Maximum
Operating
frequency
To protect the motor load, maximum operating
frequency must be same as rated frequency of
motor.
Associated with the output V/F curve
0.01-60.00
50.00Hz

Weak light
frequency
0-60.00
Once the output frequency is less than the set
value and continuously lasts for a period (set value
of Pr.25), the inverter will enter weak light
protection and report as too dark.

Others:
Other value settings are forbidden, or
else can cause abnormal operation
Note:
11&I2, I3&I4 are group terminals,
support linkage use or separate use.
When Pr.15 or Pr.17 is set to 8 or 9, Pr.16 or
Pr.18 value setting will be invalid.
