I have a 460 volt motor with a Danfoss 2800 Frequency drive for a conveyor, the conveyor will stop unexpectly and restart. The speed is set at 38 percent which drops the voltage at the motor to 280 volts. The parameters in the drive are set at the motor nameplate 1/2 hp. The question is do I have to change the parameters of the drive to match a 240 volt feed. Or what else would cause a conveyor to start and stop on its own.
