When no signal on the analog output.
0hz = 0mA; 100hz = 20mA.

100% = 20mA
3-00 Reference Range [-Max - Max] -100% =
0mA; 0% = 10mA; +100% = 20 mA
Value is taken from 16-37 Inv. Max. Current.
Inverter max. current (160% current) is equal
to 20mA.
Example: Inverter norm current (15 hp [11
kW]) = 24 A. 160% = 38.4 A. Motor norm
current = 22 A Readout 11.46mA.
