Product Description:

The CSH01.3C-NN-EN1-MA1-CCD-NN-S-NN-FW is a motion and logic controller module produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in drive racks of IndraDrive systems, the module coordinates axis positioning, analog and digital signals, and field communication in automated machinery. As a plug-in option for multi-axis converters, it closes the servo loops locally and forwards status data to supervisory PLCs, which helps simplify the control architecture of packaging, handling, and processing equipment.

It provides 2 differential analog inputs that allow noise-reduced measurement of process variables. Two voltage outputs are available, and each can source or sink signals across a range of ±10 V. With a conversion granularity of 5 mV/inc, fine actuation of valves or reference channels is possible. The outputs are designed for loads down to 1 kΩ, enabling direct connection to standard drive inverters. The controller also has four configurable digital lines, so small sensor-actuator groups can be wired without an external I/O module, while the differential input design helps reject common-mode interference picked up over long cable runs.

For controller housekeeping, the unit draws 8.5 W from the 24 V internal bus. Each current loop for the drive axes is refreshed every 62.5 µs, and pulse patterns to the power stage can switch up to 16 kHz, which helps minimize torque ripple even with high-speed motors. Cross-communication between neighboring drives takes place through the IEEE 802.3 interface, while parameter access through the RS-232 service port operates at 115 kBaud across cables up to 15 m. Position feedback is accepted through a resolver or HSF encoder, with an 8 V sensor supply and 18.2 Vpp excitation at a 4 kHz carrier to support stable angle information for synchronous control.
