Setting a Custom V/f Pattern (Setting F: Default)
Setting parameter E1-03 to F allows the user to set up a custom V/f pattern by changing parameters E1-04 to E1-13.
n V/f Pattern Settings E1-04 to E1-13
Set E1-03 ≤ E to monitor, but not change, the V/f pattern using parameters E1-04 to E1-13. To create a new V/f pattern, set
E1-03 to F. Refer to V/f Pattern on page 151
Note: Certain E1-oo parameters might not be visible depending on the control mode.

<1> Default setting is determined by E5-01 in OLV/PM. When E5-01 is set to FFFF the setting range for E1-04 and E1-06 is 10.0 to 400.0 Hz and the
setting range for E1-09 is 0.0 to 400.0 Hz.
<2> Default setting is determined by the control method, drive model, and drive duty rating.
<3> When using PM motors, the default setting is determined by the motor code set to E5-01.
<4> Values shown are specific to 200 V class drives. Double the value for 400 V class drives. Multiply the value by 2.875 for 600 V class drives.
<5> The drive changes these settings when Auto-Tuning is performed (Rotational Auto-Tuning, Stationary Auto-Tuning 1, 2).
<6> Parameter ignored when E1-11 and E1-12 are set to 0.0.
<7> E1-13 and E1-05 are set to the same value when Auto-Tuning is performed.
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 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.
n E2-01: Motor Rated Current
Provides motor control, protects the motor, and calculates torque limits. Set E2-01 to the full load amps (FLA) stamped on
the motor nameplate. If Auto-Tuning completes successfully, the value entered to T1-04 will automatically be saved to E2-01.
