Product Description:

The CSH01.1C-PB-ENS-ENS-MEM-S2-S-NN-FW belongs to the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. It is a configurable control section that coordinates motion and safety functions within IndraDrive systems, routing fieldbus data, encoder feedback, and local I/O signals to the power section. In automated machinery, the unit executes position loops, handles safe-motion tasks, and links Profibus networks to motor-mounted encoders. This arrangement lets the control section exchange command data with higher-level PLCs while passing feedback and status information to the connected drive inverter. It is used in automated machinery that depends on coordinated axis control and integrated safety signaling.

The controller’s analog monitor channel has an input resistance of 160 kOhm, so connected sensors place only a negligible load on upstream circuitry. During startup, the unit draws an inrush current of 4 A as bulk capacitors charge, and continuous consumption settles at 7.5 W. Digital control terminals can supply up to 1.1 A for external switches and light curtains. A PROFIBUS interface adds 2 W of internal loss, and each ENS encoder module dissipates 6 W while supporting resolver electronics. The analog output channel delivers 1 mA at 5 V, suitable for scope diagnostics or drive-ready signals. The analog output can also be used for status indication during diagnostics. MEM expansion handles time-critical latch inputs across a permitted line length of 40 m.

During power-on, the inrush pulse lasts 100 ms, matching the drive’s contactor specification. Encoder ports provide a stable supply of 12 V without additional regulators, and the MEM latch card can timestamp events at a maximum rate of 1 MHz, supporting high-speed registration marks. Safe-motion terminals accept a field voltage of 24 V and can source up to 0.5 A to dual-channel feedback circuits. The separate encoder, safety, and latch functions allow the controller to manage feedback and event timing without extra interface hardware.
