Product Description:

The CSH01.1C-NN-ENS-MEM-MA1-L2-S-NN-FW module is a control section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed on an IndraDrive platform, it manages motion sequences, I/O processing, and integrated safety functions for servo axes used in packaging machines, material-handling lines, and other factory automation systems. By combining encoder feedback, analog acquisition, and high-speed trigger outputs, the unit forms the programmable core that coordinates position, velocity, and torque regulation of connected motors.

During operation, the control electronics draw a base power of 7.5 W, so cabinet thermal load remains low. The logic rails are supplied from an external source at 24 V DC, and a brief power-up surge reaches 4 A, which must be considered when sizing the auxiliary supply. The housing stands 241 mm high and only 49.5 mm wide, while the depth is 103 mm; these dimensions allow dense stacking of multi-axis drive towers. Two differential analog inputs and two analog outputs are provided through the MA1 option board, each converted with 12-bit resolution for setpoint or process feedback tasks. The MEM extension delivers a 1 MHz output channel that can generate position-synchronized marker pulses for external counters. For field shutdown verification, the module carries a safety acknowledgment output rated at 24 V / 1 A and a safety input that senses 24 V at 3 mA.

Feedback handling relies on an interface supporting IndraDyn/HIPERFACE/1 Vpp/TTL encoders. The dedicated ENS rail delivers 12 V DC at up to 500 mA to the sensor, preventing voltage drop on long cable runs. Functional safety is built in through Safe Torque Off, which removes drive energy within the power section when the certified channel is disabled, so no separate contactor is required. The MA1 analog channels and the MEM timing output support synchronized process signaling and deterministic motion control.
