  • Page 57: Soft Start Methods

    Constant current is the traditional form of soft starting, which raises the current from 0 to a specified level and keeps the current stable at that level until the motor has accelerated. Constant current starting is ideal for applications where the start current must be kept below a particular level. Danfoss A/S © 2018.10 AQ262141844215en-000202 / 175R1174 | 57...

  • Page 58: Constant Current With Current Ramp

    The load breaks away easily, but starting time has to be extended (for example a centrifugal pump where pipeline pressure has to build up slowly). • The electricity supply is limited (for example a generator set), and a slower application of load allows greater time for the supply to respond. 58 | Danfoss A/S © 2018.10 AQ262141844215en-000202 / 175R1174...

    During braking, an increased noise level from the motor may be audible. This is a normal part of motor braking.
