1 Drive generates warning A783 Motor overload when
the motor is overloaded to the warning level, that is,
parameter
35.5 Motor overload level reaches value
88.0%.
Warning only
2 Drive generates warning A783 Motor overload when
the motor is overloaded to the warning level, that is,
parameter
35.5 Motor overload level reaches value
88.0%.
Drive trips on fault
7122 Motor overload when the motor
is overloaded to the fault level, that is, parameter 35.5
Motor overload level reaches value 100.0%.
Warning and fault
Class 20 / uint16 Defines the motor overload class to be used. The class
of protection is specified by the user as the time for
tripping at 7.2 times (IEC 60947-4-1) or 6 times (NEMA
ICS) the tripping level current.
See section
Motor overload protection (page 132) .
Motor overload class 35.57
0 Motor overload class 5. Class 5
1 Motor overload class 10. Class 10
2 Motor overload class 20. Class 20
3 Motor overload class 30. Class 30
4 Motor overload class 40. Class 40
0.0 % / real32 Shows the calculated temperature of the motor cable.
See section
Thermal protection of motor
cable (page 133) .
102% = overtemperature warning ( A480 Motor cable
overload )
106% = overtemperature fault ( 4000 Motor cable
overload )
This parameter is read-only.
Cable temperature 35.60
1 = 1 % / 10 = 1 % Calculated temperature of motor cable. 0.0 ... 200.0 %
10000.00 A / real32 Specifies the continuous current of the motor cable
for the thermal protection function in the control
program.
WARNING!
The value entered in this parameter must be
limited according to all factors affecting the
loadability of the cable, such as ambient
temperature, cabling arrangement, and
shrouding. Refer to the technical data from the
cable manufacturer.
Cable nominal
current 35.61
1 = 1 A / 100 = 1 A Continuous current-carrying capacity of motor cable. 0.00 ... 10000.00 A
