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 of the drive to function properly. Failure to comply could result in improper drive operation.

Note: The braking transistor operation levels are valid for the drive internal braking transistor. If an external CDBR braking chopper is used, refer to the instruction manual of that unit.
n V/f Pattern Settings
The drive utilizes a set V/f pattern to determine the appropriate output voltage level for each relative to the frequency reference.
There are 15 different preset V/f patterns to select from with varying voltage profiles, saturation levels (frequency at which maximum voltage is reached), and maximum frequencies. Additionally, one custom V/f pattern can be set up by programming parameters E1-04 through E1-10.
V/f Pattern Setup for V/f Control
1.
Set the input voltage for the drive.
Refer to E1-01: Input Voltage Setting on page 155 .
2.
Set the V/f pattern by: a) choosing one of the 15 preset V/f patterns (E1-03 = 0 to E).
b) select the custom V/f pattern (E1-03 = F, default setting).
3.
When using one of the 15 presets, E1-04 through E1-13 are automatically set. Refer to the description below.
For a custom V/f pattern, E1-04 through E1-13 must be adjusted manually.
Refer to V/f Pattern Settings E1-04 to
E1-13 on page 158
.
n E1-03: V/f Pattern Selection
This parameter can only be changed when the drive is operating in V/f Control. It allows the user to select the V/f pattern from
15 predefined patterns or to create a custom V/f pattern.

Setting the V/f Pattern
Choose the V/f pattern that meets the application demands from the table below. Set the correct value to E1-03. The V/f 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.

Application
For general purpose applications. Torque remains constant regardless of changes to speed.
For fans, pumps, and other applications that require torque derating relative to the load.
Select high starting torque when:
• Wiring between the drive and motor exceeds
150 m
• A large amount of starting torque is required
• An AC reactor is installed
When operating at greater than 60 Hz the output voltage will be constant.

Setting a Custom V/f Pattern
Setting parameter E1-03 to “F” allows to set up a custom V/f pattern by changing parameters E1-04 to E1-13.
When E1-03 is changed to “F”, the default values for parameters E1-04 to E1-13 will be equal to V/f pattern 1 of the predefined patterns.
n 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 E1-03 ≤ 15 or set up a custom V/
f pattern as shown in Figure 5.38
when E1-03 = F.

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.
Setting E1-11 to 0 disables both E1-11 and E1-12 and the above conditions do not apply.
3.
To make the V/f pattern a straight line set E1-09 = E1-07. In this case the E1-08 setting is disregarded.
4.
E1-03 is unaffected when the drive is initialized using parameter A1-03, but the settings for E1-04 through E1-13 are returned to their default values.
