Product Description:

The CSH01.1C-PB-ENS-MEM-MA1-NN-S-XP-FW motion control unit is produced by Bosch Rexroth Indramat as part of the CSH Advanced Controllers series. It is intended for IndraDrive platforms, where it coordinates servo axes, manages fieldbus communication, and supports precise motion control across multiple machine functions. The controller processes command and feedback data in real time so that positioning, synchronization, and speed regulation remain consistent in packaging, material handling, and processing equipment. Its role is centered on control and signal handling rather than power conversion, which allows it to serve as the logic interface within a larger drive system.

Communication with higher-level PLCs is handled through PROFIBUS, and the network connection uses a D-Sub 9-pin female connector on the front edge of the housing for accessible integration inside a drive stack. During idle operation, the electronics draw only 7.5 W of base power, which helps limit heat buildup in compact control cabinets. The enclosure measures 241 × 49.5 × 103 mm, allowing the module to fit into the stack without increasing the overall installation footprint. Encoder emulation signals are routed through a channel that is galvanically isolated, which helps reduce ground loop errors between the controller and downstream drive amplifiers. Because the emulation stage is powered internally, no external supply is required for this function. The unit is supplied with a standard control panel for parameter access, and it does not include an integrated safety option.

The MA1 analog module fitted to this controller provides two differential ±10 V input channels and two ±10 V output channels, allowing analog signal exchange with compatible external devices. Both input and output directions are processed with a 12-bit converter, giving 4,096 discrete steps for each signal and supporting stable signal resolution in control tasks. Position feedback enters through the primary interface, which accepts IndraDyn, HIPERFACE, 1 Vss, and TTL formats for broad encoder compatibility. Encoder power is supplied at 12 V directly from the board, so connected feedback devices can be supported without a separate local source. Absolute and incremental formats can also be emulated for legacy drives when compatibility with existing system hardware is required.
