Example: If automatic setting mode of high-speed operation speed is used,
set f328 to 1 for F (forward command): Up
set f328 to 2 for R (reverse command): Up
Note: Light load output and Heavy load output conditions of output terminal functions are different
according to f328 setting.
1) f328 (Light-load high-speed operation selection) =0
Light load output (Function No. 106/107):
ON: The absolute value of the detected torque is under the absolute value of f335
(Switching load torque during power running)
Light load output (Function No. 164/165):
ON: The absolute value of the detected torque is under the absolute value of f335
(Switching load torque during power running)
Heavy load output (Function No. 108/109):
ON: The absolute value of the detected torque is the absolute value of f337 (Heavy-load
torque during constant power running) or more
Note) Function No. 106/107 and No.164/165 are same action when f328=0. Each action is
different when f328 setting is not 0.
