Caution:
When the V/F control mode selection is set to : Automatic torque boost control, : Vector control,
: Energy-saving, : Dynamic energy-saving, or : PM motor control, be sure to set the following
parameters according to the motor's name plate.
: Base frequency 1 (rated frequency)
: Base frequency voltage 1 (rated voltage)
: Motor rated capacity
: Motor rated current
: Motor rated speed
Set the other motor constants as necessary
1) Constant torque characteristics
Setting of V/F control mode selection to (V/F constant)
This is applied to loads with equipment like conveyors and cranes that require the same torque at low
speeds as at rated speeds.
