■ V/f Pattern Settings E1-04 to E1-13
Using parameters E1-04 through E1-13, the user can either monitor the V/f pattern values if set up a custom V/f pattern
as shown in Figure 5.33.
Figure 5. 33
Figure 5.33 V/f Pattern
Note: 1. The following condition must be true when setting up the V/f pattern: E1-09 ≤ E1-07 ≤ E1-06 ≤ E1-11 ≤ E1-04
2. To make the V/f pattern a straight line set E1-09 = E1-07. In this case the E1-08 setting is disregarded.
◆ E2: Motor 1 Parameters
These parameters contain the most important motor data needed for optimal motor control. They are set automatically
when Auto-Tuning is performed. If Auto-Tuning can not be performed, then these parameters can be set manually.
■
E2-01: Motor Rated Current
Set E2-01 to the full load amps (FLA) stamped on the motor nameplate. During Auto-Tuning the value must be entered
to parameter T1-04. If Auto-Tuning completes successfully, the value entered will automatically be saved to E2-01.
Note: 1. Setting units vary by the maximum allowable motor capacity, which is determined by C6-01 and o2-04. Drives up to 11 kW display a
two-digit value, while drives 11 kW and larger display a single-digit value.
2. Change E2-01 only after changing the value set to E2-03. If E2-01< E2-03, then parameter setting error oPE02 will occur.
No.
<1> Default setting depends on the control mode selection in parameter A1-02. The value shown here is for V/f Control. Refer to Control Mode
Dependent Parameter Default Values on page 364.
<2> When using OLV/PM control mode, the default setting is determined by the motor code set to E5-01.
<3> Values shown here are for 200 V class drives. Double values when using a 400 V class unit.
<4> When E1-13 = 0.0 V, the drive uses the value set in E1-05 to control the voltage.
