5.5 E: Motor Parameters
5.5 E: Motor Parameters
E parameters cover V/f pattern and motor data settings.
◆
E1: V/f Pattern for Motor 1
■
V/f Pattern Settings (E1-03)
The drive uses the V/f pattern that has been set to adjust the output voltage relative to the frequency reference. There are
15 different preset V/f patterns (setting 0 to E) to select from, each with varying voltage profiles, saturation levels
(frequency at which maximum voltage is reached), and maximum frequencies. Additionally, one custom V/f pattern is
available (setting F). The custom V/f pattern requires the user to create the pattern using parameters E1-04 through
E1-10.
■
E1-03: V/f Pattern Selection
The user can select the V/f pattern for the drive and motor from 15 predefined patterns, or create a custom V/f pattern.
Setting a Predefined V/f Pattern (Setting 0 to E)
Choose the V/f pattern that best meets the application demands from
. These settings are available only in V/f
Control modes. Set the correct value to E1-03. Parameters E1-04 to E1-13 can only be monitored, not changed.
Note: 1.
Setting an improper V/f pattern may result in low motor torque or increased current due to overexcitation.
2.
Parameter E1-03 is not reset when the drive is initialized.

<1> Setting F enables a custom V/f pattern by changing parameters E1-04 to E1-13. When the drive is shipped, the default values for parameters
E1-04 to E1-13 are the same as those of setting 1.
