V/f Pattern Selection: E1-03

Parameter E1-03 is only available when using V/f Control. It allows the user to set the
required V/f pattern and drive output voltage. When running a high-speed or special-purpose
motor, this function fine tunes the amount of torque required for the load. Select the V/f
pattern from 15 fixed V/f patterns or 1 user-programmable V/f pattern.

Setting Instructions for Setting a V/f Pattern

■
1.
Set the input voltage for the drive.
page 138.
2.
Select one of the two following V/f patterns:
• *Select one of the 15 preset V/f patterns (setting = 0 through E)
• **Select the Custom V/f pattern (setting = F)
3.
In case of * the following parameters are automatically set.
In case of **, the following parameters are adjustable.
E1-04 (Max Output Frequency), E1-05 (Max Voltage), E1-06 (Base Frequency), E1-
07 (Mid Output Frequency), E1-08 (Mid Output Frequency Voltage), E1-09 (Min
Output Frequency), E1-10 (Min Output Frequency Voltage)

Selecting a Preset V/f Pattern

■
There are two types of V/f patterns: a method to select one of the 15 presets (set value: 0 to
E) and a method to select arbitraty V/f pattern (set value: F). Refer to

Description
0 to E: Select from 15 preset V/f patterns.
F: Custom V/f pattern (allows use of E1-04 through E1-10).
