Product Description:

The CSH01.3C-NN-ENS-ENS-CCD-S2-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Mounted behind a power module, it supervises axis motion by processing encoder data, analog references, and probe signals in real time. Within an automation cell, it converts machine-level commands into drive instructions for coordinated speed, position, and diagnostic handling across servo axes. Its dual ENS channels support direct connection to high-resolution encoders, which helps maintain synchronized interpolation during demanding cycle sequences.

The analog front end supports a bandwidth of 1.4 kHz, allowing the control section to follow rapidly changing setpoints with stable response. Incoming analog commands see an input resistance of 160 kOhm, which reduces loading on upstream signal sources and helps preserve signal accuracy. For output actuation, each voltage channel is converted in 10 us and can drive external circuitry with loads down to 5 kOhm while maintaining linear behavior. Its output resolution of 19.5 mV/incr supports fine low-voltage command adjustment. Fast position capture is also supported through probe handling with 1 µs edge accuracy, pulse acceptance down to 4 µs, and rejection of overly long trigger signals above the permitted maximum pulse width.

Base power consumption stays below 8.5 W, which keeps the control section efficient during normal operation. Each digital output can source up to 500 mA for loads such as brakes or contactors, and the output stage can absorb inductive discharge energy without damage. During startup, the supply path tolerates an inrush current of 4 A, so the module can power up without exceeding its intended operating behavior. Each ENS channel applies filtering at 500 kHz to support clean encoder signal handling. The encoder interface also uses a 120 ohm input impedance and an internal 11.6 V supply rail with 500 mA available for connected feedback devices.
