Maximum 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.

This function determines the value
in line with the ratings of the motor
and load.
Maximum frequency cannot be
adjusted during operation.To
adjust, first stop the inverter.
