PARAMETERS
4.2.61 High-speed frequency control (Pr. 271 to Pr. 274)
Pr. 271 "high-speed setting maximum current"
Pr. 272 "mid-speed setting minimum current"
Pr. 273 "current averaging range"
Pr. 274 "current averaging filter constant"
zUsed 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.
<Wiring example>
• Sink logic
• Pr. 186 = 19

271 50% 0 to 200%
272 100% 0 to 200%
273 9999 0 to 400Hz, 9999
274 16 1 to 4000
(Note) When load torque high speed
frequency control is selected,
automatic restart after instantaneous
power failure function is invalid.
Note: The input signal terminal used depends on the Pr. 180 to Pr. 186 settings.

Pr. 4 "multi-seed setting (high speed)"
Pr. 5 "multi-seed setting (middle speed)"
Pr. 6 "multi-seed setting (low speed)"
Pr. 59 "remote setting function selection"
Pr. 180 to Pr. 186
(input terminal function selection)
Pr. 270 "stop-on-contact/load torque
high-speed control selection"
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.
