Product Description:

The CSH01.3C-ET-EN1-ENS-CCD-S2-S-NN-FW is a drive controller section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive cabinet, it forms the command layer that interprets network telegrams, evaluates encoder feedback, and controls power-stage switching for servo or spindle motors. The module is intended for automated machinery that requires synchronized multi-axis motion, rapid parameter changes, and integrated safety functions. By placing motion control and communication functions inside the drive stack, it reduces the need for separate external control hardware for routine axis coordination.

On the communication side, the card uses Multi-Ethernet as its primary fieldbus, allowing one hardware profile to support PROFINET, EtherNet/IP, or EtherCAT. Peer-to-peer coordination is handled by IEEE 802.3 Master cross communication, so adjacent drives can exchange setpoints with very little delay. The port follows 100Base-TX signaling and supports cable lengths up to 100 m on shielded twisted pair. Physical access is provided through a single RJ-45, 8-pin connector. Encoder slot 1 accepts a Resolver/HSF transducer, while encoder slot 2 performs standard incremental or absolute evaluation, which gives the controller flexibility when different motor feedback devices are used on the same machine platform.

I/O capability rounds out the module. It provides 2 analog outputs that can deliver ±10 V references, along with four digital outputs for status signaling or sequence control. PWM carrier adjustment reaches 16 kHz, which helps keep motor current ripple low during operation. The En1 resolver channel excites its sensor at 4 kHz with an 18.2 Vpp signal, while the ENS tap supplies 11.6 V at 500 mA for external encoders. Integrated Safe Motion routines supervise speed, position, and torque without additional safety relays, and one normally open relay contact is available for auxiliary enable chains.
