Product Description:

The CSH01.2C-PL-EN2-NNN-CCD-NN-S-NN-FW control section is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. As a modular motion-logic controller, it plugs into an IndraDrive power unit and supervises position, velocity, and torque loops for multiple servo axes in automated machinery. By processing feedback in real time and distributing synchronized commands, the unit forms the core of packaging lines, printing presses, and assembly cells that depend on deterministic control.

The controller operates from a DC 24 V control supply and its electronics draw a base load of 8.5 W, limiting cabinet heat. Each analog channel resolves setpoint steps at 19.5 mV/inc, so drive commands can be fine-tuned without dithering. Up to 16 parallel inputs accept hard-wired triggers such as limit switches, while the complementary outputs mirror machine states. Axis coordination across drives is handled through the SERCOS III Master cross-communication port, and additional diagnostics are available over the Ethernet X26 engineering interface. The analog output permits a 5 kΩ load, the maximum pulse width is 100 ms, and each digital output can supply 500 mA.

The digital logic is supplied with 1.1 A to power opto-isolators and driver transistors, and total sourcing capacity for grouped outputs reaches 1000 mA. Position encoders connect to the multifunction interface that supports EnDat 2.1 / 1 Vpp / 5 V TTL, allowing mixed feedback types on the same platform. Field devices that need relay isolation can be switched through contacts rated at DC 24 V, 1 A, ensuring adequate inductive load handling. During startup, the section can draw up to 4 A of inrush, so supply fusing must accommodate this transient. Control signals can be routed over the built-in parallel interface, keeping motion updates independent from the main fieldbus.
