22.5.2 3202Motorovldfactor perc FLOAT 150.0 100.0 300.0 ERWS FVS
Setting of the motor overload value. The value is expressed as a percentage of Ratedcurrent (PAR 2002) *
Motorservicefactor (PAR 3206).
The current obtained from Ratedcurrent (PAR 2002) * Motorservicefactor (PAR 3206) * Motorovldfactor
(PAR 3202) is the maximum current that can circulate in the motor.
If the MOTOR OVERLOAD function is enabled the drive automatically sets the torque current limit so that Iout
max. does not exceed this value. The MOTOR OVERLOAD function can be used to deliver current to the motor
at the overload value for a time set in Motorovldtime (PAR 3204). After the set time, the MOTOR OVER-
LOAD function automatically sets the torque current limit so that Iout max. does not exceed Ratedcurrent
(PAR 2002) * Motorservicefactor(PAR 3206).
If the value of parameter 3202 Motorovldfactor is 100 % the overload current of the Motor Overload function
is equal to the continuous current of the Motor Overload function. In this case the drive behaves as if the over-
load cycle has been executed and so sets the torque current limit so that Iout max is not more than the continu-
ous current, i.e. Ratedcurrent (PAR 2002) * Motorservicefactor(PAR 3206).

22.5.3 3204Motorovldtime s FLOAT 30.0 10.0 300.0 ERWS FVS
Setting of the motor overload duration in seconds.
With the MOTOR OVERLOAD function a current equal to the level of Ratedcurrent (PAR 2002) * Motorserv-
icefactor (PAR 3206) * Motorovldfactor(PAR 3202) is supplied to the motor for the time set in Motorovld
time (PAR 3204).
The MOTOR OVERLOAD protection intervention time depends on the level of current circulating in the motor, a
current equal to the overload level is allowed for the time set in Motorovldtime a current at below the over-
load level is allowed for longer.
This alarm can be assigned to a programmable digital output (Motoroverloadtrip).
The trip time depends on the motor current value, see gure on previous page.

22.5.5 3216Motorfantype ENUM Servo fan 0 1 ERW F_S
This parameter is used to set the type of motor cooling system.
0 Auto fan
1 Servo fan
Autofanindicates the presence of a fan unit mounted on the motor shaft that therefore turns at a speed propor-
tional to the motor speed. Cooling is not very effective at low motor speeds.
Servofanindicates the presence of an independent fan unit that therefore always runs at the rated speed. It en-
sures optimum cooling efciency at all motor speeds.
When the current motor speed is below (PAR 2004 Ratedspeed / 2) and PAR 3216 Motorfantype = Auto fan; ,
the MOTOR OVERLOAD protection intervention time must be reduced as cooling is insufcient.
At below (PAR 2004 Ratedspeed / 2) the protection intervention time is reduced by reducing the direct current of
the MOTOR OVERLOAD function.
