Frequently Asked Questions
Q1: What is the difference between 3RW51 and 3RW52?
A: Main hardware functions are identical. Differences lie in control supply voltage and interface version. Confirm full model suffix before ordering.
Q2: Is communication module included?
A: Communication module is sold separately as an optional accessory, not pre-installed on the main unit.
Q3: Does it support inside-delta connection?
A: Yes. Inside-delta wiring greatly expands available power for large motors.
Q4: Can PTC temperature sensor be connected?
A: Yes, PTC thermistor can be connected to monitor motor winding overheating.
Q5: Warranty & delivery?
A: Genuine Siemens with manufacturer warranty. Datasheets, selection guides, CAD drawings and quotations available.
