Possible cause or remedy
Fan motor has excessive temperature in the winding
•
a) One phase is missing from the power connection
b) Fan motor is defective
c) One phase is not connected through from the
contactor
d) Microfuse F10 (6.3 A or 10 A for floor models)
has tripped
e) Thermoprotection contact in the motor winding
(bi-metallic strip) defective or interrupted
Replace the converter
•
Check the environment (electro magnetic
•
compatibility)
Replace the converter
•
Braking or driving load too strong
•
Moment of inertia too high or load too strong.
•
Check the motor /converter dimensioning / check
load
Mechanical blockage, check the mechanics
•
Check the motor load, converter and environment
•
ventilation. Wait for it to cool down before switching
on again.
Current strength above overload threshold value
•
Check mechanics (wear and tear, mechanical
•
steering heaviness, lubrication, obstructions,...)
Check the thermoprotection settings for the motor
•
and motor overload. Wait for it to cool down before
switching on again.
Check the mains voltage
•
Check connection cable between converter and
•
motor and the motor insulation
Check the mains voltage
•
