Product Description:

The CSH01.1C-NN-ENS-NNN-MA1-S1-S-NN-FW controller is manufactured by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. As a modular control card, it is inserted into IndraDrive drive units to execute axis control, process the machine’s field signals, and translate motion profiles into real-time commands. By bridging high-speed encoder inputs, analog conditioning, and discrete I/O, the module functions as the central coordination layer between the drive power stage and the higher-level PLC in industrial automation lines.

At the discrete level, each input circuit is rated for 24 V / 3 mA, a current-limited threshold that guarantees reliable logic-low and logic-high detection from sensors such as proximity switches. Complementary outputs can switch loads up to 24 V / 0.5 A, allowing direct actuation of relays or indicator lamps without an interposing driver. The base analog section can source or sink up to 5 V / 1 mA, enabling low-level reference generation for external amplifiers or monitoring equipment. For fast position feedback, the ENS interface supports frequencies to 500 kHz, which is the maximum incremental encoder pulse rate that can be counted without loss. A 12-bit conversion depth on the MA1 analog input path delivers a resolution of 12 bit, sufficient for fine set-point scaling and error detection in servo loops.

Power and signal integrity are reinforced by a dedicated S1 controller rail that can supply up to 1.6 A, ensuring the onboard logic remains stable during surge events. Safety-related interlocks may be routed through the integrated relay whose contacts are rated at 24 V DC / 1 A, so modest solenoids or brake releases can be switched directly. Dynamic command following is supported by an analog bandwidth of 1 kHz on each MA1 input channel, while the corresponding input resistance of 160 kΩ imposes minimal loading on upstream transducers, preserving signal accuracy across extended cable runs.
