Product Description:

The CSH01.1C-NN-ENS-EN2-MD1-S1-S-NN-FW is a drive controller card built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in modular Rexroth servo systems, it executes axis calculations, manages feedback data, and distributes enabling signals so that connected drives follow programmed motion profiles. By combining position control, field-level diagnostics, and machine-safety supervision on one plug-in board, the unit simplifies cabinet wiring in industrial automation cells. This arrangement keeps control, feedback, and safety functions together within the same controller section of the drive system.

During standby, the card draws only 7.5 W, which helps limit heat buildup inside compact enclosures. One analog monitor channel can source or sink up to 5 V / 1 mA for feedback tasks that require a continuous reference signal. The MD1 expansion provides 12 opto-isolated digital inputs and 8 sourcing transistor outputs, while each output can switch up to 24 V / 0.5 A for relays or indicator lamps. High-speed command exchange with legacy HMIs is supported through an RS-232 port that reaches 115 kBaud. Embedded power rails also feed the encoder interfaces, with the EN2 channel supplying 5.0 V at 350 mA for TTL encoders and the ENS channel supplying 11.6 V for sin-cos sensors, so separate external supplies are not required.

An initial energizing surge of 4 A must be allowed for at power-up before normal operating demand settles. After startup, the auxiliary ENS rail can continuously deliver 500 mA to connected feedback devices. The controller watchdog can generate an enable pulse up to 100 ms wide, giving downstream drives time to latch safe torque-off signals before power is removed. Dedicated safety I/O blocks monitor emergency-stop loops and switch external contactors without extra relays. These functions support coordinated shutdown behavior while keeping safety signaling integrated with the main control card.
