Product Description:
The CSH01.1C-NN-EN1-EN2-MEM-S2-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive cabinet, this module supplies axis-level processing, encoder management, and integrated safety for servo drives used in automated machinery, conveyors, and packaging equipment. It mounts beside a power section and handles the signal conditioning that links field sensors, motion feedback devices, and supervisory PLC commands to the drive electronics that energize a motor. By separating control functions from the power stage, the drive can process feedback, command signals, and protective responses within one coordinated assembly.
The housing is only 49.5 mm wide, 241 mm high, and 103 mm deep, so it fits densely populated control panels without taking much rail space. Internal logic and encoder conditioning circuits draw up to 1.1 A, while field devices connected to the terminal block may share a combined I/O source limited to 0.5 A. Option 1 accepts HSF or RSF incremental encoders, and Option 2 processes EnDat 2.1, 1 Vpp sinusoidal, or TTL feedback for applications that use different motor or measuring systems. A single normally open relay with contact form 1 N/O is provided for status signaling and is rated for DC 24 V at 1 A, while the Safe Motion function remains active even when the relay is de-energized.
An analog monitor channel can source or sink signals at 5 V for scope or diagnostic equipment, which allows operating values to be observed directly at the drive. The probe input stage recognizes rising edges at a logic level of 24 V and is protected by a current limiter listed as 3 mA to guard the input circuit during external triggering. Real-time parameter setting and service communication are handled through the built-in RS232 serial interface, and all bus lines share the controller's front connector for simplified wiring. This layout keeps signal access concentrated at the front of the unit and supports orderly integration with adjacent cabinet hardware.
