Product Description:

The CSH01.1C-CO-EN2-NNN-NNN-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat and belongs to the CSH Advanced Controllers series. Installed inside an IndraDrive drive stack, it provides real-time position, velocity, and torque processing for coordinated motion control. It serves as the control layer between machine commands and downstream power modules, allowing motors to follow programmed motion profiles in automated machinery.

The controller accepts differential analog feedback within a span of ±10 V, allowing proportional command signals from external transducers or PLCs. Input accuracy is supported by an impedance of 160 kΩ, which minimizes loading on upstream circuits. When the application must send reference data outward, an analog channel supplies a regulated 5 V / 1 mA source that can power sensors or trim potentiometers. Discrete reactions such as valve actuation are handled by a transistor stage rated for 24 V / 0.5 A, while pulse-type tasks, including step-and-direction outputs, can be timed down to a 100 ms minimum width without loss of recognition.

This version is configured for single-axis coordination, keeping internal processing and parameter lists concise for stand-alone servo loops. Its electronics draw only 7.5 W at idle, reducing enclosure heat and easing power-supply sizing. Fieldbus exchange occurs on a dual-protocol port that supports CANopen / DeviceNet, enabling deterministic communication with higher-level controllers. Feedback from the motor arrives through a multi-format encoder socket that understands EnDat 2.1 / 1 Vpp / 5 V TTL signals, so incremental or absolute measuring systems can be used without additional adapters. Functional safety is provided by the integrated Safe Torque Off circuit, which removes drive energy for emergency stops and lockout routines. Additional resources include a 1.1 A supply line for external sensors, a standard operator panel for local parameter access, and a typical inrush current of 4 A during power-up.
