Limit Values
Maximum inner limit frequency
Upper limit frequency
Unit Hz
Setting range -
Factory setting 60.49
Important The parameter ‘FREQIL
Max
’ cannot be set. It is for display
purposes only.
Maximum inner limit frequency trip time
Time duration in which exceeding the upper
limit frequency is allowed. When the upper
limit frequency is exceeded longer than the
set time, the inverter stops supplying energy
to the grid.
The display switches between ‘FREQIL
Max
’
and ‘FREQTRIP
Max
’.

Setting range -
Factory setting 9 at 208 V / 240 V / 277 V grid voltage
Important The parameter ‘FREQTRIP
Max
’ cannot be set. It is for display
purposes only.

Setting range 57.00 - 60.48
Factory setting 59.31
Minimum inner limit frequency
Lower limit frequency
Minimum inner limit frequency trip time
Time duration in which going below the lower
limit frequency is allowed. When the system
goes below the lower limit frequency longer
than the set time, the inverter stops supplying
energy to the grid.
The display switches between ‘FREQIL
Min
’
and ‘FREQTRIP
Min
’.
