9.8 Maximum Frequency
This parameter determines the maximum speed of the pump and at which output frequency
the HYDROVAR has its max. output voltage.
The standard setting is according to the nominal frequency of the connected motor.
MAX. FREQUENCY
50.0 Hz
Possible setting between 40 and 70 Hz
Attention:
Settings higher than 50 Hz may overload the motor!
Settings of 10% above nominal frequency cause a 33% higher power
consumption!

9.9 Minimum Frequency
MIN. FREQUENCY
0.0 Hz
Possible setting between 0Hz and Max. frequency
At operation below the right min. frequency the HYDROVAR works with the fast Ramps.
Attention:
The min. frequency depends on the selected pump type.
Especially for borehole applications the min. frequency must be set to ~30Hz.
