19.7 Max. field current amplitude
Display of the maximum amplitude of the field current. The maximum field current for syn-
chronous motors is set via the absolute value of the field current preset value (Z19.9–).
The maximum field current for asynchronous motors is set via the limitation of flux con-
troller (Z146.12–).
The maximum field current amplitude is limited by the maximum total current of the drive
(
Z19.6–):
Max. field current amplitude [>19.7<]  0,95 * Max. drive current [Z19.6–]
19.8 Max. torque current
Display of the reference variable of the maximum torque current in A.
The maximum torque current I
sq max
(>19.8<) results from the max. drive current I
max aux
and the reduction of the field current I
sd aux
.
The max. drive current I
max aux
and the field current I
sd aux
are dependent of the motor
type and of the torque current standardized modes (parameter "Mode of Iq limit"
Z138.1–
Bit 1 and Bit 3). The following modes are available:
m Standard load factor mode 
SM or ASM with Z138.1– bit 1 = 0 (bit 3 = 0 from FW 01.13 of the controller): 
I
max aux
= "Max. drive current actual value" Z19.5–
I
sd aux
= "Isd set value" Z47.2–.
NOTE!
The amplitude of the field current can be reduced automatically e. g. by the PU over-
load monitoring or phase fail (see "Bit bar of external current limit" Z138.8– and "Ex-
ternal limiting max. field current amplitude" Z138.10–), without the parameter value
>19.7< being changed. The currently effective present limit of the field current is the
minimum value between "Max. field current amplitude" >19.7< and "External limiting
max. field current amplitude"
Z138.10–.
NOTE!
The "Max. torque current" >19.8< is the standardized factor of the standardized
torque current limits of the parameters
Z138.2–, Z138.3–, Z138.14– and
Z138.15–, of the standardized torque current set values Z18.50– and Z19.51– as
well as of the standardized total current limit Z120.12–.
