Output Voltage (V)Frequency (Hz)E1-05E1-12E1-13E1-08E1-10E1-09 E1-07 E1-06 E1-11 E1-04Figure 1.50 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. Performing Auto-Tuning (including Rotational Auto-Tuningand Stationary Auto-Tuning 1 and 2) automatically sets these parameters. Refer to Auto-Tuning Fault Detection on page217 for details if Auto-Tuning cannot be performed.Note: The function for switching between two motors cannot be used with a PM motor. E2-oo parameters are hidden when a PM motor controlmode is selected (A1-02 = 5, 6, or 7).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. If Auto-Tuning completes successfully, the value entered to T1-04 will automatically be saved to E2-01.No. Parameter Name Setting Range DefaultE2-01 Motor Rated Current 10% to 200% of the driverated currentDetermined byC6-01 and o2-04Note: 1. The number of decimal places in the parameter value depends on the drive model and the ND/HD selection in parameter C6-01. Thisvalue has two decimal places (0.01 A) if the drive is set for a maximum applicable motor capacity up to and including 11 kW, and onedecimal place (0.1 A) if the maximum applicable motor capacity is higher than 11 kW.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. This value isautomatically set during Auto-Tuning (Rotational Auto-Tuning, Stationary Auto-Tuning 1 and 2).No. Parameter Name Setting Range DefaultE2-02 Motor Rated Slip 0.00 to 20.00 Hz Determined byC6-01 and o2-04If 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.
