Product Description:
The CSH01.1C-NN-ENS-NNN-MA1-NN-S-NP-FW is an advanced motion logic controller card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It is designed for installation in IndraDrive power sections. The card manages position feedback, analog measurement, and discrete signaling so multiple drive axes can execute synchronized moves within automated machinery.
The base analog section accepts voltage or current references through an input path that presents a resistance of 160 kΩ, which limits loading on upstream transducers and helps preserve signal integrity. Conversion is performed with a resolution of 12 bit, giving 4096 discrete steps, while the corresponding analog outputs operate at 8 bit resolution for coarse setpoint generation or actuator trim. Digital inputs are read at 24 V / 3 mA to match standard sensor wiring, and the card can source digital outputs rated 24 V / 0.5 A for contactors or lamp stacks. The ENS encoder interface samples differential TTL tracks up to 400 kHz, which supports accurate velocity capture on high-speed spindles. A probe pulse width of 4 µs is recognized for precise edge latching, and relay contacts switch 24 V DC at 1 A for auxiliary signaling.
The ENS port is carried on a D-Sub 15 female connector and operates from an 11.6 V supply, so external encoders require only low auxiliary power. Two MA1 analog input channels present 1000 kΩ impedance, which reduces sensor loading, and two corresponding outputs can source up to 10 mA for valve control. RS-232 maintenance access supports data rates up to 115 kBaud over cable runs of 15 m for local setup and service access without network infrastructure. This combination provides encoder feedback, high-impedance measurement, and serial communication on the same controller card.
