<1>
<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.
The following tables show details on predefined V/f patterns.
Predefined V/f Patterns for Models 2A0004 to 2A0021, 4A0002 to 4A0011, and 5A0003 to 5A0009
The values in the following graphs are specific to 200 V class drives. Double the values for 400 V class drives. Multiply the
values by 2.875 for 600 V drives.

YASKAWA SIEP YAIP1U 01C AC Drive - P1000 Technical Manual
Application
For general purpose applications. Torque remains
constant regardless of changes to speed.
For fans, pumps, and other applications where the
required torque changes as a function of the speed.
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.
Output voltage is constant when operating at greater than
60 Hz.
For general purpose applications. Torque remains
constant regardless of changes to speed.
