Motor, Nom
The torque setting is related to the setting in parameter 4-16 Torque Limit Motor Mode.
The torque is related to the motor torque setting.
Taken from parameter 1-20 Motor Power [kW].
Taken from parameter 3-03 Maximum Reference. 20 mA equals the value in parameter 3-03 Maxi-
mum Reference.
Torque reference related to 160% torque.
0 Hz = 0 mA, parameter 4-19 Max Output Frequency = 20 mA.
0 Hz = 4 mA, 100 Hz = 20 mA.
Parameter 3-00 Reference Range [Min-Max] 0% = 4 mA; 100% = 20 mA
Parameter 3-00 Reference Range [-Max-Max] -100% = 4 mA; 0% = 12 mA; +100% = 20 mA.
The value is taken from parameter 16-37 Inv. Max. Current. The inverter maximum current (160%
current) is equal to 20 mA. Example: Inverter normal current (11 kW) is 24 A. 160% = 38.4 A. Motor
normal current is 22 A, the readout is 11.46 mA.
16 mA × 22 A
= 13 . 17 mA
38 . 4 A
If the normal motor current is equal to 20 mA, the output setting of parameter 6-52 Terminal 42
Output Max Scale is:
