Product Description:
The CSH01.1C-SE-ENS-EN2-MEM-S2-S-NN-FW is a single-axis control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed inside an IndraDrive modular drive stack, the card processes motion commands, field feedback, and monitored stop signals needed to coordinate servo axes in industrial automation. By combining communication, encoder handling, and integrated safety circuitry on one board, it provides the real-time interface between higher-level PLCs and the power electronics that drive synchronous or asynchronous motors.
Motion commands reach the control section over the SERCOS II fiber channel, and the board supports a transmission rate of up to 16 MBaud, allowing tight sampling intervals for multi-axis coordination. Diagnostic data can be accessed through the RS-232 port, which accepts cable runs up to 15 m at a maximum speed of 115 kBaud. For analog feedback or torque reference, the card sources up to 1 mA per analog output, while each digital output line can sink or source 500 mA, which is enough to drive contactors or indicator lamps directly. Encoder signal replication is galvanically isolated, so downstream measurement equipment is not exposed to ground loops. Safe Motion logic is also resident on the card and can disable power when monitored limits are violated.
The second encoder channel is supplied with 5 V and can deliver 350 mA to high-resolution EnDat 2.1 or TTL readers. The first encoder channel accepts IndraDyn, HIPERFACE, or 1 Vpp formats without additional adapters. For applications that need duplicated position feedback, the absolute and incremental emulation stream is routed over the MEM connector, and its signals can travel 40 m at up to 1 MHz without timing loss. Relay contacts on the board can switch loads up to 24 V DC / 1 A, which is useful for brake release circuits.
