Using V/f Control Mode
Vector control mode is preset at the factory.
Control mode selection (n002): 0: V/f control mode (initial setting)
1: Vector control mode
Adjust motor torque by using “V/f pattern” and “full-range automatic torque boost”.
• V/f pattern setting
Set V/f pattern by n011 to n017 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 n011
to n017.
n016 <
n014 < n013 < n011
If n016 = n014 is set, the set
value of n015 is disabled.
