Time Chart
The following figure shows the output frequency characteristics when L3-01 is set to 1.

Setting Precautions
• Set the parameters as a percentage taking the inverter rated current to be 100%.
• Do not increase the stall prevention level unnecessarily. An extremely high setting can reduce the inverter
lifetime. Also do not disable the function.
• If the motor stalls with the factory settings check the V/f pattern settings (E1-) and the motor setup
(E2-).
• If the stall level has to be increased very much to get the elevator running, consider to use a one size bigger
inverter.
