Product Description:

The CSH01.1C-CO-ENS-MEM-MA1-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It is a drive controller module that plugs into IndraDrive power sections to coordinate servo axes in industrial automation cells. The unit processes encoder feedback, manages fieldbus traffic, and provides analog references so that connected drives can execute position, velocity, and torque loops for assembly lines, packaging equipment, and material handling stations. In this arrangement, the control section handles signal processing and motion coordination while the matching power section delivers motor power. By integrating communication and safety hardware in one plug-in format, it reduces cabinet space in multi-axis machinery.

Six analog terminals give the module 2 inputs and 2 outputs that can source or sink references within a ±10 V range. Each channel uses 12-bit resolution, providing 4096 discrete counts for parameter scaling. Fieldbus connectivity is handled through CANopen / DeviceNet, enabling cyclic setpoint exchange with PLCs without additional gateway cards. Local interaction is handled through a single-line display on the control panel that shows status words and fault codes. For servo feedback duplication, the controller outputs emulated encoder pulses at 1 MHz, allowing external motion controllers to monitor axis position in real time.

The encoder emulator draws only 20 mA, so it can be wired directly to tracking devices, and its supply is internal, so no separate power line is required. A dedicated sensor bus feeds the attached encoder ports with 12 V, supporting IndraDyn S1, M1, S2, and M2 models, and it can stream both SSI absolute and incremental formats without extra adapters. This arrangement supports direct use with compatible feedback systems in the same drive platform. The integrated Safe Torque Off circuit disconnects gate-drive signals when a safety input opens, eliminating residual motor torque within milliseconds and simplifying compliance with machinery safety standards.
