MICROMASTER Vector, abbreviated MMV, is the sensorless vector member of the Siemens MICROMASTER family that preceded the MICROMASTER 4 range. It is the small end of a pairing with the larger MIDIMASTER Vector, an IP20 built-in unit covering 0.12 kW to 7.5 kW.
Siemens describes sensorless vector control as letting the inverter hold motor speed across a wide range of load conditions, giving high starting torque and accurate speed regulation without an encoder. Overload is 200 per cent for three seconds and then 150 per cent for sixty, output runs from 0 Hz to 650 Hz, and a built-in brake chopper takes an external resistor.
The supply arrangement decides which unit you have. Single phase 230 V models run to 3.0 kW, all with an integrated Class A filter. A separate 380-480 V filtered range ends in 50 rather than 40, so an order number quoted without its last two digits has not identified the drive.
Sensorless vector control for high starting torque without an encoder
200 % overload for 3 seconds, then 150 % for 60 seconds
Fast Current Limit (FCL) for trip-free operation
Built-in brake chopper for an external resistor, plus DC injection with compound braking
RS485 with USS protocol for up to 31 inverters
PID process control with a 15 V, 50 mA supply for the feedback transducer

Source footnotes: on the 400 V class models, output current ratings are reduced by 10% when operating on mains supply voltages over 460 V; Siemens prints that footnote against those tables only. Motor output ratings refer to a Siemens 4 pole motor, 1LA5 series or equivalent. All 1 AC 230 V Micromaster Vector units include integrated Class A filters.
