[100] Output frequency 0-20 mA 0 Hz = 0 mA; 100 Hz = 20 mA.
[101] Reference 0-20 mA Par. 3-00 [Min - Max] 0% = 0 mA; 100% = 20 mA
Par. 3-00 [-Max - Max] -100% = 0 mA; 0% = 10 mA; +100% = 20 mA
[102] Feedback
[103] Motor current 0-20 mA Value is taken from par. 16-37. Inverter max. current (160% current) is equal to 20 mA.
Example: Inverter norm current (11 kW) = 24 A. 160 % = 38.4 A. Motor norm current = 22 A Read-
out 11.46 mA.
