Menus 324 and [325] to set thebrake time and strength.6.5 Special conditions6.5.1 Small motor or low loadThe minimum load current for the MSF 2.0 softstarter is10% of the rated current of the softstarter, except for theMSF-017 where the min. current is 2 A. Example: MSF-210, rated current = 210 A. Min. Current 21 A. Please notethat this is “minimum load current” and not minimum ratedmotor current.6.5.2 Ambient temperature below0°CFor ambient temperatures below 0°C an electric heater orsimilar must be installed in the cabinet. The softstarter canalso be mounted somewhere else since the distance betweenthe motor and the softstarter is not critical.6.5.3 Phase compensation capacitorIf a phase compensation capacitor is to be used, it must beconnected at the inlet of the softstarter, not between themotor and the softstarter.6.5.4 Shielded motor cableIt is not necessary to use shielded wires together with softstarters.This is due to the very low radiated emissions.NOTE! The softstarter should be wired with a shieldedcontrol cable to fulfil the EMC regulations outlinedsection 1.6, page 6.6.5.5 Pump control with softstarterand frequency invertertogetherIt is possible, e.g. in a pump station with two or morepumps, to use one frequency inverter on one pump and softstarterson each of the other pumps. The flow of the pumpscan then be controlled by one common control unit.6.5.6 Starting with counterclockwiserotating loadsIt is possible to start a motor clockwise, even if the load andmotor are rotating counterclockwise e.g. fans. Depending onthe speed and the load “in the wrong direction” the currentcan be very high.6.5.7 Running motors connected inparallelWhen starting and running motors connected in parallel,the total amount of the motor current must be equal orlower than the rating of the connected softstarter. Pleasenote that it is not possible to have individual settings foreach motor or to use the internal thermal motor protection.The start ramp can only be set for an average starting rampfor all the connected motors. This means that the start timemay differ from motor to motor.For motors connected in parallel, torque control is not recommendedbecause of the risk of oscillation between themotors. Voltage control with or without current limit is preferredinstead. The use of the braking functionality is notrecommended for motors connected in parallel.36 Applications and functions selection Emotron AB 01-4135-01r2
