Product Description:
Bosch Rexroth Indramat produces the CSH01.1C-PL-EN2-EN2-MD1-NN-S-NN-FW control section for modular drive systems in the CSH Advanced Controllers series. Installed in a compatible power module, this unit manages motion sequences, field-level signals, and encoder feedback so a connected servo axis can be positioned accurately inside an automated cell. It serves as a central logic and I/O platform between the power section and machine-level commands. This arrangement supports deterministic motor control and real-time signal processing in industrial automation. Because it is a control section, it is intended to work with a matching drive assembly rather than as a stand-alone power device.
The analog monitor channel resolves command voltages down to 19.5 mV/inc, allowing fine scaling of torque or speed references. During idle operation, the control electronics draw only 7.5 W, which helps limit heat buildup inside the cabinet. Each fast-switching digital output can source up to 500 mA, so small relays or interface circuits can be driven directly from the board. For position feedback, the encoder socket accepts EnDat2.1 / 1 Vpp / 5 V TTL formats, allowing the receiver to process either differential sine-wave signals or TTL tracks without separate conversion hardware. The circuit terminates the analog sinusoidal channels with 35 Ω of load resistance, which helps maintain stable signal transmission over standard shielded cables.
At power-up, the controller can tolerate an inrush of 4 A for up to 100 ms, allowing standard cabinet supplies to start the logic section without nuisance tripping. The MD1 circuitry provides 12 × 24 V opto-isolated inputs for devices such as limit switches, reference sensors, or probing signals. A matching group of eight transistor outputs can switch external loads such as valve coils or brake solenoids during machine operation. Two parallel expansion headers provide additional addressable inputs and outputs for sequence control. A form-C relay rated at 1 A is also included for general fault signaling or drive-enable interlocks.
