Torque Off channel, and the controller board can close position loops and coordinate actuators across multiple industrial axes.
