URRENT
The current can be set to 0.0…2*I
L
. For a stall stage to occur, the current must have exceeded
this limit. See Figure 47. If parameter P3.1.3.1
Current Limit
is changed, this parameter is au-
tomatically calculated to 90% of the current limit.
NOTE! In order to guarantee desired operation, this limit must be set below the current limit.

IMIT
This time can be set between 1.0 and 120.0s.
This is the maximum time allowed for a stall stage. The stall time is counted by an internal up/
down counter.
If the stall time counter value goes above this limit the protection will cause a trip (see
P3.9.3.1).
P3.9.4.2 F
IELDWEAK
. L
OAD
The torque limit can be set between 10.0-150.0 % x T
nMotor
.
This parameter gives the value for the minimum torque allowed when the output frequency is
above the field weakening point. See Figure 48.
If you change parameter P3.1.1.4 (
Motor Nom Currnt
) this parameter is automatically restored
to the default value.
