• Selecting V/f pattern
Adjust motor torque by using “V/f pattern” and “full-range automatic torque boost”.
•
V/f pattern setting
Set V/f pattern by parameters 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.
Be sure to satisfy the following conditions for
the setting of n09 to n15.
n14 < n12 < n11 < n09
If n14 = n12, the set value of n13 is disabled.
