Description
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 16 mA.
Example: Inverter normal current (11 kW) is 24 A. 160% = 38.4 A.
Motor normal current is 22 A, the readout is 13.17 mA.
If the normal motor current is equal to 20 mA, the output setting
of parameter 6-52 Terminal 42 Output Max Scale is:
The torque setting is related to the setting in parameter 4-16
Torque Limit Motor Mode.
The torque setting is related to the motor torque setting.
Taken from parameter 1-20 Motor Power [kW].
Taken from parameter 3-03 Maximum Reference. 20 mA = value
in parameter 3-03 Maximum Reference.
Torque reference related to 160% torque.
An output value set from fieldbus process data. The output works
independently of internal functions in the drive.
An output value set from fieldbus process data. The output works
independently of internal functions in the drive.
Parameter 4-54 Warning Reference Low defines the behavior of
the analog output in case of fieldbus timeout.
Parameter 4-54 Warning Reference Low defines the behavior of
the analog output in case of fieldbus timeout.
An output value based on main actual value from serial
communication.
An output value based on main actual value from serial
communication.
Analog output at 0 torque is 12 mA. Motoring torque increases
the output current to maximum torque limit 20 mA (set in
Parameter 4-16 Torque Limit Motor Mode). Generating torque
decreases the output to torque limit in generator mode (set
in parameter 4-17 Torque Limit Generator Mode) Example:
Parameter 4-16 Torque Limit Motor Mode = 200% and parameter
4-17 Torque Limit Generator Mode = 200%. 20 mA = 200%
motoring and 4 mA = 200% generating.
