Product Description:
The CSH01.2C-NN-EN1-NNN-CCD-NN-S-NN-FW is a controller module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Within a multi-axis drive system, this module coordinates motion commands, interprets sensor feedback, and issues drive-enable signals to connected power sections. It is intended for use in industrial automation cells where tight synchronization between servo axes, probing devices, and safety relays is required. The module also helps route command and feedback data between the higher-level control system and the drive hardware so motion responses remain consistent during synchronized machine operation.
The analog interface uses an input resistance of 160 kΩ, which minimizes loading on external transducers, and an output stage that provides a reference of 5 V for downstream converters. The controller electronics draw only 8.5 W while idle, which helps support dense cabinet layouts with limited thermal headroom. Digital I/O lines can sink or source up to 0.5 A, allowing direct actuation of solid-state relays and similar control devices. For high-speed feedback, the EN1 HSF port provides a dedicated supply of 250 mA at 8 V DC. The returned HSF signal is processed at a 1.0 V amplitude without external conditioning, which simplifies feedback integration. Time-critical measurements such as tool-touch detection are accepted on the probe channel with pulse widths down to 4 µs. Resolver excitation is generated internally at 4 kHz and 18.2 Vpp, so the module can interrogate single-turn or multi-turn position sensors without separate signal conditioners.
Power-up behavior is limited by a maximum inrush current of 4 A that lasts no longer than 100 ms, which reduces stress on upstream circuit breakers and control power supplies. The onboard relay can switch DC loads up to 1 A DC while observing the 30 V DC contact voltage rating. This makes the relay suitable for brake circuits, contactors, and safety interlocks that need local switching from the controller module. The combination of controlled startup current, relay switching capability, and fast signal handling supports drive-enable logic and auxiliary load control without requiring separate interface boards.
