The maximum torque current I
sq max
(>19.8<) results from the max. drive current I
max aux
with subtraction 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–.
m Load factor mode ASM-IsdMax 
ASM only: Z138.1– bit 1 = 1 (bit 3 = 0 from FW 01.13 of the controller): 
I
max aux
= "Max. drive current actual value" Z19.5–
I
sd aux
= "Limit magnetizing current" Z146.13–. 
m Current mode (from controller FW 01.13 onwards) 
Z138.1– bit 3 = 1 (independent of bit 1 and the motor type)
I
max aux
= "Max. drive current" Z19.6–
I
sd aux
= 0,
or I
sq max ref
* >19.8< = "Max. drive current" Z19.6–
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–.
