Product Description:

The CSH01.1C-S3-ENS-EN2-NNN-L1-S-K1-FW belongs to the CSH Advanced Controllers series manufactured by Bosch Rexroth Indramat. As a control section for multi-axis drive assemblies, it coordinates motion commands and manages feedback devices. It also exchanges data with higher-level PLCs to keep servo loops synchronized within industrial automation lines. The unit serves as the interface between the power section and the automation system, so command processing and feedback evaluation remain centralized in one module. That arrangement supports coordinated axis behavior when several drives operate together on the same machine.

This controller accepts differential analog commands within a range of ±10 V, and its input stage presents 2 kΩ of resistance, allowing direct connection to standard process transducers without excessive loading. For outbound signals, a 5 V / 1 mA analog channel can feed tachometers or supervisory logic. During power-up, the electronics draw a peak of 4 A as inrush, then stabilize at a continuous base consumption of 7.5 W, which is relevant when sizing cabinet supplies. Digital outputs are rated at 0.5 A each to actuate contactors or indicator lamps. Position feedback from motors is received on the X4 socket, which supports IndraDyn, HIPERFACE, 1 Vpp, or TTL formats. Time-critical axis data is transferred to the master controller over SERCOS III so communication remains synchronized with drive operation.

The second encoder socket, X8, broadens feedback flexibility with EnDat 2.1, 1 Vpp, or 5 V TTL protocols and supplies sensors with 5.0 V at up to 350 mA, while the ENS line furnishes auxiliary encoders with 11.6 V at 500 mA for longer cable runs. Pulse outputs can be stretched to a maximum width of 100 ms, which is useful for gating external counters. Discrete field devices may be switched through an onboard relay that carries DC 24 V / 1 A. A starting lockout safety option prevents unintended energizing of axes until permissive conditions are met. Internal logic supervises these interlocks so that motion is enabled only after the controller confirms encoder supply currents and bus communication integrity.
