Product Description:

The CSH01.2C-PL-EN1-EN2-CCD-S1-S-NN-FW is a single-axis control module built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in modular drive racks, the module interprets encoder feedback, generates reference signals, and exchanges diagnostic data with higher-level PLCs so that servo drives follow commanded motion profiles in automated machinery. Its control functions are intended for coordinated axis operation where motion response and signal handling must remain consistent across the drive system.

An analog monitor channel delivers a reference of 5 V, while the internal electronics draw only 8.5 W at base load to help limit cabinet heat. The CCD communication port follows the IEEE 802.3 standard and connects through a 100Base-TX engineering interface for setup and diagnostics. Separate encoder rails supply 8 V to HSF transducers and can source up to 250 mA, which helps maintain stable feedback operation with long cable runs. A 24 VDC logic bus powers sixteen digital inputs and sixteen transistor outputs in the PL section, and each point is isolated from the drive power stage to reduce ground-loop effects.

The field-wiring side is fed by an isolated supply, and surge energy remains within normal limits when the engineering cable does not exceed 100 m. Relay contacts on the safety channel can carry up to 1 A for interlocking external contactors, while logic monitoring draws 3 mA at the safety inputs and drives 0.5 A at the safety outputs. The resolver input uses an analog track limited to an upper cutoff of 18 kHz, which helps reject high-frequency noise while preserving phase resolution at higher motor speeds. Matching sixteen-channel input and output groups also simplify address mapping in the control system, and the typical 4 A inrush figure can be used when selecting branch protection.
