When the set frequency is greater than the
heavy load speed-limit detection frequency
(P91.14), the motor
becomes stable after reaching the detection
frequency (P91.14), and load detection is
performed after the time specified by P91.15.
The load detection value is used for heavy load
speed limit calculation. The load detection
value P94.01 can be viewed through the
keypad.
Setting range of P91.14: 0.00Hz–P02.02
Setting range of P91.15: 0.00–5.00s
Setting range of P94.01: 0.0% –150.0% (of the
motor rated torque)
