Program features 79
The figure below shows typical PTC sensor resistance values as a function of the
motor operating temperature.
It is possible to adjust the motor temperature supervision limits and select how the
drive reacts when overtemperature is detected.
For further information on the wiring, refer to the Hardware Manual of the drive.
Settings
Parameter group 31 Motor therm prot (page 197).
Diagnostics
Parameters 01.17 Motor temp1 (page 112) and 01.18 Motor temp2 (page 112).
Programmable protection functions
Start interlock (parameter 10.20)
The parameter selects how the drive reacts to loss of start interlock signal (DIIL).
External fault (parameter 30.01)
A source for an external fault signal is selected by this parameter. When the signal is
lost, a fault is generated.
Local control loss detection (parameter 30.03)
The parameter selects how the drive reacts to a control panel or PC tool
communication break.
Motor phase loss detection (parameter 30.04)
The parameter selects how the drive reacts whenever a motor phase loss is detected.
