Chapter 6 - Parameter Description [FU2]
6-34
Note: It is possible to occur No Motor Trip in case that the
torque boost value is 0 when DC Start is operated.
[Auto Torque Boost]
When FU2-67 [Manual/Auto torque boost select] is
set to “Auto”, inverter outputs high starting torque by
automatic boosting according to the load
characteristic.
Note: Auto torque boost is only applied to the 1
st
motor.
Only Manual torque boost is available for the 2
nd
motor.
Note: Auto torque boost is not available when FU2-60
[Control Mode] is set to ‘Sensorless’.
Note: Conduct Auto tuning in FU2-61 [Auto tuning] first
to use Auto torque boost effectively.
[Constant Torque Loads: Conveyor, Moving Equip. etc.]
[Ascending and Descending Loads: Parking, Hoist etc.]
