⋅ 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 so that overcurrent protection function does not activate due to over

excitation.

⋅ When operating the elevator with load more than the rated inverter current, the maximum torque may become

insufficient. For the elevator without counterweight, setting "2 or 3" (for elevator load) in Pr. 14 Load pattern selection

and an appropriate value in Pr. 19 Base frequency voltage  will generate larger maximum torque than when elevator

mode is selected.

⋅ By setting the adjustment parameters Pr. 61 and Pr. 64, the application range can be made wider.

Operation matching a load characteristic of elevator with counterweight can be performed.

⋅ Stall prevention operation level automatically decreases according to the electronic thermal relay function cumulative value, to

⋅ Even if elevator mode has been selected, inputting the jog signal (jog operation), RT signal (second function selection) or X9

signal (third function selection) during an inverter stop will switch to the normal operation and give priority to jog operation or

second and third function selection. Note that JOG and RT signal input is invalid even if JOG signal and RT signal are input

during operation with acceleration/deceleration selected.

⋅ Elevator mode is invalid when Advanced magnetic flux vector, Real sensorless vector control or vector control is selected.

⋅ Since the Pr. 61 and Pr. 64 settings automatically return to the initial value (9999) if the Pr. 292 setting is changed, set Pr. 292 first

when you need to set Pr. 61 and Pr. 64.
