FAQ
Q1: What advantages does 3RW55 have over 3RW51/52?
A: It supports torque-controlled starting, equipped with STO safety function, higher power rating and stronger resistance to heavy impact loads, suitable for crushers, mills and high-shock loads.
Q2: What is STO safety function?
A: Safe Torque Off, it cuts off motor drive torque to comply with machinery safety standards for safety-related equipment.
Q3: Does it allow frequent start-stop cycles?
A: It permits higher start-stop frequency than other series, but still has limits. Upsize model for extremely frequent operation.
Q4: Does it support inside-delta connection?
A: Yes. Inside-delta wiring is recommended for high-power models to reduce device current.
Q5: Supply & documents?
A: Brand new genuine Siemens with manufacturer warranty. Selection manuals, 3D/CAD drawings, certificates and quotations available.
