Description

Frequency converters are divided into three groups by purpose. General industrial ones include Commander S, Commander C200/C300 and Unidrive M400, high-performance ones Unidrive M600 and Unidrive M700, and high power is covered by Powerdrive MD Smart and S-PowerDrive. Separately there are servo drives and the DC drive Mentor MP, which also works in the digital static excitation system of generators. For geared motors, built-in Varmeca and Commander ID300 converters are offered, and Dyneo+ motors are supplied as matched pairs with the drive. The Digistart D5 soft starter is compact and has built-in protection of the motor and driven machine, multi-protocol fieldbus communication, compatibility with IE3 motors and a bypass to save energy. Service functions include a mobile app, simulation mode, timers and schedulers, event time stamps, emergency mode and a dedicated pump board.

How to choose

First decide whether speed control is needed. If the motor runs at constant speed and only the starting current has to be limited, the Digistart D5 of 24–1250 A with built-in bypass or 190–1220 A without it is enough, in V5 versions for 200–525 V and V7 for 380–690 V at 50–60 Hz. To regulate pump or fan output take the Commander C200/C300 or Unidrive M400, for dynamic machines the Unidrive M600/M700, for large installations the Powerdrive MD Smart. The D4 model is in the range, but its specifications are not published, so data is requested separately.

FAQ

What current are Digistart D5 soft starters made for?

From 24 to 1250 A in the version with a built-in bypass and from 190 to 1220 A without a bypass. The built-in bypass reduces heating in the cabinet after run-up.

What electronics supply does the Digistart D5 need?

The control is powered from 110–120 or 220–240 V AC or from 24 V, so the device is connected to the existing control circuit of the cabinet.

What protection rating does the Digistart D5 enclosure have?

IP00 or IP20, so the device is placed in a control cabinet rather than openly in the workshop.

Does this range include a drive for DC motors?

Yes, it is the Mentor MP. It is also used in the digital static excitation system of generators.
