Motor cur. 4–
20mA
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.
16 mA × 22 A
38.4 A
= 13 . 17 mA
If the normal motor current is equal to 20 mA, the output setting of

Bus ctrl.
An output value set from fieldbus process data. The output works independently of internal func-
tions in the drive.

tions in the drive.
[141]
Bus ctrl t.o.
Parameter 4-54 Warning Reference Low
defines the behavior of the analog output in case of fieldbus
timeout.

Torque % lim
4-20mA
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 Genera-
tor Mode
= 200%. 20 mA = 200% motoring and 4 mA = 200% generating.
