5.7Maximum frequency

HJ: Maximum frequency

Function

1)Programs the range of frequencies output by the inverter (maximum output values).

2)This frequency is used as the reference for acceleration/deceleration time.

Output frequency

When HJ=80Hz

 

(Hz)

This function determines the value

80Hz

 

 

in line with the ratings of the motor

 

 

 

and load.

60Hz

When HJ=60Hz

Maximum frequency cannot be

 

 

 

adjusted during operation.To

 

 

 

adjust, first stop the inverter.

5.8Upper limit and lower limit frequencies

WN: Upper limit frequency

NN: Lower limit frequency

Function

Programs the lower limit frequency that determines the lower limit of the output frequency and the upper limit frequency that determines the upper limit of that frequency.
