Manually set motor parameters if Auto-Tuningcannot be performed. Refer to Auto-Tuning on page 91 for more information. Refer to E: Motor Parameters for a list of motor parameters E2-01 toE2-12.n Setting Motor Parameters ManuallyThe following table provides instructions on how to set motor parameters. Refer to the motor data sheet for the correct motor data.No. Parameter Name Setting MethodE2-01 Motor Rated Current Sets the motor nameplate full load current in amperes (A).E2-02 Motor Rated Slip Calculate and set the motor rated slip based on the rated speed described on the motor nameplate.Motor rated slip = Motor rated frequency [Hz] - Rated speed [r/min] x No. of motor poles / 120.E2-03 Motor No-Load Current Set motor no-load current at rated voltage and rated frequency.Contact the motor manufacturer to get the no-load current. This information is not usually written on the motor nameplate.The default no-load current is for a Yaskawa 4-pole motor.E2-04 Number of Motor Poles Displayed only when OLV control mode is selected. Set the number of motor poles described on the motor nameplate.4.6 Basic Drive Setup AdjustmentsYASKAWA ELECTRIC SIEP C710606 18A YASKAWA AC Drive – V1000 Technical Manual (Preliminary) 854 Start-Up Programming& Operation
