0 : [Disabled]
1 : [No Derating]
2 : [Forced Cooling]
3: [Fan on Shaft]
Default
1
1 : [No Derating]
Level
BASIC
Address
1265
Function
This parameter enables the Motor Thermal Protection function.
It also selects the type of thermal protection among different trip patterns.
C266
Pick-Up Current for Motor 1
Range
1
min [120; [((Imax/Imot)*100) ].
1
min [120%; [((Imax/Imot)*100) %].
Default
105
105%
Level
ADVANCED
Address
1266
Function
This parameter sets the thermal protection trip current expressed as a percentage of the motor rated
current.
C267
Thermal Time Constant for Motor 1
Range
1
10800
1
10.800s
Default
720
720s (corresponding to Class IEC 20)
Level
BASIC
Address
1267
Function
This parameter sets the thermal time constant of the connected motor. The time constant is the time
within which the calculated thermal stage has reached 63% of its final value.
The motor attains its thermal time constant when it operates in constant load conditions for a time
equal to approx. 5 times the constant set in this parameter.
C274
PTC Thermal Protection Enable
Range
0 ÷ 1
0: Disabled
1: Enabled
Default
0
Disabled
Level
ADVANCED
Address
1274
Function
This parameter enables the PTC probe (AIN2 analog input)
