Fig. 6.7.8.b Tripping times for F5-B, F5-G and F5-M
For self-ventilated motors the
tripping times decrease with the
frequency of the motor (see picture).
The motor protective function acts in-
tegrating, i.e. times with overload on
the motor are added, times with
underload are substracted. After
triggering the motor protective
function, the new tripping time is
reduced to 1/4 of the specified value,
if the motor has not been operated
for an appropriate time with
underload.
Motor protection / rated
current (dr.12)
This parameter specifies for each set the rated current (= 100% utilization) for the
motor protective function. The motor protection-load is calculated as follows:
Inverter Apparent current(ru.15)
Motor protection-load =
Motor protection rated current (dr.12)
The cooling mode of the motor is adjusted with these programmable parameters.

1 Self-cooling

(dr.11)
OH2 stopping mode (Pn.14)
This parameter determines the behaviour of the drive when the motor protective
function responses. The function is described in Chapter 6.7.6.
