Product Description:

The CSH01.1C-S3-EN2-EN1-NNN-S2-S-NN-FW is a single-axis control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It plugs into IndraDrive power sections and governs servo or induction motors through its internal processor and the SERCOS III real-time bus. Within an automation line, the module executes position, velocity, and torque loops while passing status data to higher-level PLCs, so it serves as the central motion node. The product integrates field-oriented control algorithms and built-in safety functions for machine control tasks, and it supports coordinated motion in packaging, handling, and general automation equipment.

At the analog front end, an input resistance of 160 kΩ minimizes sensor loading, and the converter processes incoming voltages at 1.23 mV/inc for precise monitoring of external transducers. The module’s core electronics draw only 7.5 W, which simplifies cabinet thermal calculations during continuous operation. Standard 24 V control wiring is accepted; each digital input loads the source with 24 V / 3 mA, and the transistorized output can source up to 24 V / 0.5 A for contactors or indicator lamps. For resolver-equipped motors, the En1 channel excites the rotor coil at 4 kHz, and all process data are exchanged through dual RJ-45 ports on the deterministic SERCOS III network.

The resolver link uses an excitation amplitude of 18.2 Vpp, while the secondary encoder port supplies 5.0 V at up to 350 mA for EnDat 2.1, TTL, or high-speed feedback devices. This arrangement supports motors that use different feedback formats on the same drive platform. During power-up, the drive withstands a 4 A inrush surge before settling to the consumption noted earlier. Safe Motion functions supervise windowed speed, standstill, and braking tasks, and the built-in relay forwards a safe-torque-off confirmation to external circuits. An eight-pin RJ-45 connector completes the SERCOS III channel, allowing synchronized communication without a separate interface card.
