3.8.11 Operating mode current control
At the current control operating mode (
Z
109.1
–
= -2) either the torque current set value
or a torque set value (as of FW version 1.14 and if
Z
18.9
–
bit 5 = 1) can be specified. In
this case the speed controller output has no effects.
The set field current is determined by the field weakening controller or from the flux con-
troller.
The torque current and the field current are controlled in the d-q-current controller.
The torque current set value can be written to the writable parameter "isq set value for
OM current control (
Z
18.50
–
) in % (standardization: 100%= I
sq max
Z
19.8

)
The torque set value can be written in the writable parameter "Torque set value for OM
current control" (
Z
18.78
–
) in % (standardization: 100% = M
base
Z
138.34

).
At the torque current specification (
Z
18.9
–
bit 5 = 0) the torque current set value in A is
converted. At the torque specification (
Z
18.9
–
bit 5 = 1) the torque set value at first is re-
scaled and then is converted with the current Kt factor (Kt-factor

factor
Z

) and the flux set value
Z

–
into a torque current in A. Then, the
result (torque current set value in A) is passed on to the motor manager in RT0 cycle (lsq
set value unlimited
Z
18.45
–
).
Furthermore, additional torque current
Z

–
can be added to the lsq set value unlimit-
ed. The result is checked upon limits and is transferred to the current controller (lsq set
value

).
