MIDIMASTER Vector, abbreviated MDV, is the large enclosed member of the Siemens sensorless vector range that preceded the MICROMASTER 4 generation. It shares a control platform with the smaller MICROMASTER Vector but is a physically different product. Every rating is published twice, for constant torque and for variable torque, reaching 75 kW and 90 kW respectively.
Three voltage classes are offered: 208-240 V, 380-500 V and 525-575 V. Control is sensorless vector with Flux Current Control, overload is 200 per cent for three seconds and then 150 per cent for 60 seconds, and output frequency runs to 650 Hz.
One model designation covers three physically different builds, and only the order number separates them: a suffix of 40 is IP21 to NEMA 1, 50 is IP20 to NEMA 1 with an integrated filter, and S45 is IP56 to NEMA 4/12. The MDV lists no built-in brake chopper, so a braking fault may sit in the separate Siemens Braking Unit.

Order numbers shown are the IP21/NEMA 1 versions. IP20/NEMA 1 units with an integrated filter use the suffix 50 and IP56/NEMA 4/12 units use the suffix S45. On the 208-240 V and 380-500 V models, output current ratings are reduced by 10% on mains supply voltages over 460 V; Siemens does not print that reduction against the 525-575 V models, whose output current is stated at 575 V.
