INVERTER SF-2 Series SensorlessVector Inverter CW No. D5E-2. No. D5E-2
The SF-2 series, designed for the global market adds new, more powerful vector control to standard V/f control. Easy-To-Use,Powerful Inverter Powerful drive A new vector control mode is added to the default V/f control mode to insure proper starting of a gearmotor in difficult applications. [ Starting torque of AF motor :75 to 2% of motor full-load torque] Global standards The standard unit complies with international requirements (UL, CSA, CE marking) The I-O control logic can also switch between sinking and sourcing. Easy to Operate and Easy to Setup Local operator control is provided by the frequency potentiometer and the drive Run and Stop keys. Wizard functions simplify parameter setting. Easy Wire and Install Panel wiring is simplified because of the location of input power and load terminals in a contactor type (top and bottom) arrangement. Self-lifting screw terminals make wiring the drive an easy task.
