Config. Fault<br />
• error saving in EEPROM • cut the power supply to the <strong>drive</strong> and<br />
reset<br />
• internal fault<br />
• connector fault<br />
• check the connectors in the <strong>drive</strong><br />
• fault triggered by an external device • check the device which has caused the<br />
fault and reset<br />
• no <strong>speed</strong> feedback • check the connection and the mechanical<br />
coupling of the <strong>speed</strong> sensor<br />
• non-following of ramp<br />
• <strong>speed</strong> inverse to the reference<br />
• instability<br />
• driving load too high<br />
• check the <strong>speed</strong> feedback settings and<br />
the wiring<br />
• check the suitability of the settings for<br />
the load<br />
• check the size of the motor-<strong>drive</strong> and the<br />
possible need for a braking resistor<br />
• check the settings and the parameters<br />
• add a braking resistor<br />
check the size of the motor/<strong>drive</strong>/load<br />
• communication fault on the fieldbus • check the network connection to the<br />
<strong>drive</strong><br />
• check the time-out<br />
• communication fault between the option<br />
card and the control card<br />
Error probably caused when changing<br />
the card:<br />
• change of rating of the power card<br />
• change of the type of option card or<br />
installation of an option card if there<br />
was not one already and if the macroconfig<br />
is CUS<br />
• option card removed<br />
• inconsistent configuration saved<br />
Pressing ENT brings up the message:<br />
Fact.Set ENT/ESC<br />
• inconsistent configuration sent to <strong>drive</strong><br />
via serial link<br />
• check the connection of the option card<br />
to the control card<br />
• check the <strong>drive</strong> hardware configuration<br />
(power card, others)<br />
• cut the power supply to the <strong>drive</strong> then<br />
reset<br />
• save the configuration in a file in the<br />
terminal<br />
• press ENT to return to factory settings<br />
• check the configuration sent previously<br />
• send a consistent configuration<br />
