Product Description:

The CSH01.1C-ET-ENS-EN1-NNN-L2-S-NN-FW control card is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It is inserted into an IndraDrive power section to execute motion profiles, collect feedback from multiple encoder types, and exchange data with the plant PLC. Within an automation cell, the card issues position commands, reads analog process values, and activates safety functions so the inverter, motor, and machine mechanics remain synchronized.

The two differential analog inputs accept signals in the range of ±10 V, and this span lets the drive react to standard process transducers without external scaling. Input impedance is fixed at 160 kΩ, which is high enough to avoid loading sensitive sensor circuits. When the controller sends a reference signal to external equipment, it provides an analog output rated at 5 V, 1 mA, which is suitable for high-impedance receivers such as setpoint generators. Command data and drive diagnostics are carried across the built-in Multi-Ethernet port, which supports EtherNet/IP, PROFINET, and EtherCAT so the same hardware can join different network topologies. For direct on-off actuation, the card furnishes digital outputs rated at 24 V, 0.5 A, allowing it to energize contactors or indicator lamps without relays.

The encoder channel labeled ENS supplies the feedback device with 12 V, while the resolver channel delivers excitation at AC 18.2 Vpp with a carrier frequency of 4 kHz. These dedicated sources remove the need for external power rails and support accurate angle computation. A discrete Safe Torque input monitored at 24 V and 3 mA ties into the integrated safety circuitry, and the primary protective mechanism is Safe Torque Off. When this function is triggered, the controller interrupts gate firing in the power stage to prevent unintended motor force without cycling the main supply.
