Product Description:
Bosch Rexroth Indramat manufactures the CSH01.1C-NN-EN2-NNN-MA1-NN-S-NN-FW in the CSH Advanced Controllers series. This unit is a motion-logic controller intended to coordinate a single drive in industrial machinery. It links operator commands with motor feedback while housing signal conditioning, encoder evaluation, and basic I/O needed for closed-loop automation.
The controller handles one axis; its designation is Single-Axis, letting designers dedicate a separate module to each drive for simplified diagnostics. The onboard digital output group can source up to 500 mA, which is sufficient for driving opto-isolated relays or status lamps without extra amplifiers. Encoder supply on the En2 connector is regulated at 5.0 V with a maximum draw of 350 mA, supporting most absolute or incremental sensors that fit the selected feedback format. Position data arrive through an EnDat 2.1, 1 Vpp, and 5 V TTL interface set, allowing mixed feedback types on the same header while maintaining tight timing for velocity loops. Control-bus sockets remain empty, so fieldbus communication must be added through external interfaces when required.
The Ma1 option card supplies two differential input channels that accept signals within ±10 V and digitize them at 12 Bit resolution; this combination captures process variables with 4.9 mV granularity while presenting 1 MΩ input resistance to minimize sensor loading. Two corresponding analog outputs share the same ±10 V span, can drive loads down to 1 kΩ, and match the 12-bit step size for symmetric command generation. Serial diagnostics and firmware download use RS232, enabling direct laptop connection without protocol converters. Discrete actuation is possible through a form-C relay rated at DC 24 V and 1 A, giving the controller a convenient way to switch brakes or contactors inside the control cabinet without using external interposing relays.
