Product Description:

The CSH01.1C-PL-ENS-ENS-NNN-S2-S-NN-FW controller board is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive modular drives, the board executes axis control algorithms, processes field feedback, and distributes motion commands to connected power stages. By combining high-speed encoder evaluation with deterministic logic, the unit coordinates servo motors and safety inputs inside automated assembly lines, pick-and-place robots, and CNC auxiliary axes.

An analog reference channel with an input resistance of 160 kΩ reduces loading on external PLC signal cards. The command voltage is reproduced at the auxiliary output with a resolution of 19.5 mV, giving fine adjustment over drive setpoints. Base electronic demand is 7.5 W, so cabinet thermal planning remains straightforward. The dedicated ENS feedback port filters signals at 500 kHz to suppress aliasing while still supporting differential inputs with an internal resistance of 120 Ω and a supply of 11.6 V at 500 mA. For single-ended TTL sensors, the same socket can capture edges up to 400 kHz, allowing high-speed spindle or linear scale monitoring.

Startup stress on the DC bus is limited by an inrush current of 4 A held for a maximum of 100 ms, protecting upstream fusing. Touch-probe inputs register transitions with 1 µs edge accuracy and accept pulses as short as 4 µs, permitting precise synchronizing to external events. The RS-232 maintenance port supports cables up to 15 m and data rates up to 115 kBaud for diagnostics and service access. SafeMotion channels draw 3 mA on request signals and can switch loads up to 0.5 A, so safety relays, brakes, or contactors can be driven directly without extra interposing hardware.
