Product Description:
The CSH01.1C-S3-NNN-MA1-MD1-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Designed for multi-axis motion tasks, it mounts into IndraDrive power units and coordinates servo drives over a Sercos III network. By providing analog, digital, and safety interfaces in one compact slot, the module consolidates axis control, fast fieldbus communication, and safe torque-off functions inside a single automation rack. It also serves as the interface layer between the drive electronics and external machine signals, which reduces the need for separate interface modules in modular drive assemblies.
Power consumption for the logic electronics is limited to 7.5 W, so cabinet thermal loading remains low. At startup, the module draws an inrush of 4 A, a figure used when sizing supply fusing and wiring. The MA1 analog board offers 2 analog input channels, and each input operates over a symmetrical ±10 V span with 12 bit resolution. Matching analog outputs use the same resolution, which supports consistent scaling between incoming process signals and outgoing command values. This range is common in industrial sensors and actuators, so the control section can be integrated into existing analog signal paths without extra conversion hardware.
Discrete handling is supplied by the MD1 board, which provides 12 digital inputs, 8 digital output channels, and a minimum pulse width of 100 ms to filter bounce on time-critical signals. Network traffic is routed through an RJ-45, 8-pin port that conforms to the IEEE 802.3 standard used by Sercos III, allowing the module to exchange real-time drive data over Ethernet-based cabling. For safety, the integrated STO circuit provides a feedback contact rated at DC 24 V / 1 A, and the control path accepts 24 V at 3 mA through a D-Sub, 9-pin connector for connection to external emergency stop chains. This safety wiring remains separate from ordinary command traffic, which helps keep the emergency stop path clear and direct.
