Service
BONFIGLIOLI recommends regular maintenance of the frequency inverter. Service periods depend on
the field of application and the ambient conditions.
Test/inspection and measure
heat sink
• Remove any soiling and dust.
• Check screws for tight fit, tighten if necessary.
• Check component for damage and replace, if necessary.
• Remove any soiling and dust.
• Check for unusual operating noise.
Door filter in electrical
cabinet
• Clean or replace.
• Check if ambient conditions meet specifications. See chapter 11.2
"Device data".
• Check if frequency inverter or motor emits excessive heat or if compo-
nents change their color. In this cases:
− Check for overload.
− Check heat sink and motor for soiling.
− Check ambient temperature.
• Check cable connections for safe connection.
• Check cables for damage, color changes and heat impact.
• Check cable insulation and shields for wear and tear.
• Replace damaged cables.
• Check for color changes and heat impact. Check connection.
Test run after service
Check the frequency inverter in a test run (if possible).
environment
Display error via operator panel or PC software VPlus. Eliminate cause of
error and acknowledge error.
See chapter 13.1 „Error list".
Measure mains voltage. Note rated values on the rating plate of the fre-
quency inverter.
Measure voltage of external DC 24 V supply (if installed). Specification: See
chapter 5.7.6 "External DC 24 V power supply".
Measure output current. Check the drive system and the load behavior if
the output current is greater than the nominal value of the frequency in-
verter over extended periods.
Vibration or unusual
noise of motor
Check the coupled load. Fix loose components.
