Product Description:

The CSH01.1C-PB-ENS-ENS-NNN-S1-S-NN-FW is a single-axis control section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. It occupies the command slot in an IndraDrive system, executing motion profiles, monitoring feedback, and forwarding fieldbus data to the higher-level PLC. By combining a PROFIBUS communication plug-in with dual encoder channels and integral safety I/O, the unit coordinates servo performance and machine-level interlocks in packaging lines, material-handling stations, and assembly cells.

The controller’s base electronics draw 7.5 W, which is the continuous power that must be supplied by the drive’s internal low-voltage bus. Initial energizing demands a peak of 4 A for 100 ms; this inrush value affects circuit breaker sizing and bus capacitance. Command exchange with the host automation system uses the PROFIBUS interface, so telegram timing, addressing, and diagnostic services follow that fieldbus standard. Analog diagnostics are available through a buffered output rated at 5 V, 1 mA, which is suitable for oscilloscope monitoring without loading the source signal. Local discrete control follows the IEC 61131 Type 1 standard, meaning the input circuits recognize the standard 24 V logic levels common to industrial sensors.

Supplementary modules add to overall power consumption and affect safety behavior. Each additional ENS feedback board adds 6 W to the low-voltage budget, so multi-encoder configurations require larger power reserves. The safety input channels accept switching signals at 24 V / 3 mA; they supervise guard doors or emergency stops before releasing torque. Safe shutdown outputs can source up to 24 V / 0.5 A, allowing direct actuation of contactors in smaller axes. For higher currents, the integrated relay contacts are rated at 24 V DC / 1 A, providing a hardware path to interrupt motor power when Safety Technology I/O functions trigger. Supply rails, fuses, and wiring must remain within these limits during operation.
