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 59. If parameter P3.1.3.1
Current Limit
is changed, this parameter is automatically
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 60.
If you change parameter P3.1.1.4 (
Motor Nom Currnt
) this parameter is automatically restored to
the default value.

Selection Description
0 Disabled, The estimated motor temperature rise is set to zero.
1
Constant, Sets the motor temperature rise estimate to a value which equals the parameter P3.9.2.7 Mot-
TempInitialAdjust value.
2
Last value, Sets the motor temperature rise estimate to a last saved motor temperature rise estimate
multiplied with the parameter P3.9.2.7 MotTempInitialAdjust value.
3
Real time clock, Similar to the last value mode, but the last saved motor temperature rise estimate is
affected by real time and the parameter P3.9.2.4 ThermTimeConst. This mode requires that a battery is
connected to the real time clock.
