Product Description:
The CSH01.3C-SE-EN2-EN2-CCD-S2-S-NN-FW is a motion control section manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It serves as the command module inside an IndraDrive system. It closes the control loop between drive electronics and higher-level automation so that a single servo axis can be positioned, synchronized, or safeguarded in real time on production machinery. This arrangement lets the controller coordinate motion functions directly with the associated power section and feedback devices.
The unit is rated for 1 axis, so it is intended for a single servo channel. Internal logic is powered from a 24 V DC control supply that keeps parameter memory and safety monitoring active even when the power stage is de-energized. Torque demand is refreshed every 62.5 µs within the current-control loop, while the speed regulator updates at 125 µs to maintain stable velocity under load changes. Position commands are recalculated every 250 µs, matching the minimum network frame so that the controller can keep pace with a Sercos ring without overrun. That update structure supports responsive correction when commanded speed or load conditions change quickly. Pulse-width modulation to the power stage can switch up to 16 kHz, which helps reduce audible noise and improve motor smoothness.
The housing measures 241 × 49.5 × 103 mm, allowing high cabinet density where multiple controllers share a common DC bus. Two feedback ports accept 2 × EnDat 2.1 / 1 Vpp / TTL encoders for dual-loop accuracy or redundancy. Local process interaction is handled by 7 DI / 4 C-I/O / 1 AI / 2 AO / 1 RO, which can reduce the need for separate I/O hardware for simple sensing and actuation. Functional safety reaches Cat. 3 PL d / SIL 2 when the Safe Motion option is active, allowing limited-speed and safe-stop modes through internal logic rather than external relays alone. Master communication runs over Sercos II, and a cross-communication drive port links adjacent axes for time-critical coupling. This layout supports coordinated operation between neighboring drive sections during tightly timed machine sequences.
