Pr. 272 "mid-speed setting minimum current"
Pr. 273 "current averaging range"
Pr. 274 "current averaging filter constant"
z
Used to set the current, averaging range, etc. required when "2" or "3" is set in Pr. 270 to select load torque
high-speed frequency control.

The lift with a light load or without
 a load is moved faster than the
lift with a load.
(The output frequency is increased.) 
<With high-speed frequency control>
<Without high-speed frequency control>
Whether there is a load or
not, the lift is moved vertically
at the same speed.
