Product Description:

The CSH01.1C-PB-EN1-EN2-MEM-NN-S-NN-FW is a single-axis control card produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It fits into IndraDrive power sections and provides processing capability, encoder connections, and a PB fieldbus option so that servo or spindle drives can be controlled directly from higher-level PLCs. In an industrial cell, the card converts motion commands into drive-level signals, monitors connected feedback devices, and exchanges status data needed for coordinated automation.

Its base electronics draw 7.5 W, which keeps continuous power demand low inside the cabinet. The card can source up to 500 mA on its digital outputs, allowing it to operate indicator lamps or relay coils without separate interface amplifiers. Encoder interface EN1 delivers a regulated 8.0 V sensor supply, and the associated resolver channel operates at 4 kHz, which supports stable angle conversion while helping reject low-frequency noise. The secondary encoder port EN2 is intended for transducers with a load of 35 Ω, supporting consistent signal transfer across short cable runs. Additional operating values include an EN1 supply current of 250 mA, an EN2 supply current of 350 mA, and a 100 ms pulse width for onboard watchdog signaling.

During power-up, the module tolerates an inrush of 4 A, after which the PB option adds only a small amount to the steady-state draw. The memory interface drives differential signals at 1 MHz and supports cable runs up to 40 m, which is suitable for many cabinet-to-cabinet links. The second encoder supply is held at 5.0 V for incremental sensors, helping the controller support common feedback devices used with auxiliary measurement channels. Two onboard relays switch 24 VDC control circuits at 1 A, allowing the controller to enable contactors or send fault indications through local control wiring.
