■ V/f Pattern Settings E1-04 to E1-13
If E1-03 is set to a preset V/f pattern (i.e., set to any value besides F), then the user can refer to parameters E1-04 through
E1-13 to monitor the V/f pattern. To create a new V/f pattern, set E1-03 to F. Refer to
V/f pattern.
Note: Certain E1- parameters might not be visible depending on the selected control mode.

<1> Default setting is determined by the control mode.
<2> When using PM motors, 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> The drive changes these settings when Auto-Tuning is performed (Rotational Auto-Tuning, Stationary Auto-Tuning 1, 2).
<5> Parameter ignored when E1-11 and E1-12 are set to 0.0.
<6> The default value shown here is for the following localized drives: Japan (Model code: CIMR-AA A), Asia (Model code: CIMR-AT A).
For default value of China localized drive (Model code: CIMR-AB A), refer to the A1000 Technical Manual.

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 = E1-07. In this case the E1-08 setting is disregarded.
3. E1-03 is unaffected when the parameters are initialized using parameter A1-03, but the settings for E1-04 through E1-13 are returned
to their default values.
Parameters E1-11, E1-12, and E1-13 should only be used to fine-tune the V/f pattern in the constant output range.
These parameters rarely need to be changed.
E2-01: Motor Rated Current
■
Set E2-01 to the full load amps (FLA) stamped on the motor nameplate. This value is used for motor protection and to
calculate torque limits. If Auto-Tuning completes successfully, the value entered to T1-04 will automatically be saved to
E2-01.
No.
E2-01
Note: This value's number of decimal places depends on the drive model and the Heavy/Normal duty selection in parameter C6-01.
The value will have two decimal places (0.01 A) if the drive is set for a Maximum Applicable Motor Capacity up to 11 kW (refer
to Table 60 and Table
Note: If the motor rated current in E2-01 is set lower than the motor no-load current in E2-03, than a parameter setting error will occur
(oPE02). E2-03 must be set correctly to prevent this error.
