Product Description:

Bosch Rexroth Indramat's CSH01.1C-SE-EN2-MA1-MD1-L2-S-NN-FW is a controller from the CSH Advanced Controllers series intended for use with IndraDrive drive assemblies in multi-axis automation. The unit acts as the control section that executes motion commands, processes feedback signals, and communicates with higher-level PLCs to regulate torque, speed, or position. Within an automation cabinet, it provides the computational layer that links sensor data to power modules and supports coordinated servo operation in packaging lines, printing machines, and general material-handling cells. Because it serves as the controller portion of the drive system, it manages command interpretation and signal coordination while the connected power section delivers motor current.

The control section uses SERCOS II for its bus architecture, exchanging cyclic data with drives at real-time rates suitable for synchronized motion. A base inrush current of 4 A is drawn during power-up, so cabinet fusing must accommodate this brief surge. Steady operation requires only 7.5 W, which helps limit thermal loading in densely packed panels. Position feedback is accepted through the versatile EnDat 2.1 / 1 Vpp / 5 V TTL interface, allowing incremental or absolute encoders to be connected without additional adapter cards. Those sensors receive a regulated supply of 5.0 V, which removes the need for an external encoder power tap and supports the permitted RS-232 service lead length of 15 m.

The board's local I/O complements the field bus with 12 digital inputs for limit switches or probe triggers and 8 digital outputs for contactors, valves, or indicator lamps. Two ±10 V analog inputs and two ±10 V analog outputs share a 5 mV resolution, supporting interface signals for legacy equipment where analog references are still required. Encoder electronics can supply up to 350 mA, which is sufficient for higher-demand feedback devices. For integrated safety, the Safe Torque Off channel is actuated by a 24 V, 3 mA signal and provides feedback through a relay rated at 24 V / 1 A, allowing drive power to be removed through the built-in safety path. This mix of digital and analog connections lets the controller interact with both modern drive networks and auxiliary machine devices on the same platform.
