Lift operation (Pr. 292 = "5, 6")
● When Pr. 292 "Automatic acceleration/deceleration" is set to "5" or "6", the lift operation is selected,
and each setting is changed, as shown in the table below.
● During power driving, sufficient torque is generated, and during regenerative driving and during
driving with no load, the torque boost setting is adjusted automatically so as not to activate the
overcurrent protective function by overexcitation.
