Product Description:

The CSH01.2C-PL-ENS-MEM-CCD-S1-S-NN-FW is a motion logic control section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed inside IndraDrive power sections, the unit governs axis positioning, fieldbus data exchange, and safety interlocks for medium- and high-performance machinery. By combining PLC functions with drive-resident hardware, it serves as the central coordinator that links operator commands, encoder feedback, and drive PWM generation in industrial automation lines. This arrangement lets the drive process motion commands close to the power stage, which helps maintain responsive control during coordinated machine operation.

Typical continuous power demand is 8.5 W, so cabinet heat rise from this control core remains low. For real-time networking, its cross-communication port operates as a SERCOS III Master, allowing deterministic transfer of position words and process data to multiple drives over fiber or copper rings. This supports synchronized data exchange between axes while keeping motion updates tightly timed. The controller also produces an emulation signal at 1 MHz, letting legacy counters track axis motion without separate pulse generators. Local interlocking is supported by 16 Inputs / 16 Outputs, each scanned by the internal PLC cycle. During startup, the supply draws 4 A for up to 100 ms, a brief surge that affects fuse and power supply selection but does not influence normal operation.

For encoder interfacing, the module supports Incremental and SSI formats through a front-mounted D-Sub 15-Pin connector. Sensors receive 11.6 V excitation at up to 500 mA, enabling simultaneous supply of quadrature and absolute transducers on the same harness. If serial diagnostics are preferred, the Mini-DIN 8-pin RS-232 port streams parameter data at 115 kBaud. Safety logic uses electrically isolated inputs that accept 24 V at 3 mA, two semiconductor outputs rated at 24 V and 0.5 A, and dual relays that switch DC 24 V up to 1 A for enabling contactors. The mix of encoder, serial, and safety connections allows one control section to handle feedback acquisition, legacy signal output, and machine permissive circuits from the same front end.
