Yaskawa AC Drive Z1000 AC Drive HVAC Fan - Manual (Page 63)

Setting Specification Characteristic Application
8 50 Hz, Mid starting torque
High starting torque
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.
9 50 Hz, High starting torque
A 60 Hz, Mid starting torque
B 60 Hz, High starting torque
C 90 Hz (with 60 Hz base)
Constant output
Output voltage is constant when operating at greater than
60 Hz.
D 120 Hz (with 60 Hz base)
E 180 Hz (with 60 Hz base)
F
<1>
60 Hz Variable torque
Used for variable torque applications. The default setting is
the same as V/f pattern Setting 7.
<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 equal to predefined V/f pattern 1.
The following tables show details on predefined V/f patterns.
Predefined V/f Patterns for Models 5A0003 to 5A0009
