Output Voltage (V)Frequency (Hz)E1-05E1-12E1-13E1-08E1-10E1-09 E1-07 E1-06 E1-11 E1-04Figure 1.29 V/f PatternNote: 1. The following condition must be true when setting up the V/f pattern: E1-09 ≤ E1-07 < E1-06 ≤ E1-11 ≤ E1-042. To make the V/f pattern a straight line below E1-06, set E1-09 equal to E1-07. In this case the E1-08 setting is disregarded.3. E1-03 is unaffected when the drive is initialized, but E1-04 through E1-13 return to their default values.4. Only use E1-11, E1-12, and E1-13 to fine-tune the V/f pattern in the constant output range. These parameters rarely need to be changed.u E2: Motor 1 ParametersThese parameters contain the motor data needed for motor 1. Enter the motor data into these parameters when Auto-Tuningcannot be performed.Note: The function for switching between two motors cannot be used with a PM motor. E2-oo parameters are hidden when OLV/PM controlmode is selected (A1-02 = 5).n E2-01: Motor Rated CurrentProvides motor control, protects the motor, and calculates torque limits. Set E2-01 to the full load amps (FLA) stamped onthe motor nameplate.No. Parameter Name Setting Range DefaultE2-01 Motor Rated Current 10% to 200% of the driverated currentDetermined byo2-04Note: 1. Display is in the following units: 5A0007 to 5A0017: 0.01 A units; 5A0022 to 5A0242: 0.1 A units.2. An oPE02 error will occur if the motor rated current in E2-01 is set lower than the motor no-load current in E2-03. Set E2-03 correctlyto prevent this error.n E2-02: Motor Rated SlipSets the motor rated slip in Hz to provide motor control, protect the motor, and calculate torque limits.No. Parameter Name Setting Range DefaultE2-02 Motor Rated Slip 0.00 to 20.00 Hz Determined byo2-04If Auto-Tuning cannot be performed, calculate the motor rated slip using the information written on the motor nameplate andthe formula below:E2-02 = f - (n × p)/120(f: rated frequency (Hz), n: rated motor speed (r/min), p: number of motor poles)n E2-03: Motor No-Load CurrentSet the no-load current for the motor in amperes when operating at the rated frequency and the no-load voltage. The drive setsE2-03 during the Auto-Tuning process (Rotational Auto-Tuning and Stationary Auto-Tuning 1, 2). The motor no-load currentlisted in the motor test report can also be entered to E2-03 manually. Contact the motor manufacturer to receive a copy of themotor test report.No. Parameter Name Setting Range DefaultE2-03 Motor No-Load Current 0 to [E2-01] Determined byo2-04Note: Display is in the following units: 5A0007 to 5A0017: 0.01 A units; 5A0022 to 5A0242: 0.1 A units.1.5 E: Motor Parameters66 YASKAWA SIEP YAIZ1U 03B YASKAWA AC Drive – Z1000 Programming Manual
