Selecting V/f pattern

Adjusting torque according to application
Adjust motor torque by using "V/f pattern" and "full-range automatic torque
boost".
• V/f pattern setting
Set V/f pattern by n09 to n15 as described below. Set each pattern when
using a special motor (high-speed motor, etc.) or when requiring special
torque adjustment of machine.

n15.
n14 Ã n12 < n11 Ã n09
If n14 = n12 is set, the set value of n13
is disabled.
