n E1-01: Input Voltage Setting
Adjusts the levels of some protective features of the drive (overvoltage, Stall Prevention, etc.). Set this parameter to the nominal
voltage of the AC power supply.
NOTICE: Set parameter E1-01 to match the input voltage of the drive. Drive input voltage (not motor voltage) must be set in E1-01 for the
protective features to function properly. Failure to set the correct drive input voltage will result in improper drive operation.
No. Parameter Name Setting Range Default
E1-01 Input Voltage Setting 445.6 to 733.1 V 661.3 V
E1-01 Related Values
The input voltage setting determines the overvoltage and undervoltage detection levels, the KEB function, and the overvoltage
suppression function.

n V/f Pattern Settings E1-04 to E1-13
If E1-03 is set to a preset V/f pattern (i.e., a value other than F), the user can monitor the V/f pattern in parameters E1-04
through E1-13. To create a new V/f pattern, set E1-03 to F. Refer to V/f Pattern on page 128 for an example custom V/f
pattern.
Note: Certain E1- parameters might not be visible depending on the control mode. Refer to Parameter List on page 261 for details.

Figure 4.22 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 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.
