Product Description:

The CSH01.1C-PB-ENS-EN1-CCD-L1-S-NN-FW is a drive and I/O controller module produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Installed in an IndraDrive cabinet slot, it interprets host commands, conditions sensor data, and issues real-time setpoints to connected power sections. By closing the control loop between encoder feedback and motor power, the unit supports coordinated motion in packaging lines, handling robots, and other high-throughput industrial equipment. Its onboard communication buses also exchange status information with supervisory PLCs and plant networks.

One analog input presents 160 kΩ of resistance, which helps prevent signal loading, and the analog output can source 1 mA for external setpoints. Controller electronics draw 7.5 W at idle. Digital outputs can sink 500 mA, so small relays or indicator lamps can be driven directly. Fieldbus traffic moves over PROFIBUS-DP, while synchronized motion data is exchanged on a SERCOS III Master link. Encoder port 1 supports IndraDyn, Hiperface, or 1 Vpp feedback, and port 2 handles HSF or resolver signals. A 12-bit ENS converter processes the second channel and operates from an 11.6 V supply at 500 mA.

Safety-related and auxiliary circuits are supplied separately. The En1 high-speed feedback channel provides a regulated 8 VDC source for the HSF encoder and a differential 18.2 Vpp carrier for resolver excitation. Drive enable acknowledgment is delivered over the 24 V / 1 A L1 Ack line, while motion commands into the power stage are gated by a 24 V logic signal that draws only 3 mA. The controller stop function conforms to Category 0, which means power is removed immediately when the stop input is asserted and all torque production stops without delay. These dedicated supplies and the hardware stop path isolate safety functions from the main control bus so emergency circuits can operate without interrupting deterministic communication.
