Motor ovld fac-

(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
Motor ovld time
(PAR 3204). After the set time, the MOTOR
OVERLOAD function automatically sets the torque current limit so that Iout max. does not exceed
Rated cur-
rent

Motor service factor
(PAR 3206).
If the value of parameter 3202
Motor ovld factor
is 100 % the overload current of the Motor Overload func-
tion is equal to the continuous current of the Motor Overload function. In this case the drive behaves as if the
overload cycle has been executed and so sets the torque current limit so that Iout max is not more than the
continuous current, i.e.
Rated current

Motor ovld factor
(PAR 3202) is supplied to the motor for the time set in
Motor
ovld time
(PAR 3204).
The MOTOR OVERLOAD protection intervention time depends on the level of current circulating in the mo-
tor, a current equal to the overload level is allowed for the time set in
Motor ovld time
a current at below the
overload level is allowed for longer.
This alarm can be assigned to a programmable digital output (
Motor overload trip
).
The trip time depends on the motor current value, see figure on previous page.

Servo fan
Auto fan
indicates 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.
Servo fan
indicates the presence of an independent fan unit that therefore always runs at the rated speed. It en-
sures optimum cooling efficiency at all motor speeds.
When the current motor speed is below (PAR 2004
Rated speed
/ 2) and PAR 3216
Motor fan type
= Auto fan; ,
the MOTOR OVERLOAD protection intervention time must be reduced as cooling is insufficient.
At below (PAR 2004
Rated speed
/ 2) the protection intervention time is reduced by reducing the direct current of
the MOTOR OVERLOAD function.
