Product Description:

The CSH01.1C-NN-EN2-NNN-MD1-L1-S-NN-FW control section is built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Designed to mount on IndraDrive power bases, it acts as the logic core that executes motion sequences, processes feedback, and exchanges data with PLCs over encoder and fieldbus links. In multi-axis installations, the module provides the timing needed for coordinated positioning, so machine builders can integrate servomotor, spindle, and auxiliary axes through a single compact controller.

The unit offers one analog input that accepts a range of ±10 V for velocity or torque commands. Eleven base digital inputs, shown here as 11, are available for limit switches, sensor flags, or homing triggers, while four base digital outputs drive status lamps or interlocks. Analog results are issued on two configurable outputs, and overall logic consumption stays at 7.5 W. Position feedback is handled through a multi-protocol interface that supports EnDat 2.1 / 1 Vpp / 5 V TTL, giving flexibility for incremental or absolute encoders. That interface is powered by an isolated 5.0 VDC supply to preserve signal integrity when long motor cables are used.

The encoder channel can source up to 350 mA, allowing headroom for multi-turn devices with integral electronics. An optional MD1 expansion adds 12 additional digital inputs and eight digital outputs, and each output group is rated at 24 VDC, 0.5 A for solenoid or relay coils. Safety interlocking is addressed through the integrated starting lockout that conforms to Stop Category 0, providing immediate power removal on emergency request. Separate dry contacts are present for field isolation and are specified for 24 VDC at 1 A. A single-line operator display is included for parameter access, and it draws only 1 W from the internal supply, so the controller can be powered from small auxiliary transformers without exceeding cabinet thermal limits.
