Elevator mode
● When "5" or "6" is set in Pr. 292 "Automatic acceleration/deceleration", elevator mode is
selected and each setting is changed as in the table below.
● Enough torque is generated during power driving and the torque boost value is automatically
changed during regeneration and operation without load (refer to Fig. 6-63) so that
overcurrent protection function does not activate due to over excitation.
