Why Choose Siemens Frequency Converters
- Wide power range — from 0.1 kW (SINAMICS G110) to 900 kW (SINAMICS G150): solutions for every industrial scale.
- Safety: STO (Safe Torque Off) — hardware safety function in the G120 series, certified to SIL 2 / PL d.
- Modbus RTU / PROFIBUS / PROFINET — broad communication options for SCADA and Siemens S7-1200/S7-1500 PLC integration.
- Embedded PLC (DCC) — the G120 supports Drive Control Chart programming for simple automation tasks without an external controller.
- Energy savings — the P/N (pump and fan) mode reduces energy consumption by up to 30 % versus direct motor starting.
How to Select a Siemens VFD
- Motor power (kW) — the drive rating should match or exceed the motor nameplate power by 10–20 % under heavy starting conditions.
- Supply voltage — for a single-phase 220 V network choose SINAMICS V20 or MicroMaster 420/440; for three-phase 380 V the full lineup is available.
- Load type — for pumps and fans choose V20 or MicroMaster 430; for hoisting and textile machinery choose MicroMaster 440 or G120 with vector control.
- Communication interface — if PLC integration is required, select the G120 with an optional PROFIBUS or PROFINET module.
