Timed OverCurrent Trip - results typically due to too much load (>100%) for too long of time Hardware Fault- Googe CTTG138 or click here CTTG138.
O Suspect AC Power Line disturbances o Possibly install an AC Input Line Choke o A small DB resistor may be required as Pressure Relief o Disconnect built in EMC filter the re-try oĬonsult or Google CTTG136 or click on -> Input Power Problems CTTG143.doc V1.5 1 To Earth 600v for 240vac units and 1200v for 460v units If this happens when motor not running but just powered up.
Google CTTN158 & CTTG151 or click for more info o Possible shorted motor or motor lead between drive and motor o Remove motor leads from drive and megger each free motor lead If this happens on power up- remove motor leads and re-try o Remove built in EMC filter the re-try-( Pull tab on SKA-D ) If this happens when you try to Stop or decelerate- o Set #6.01=0 for Coast Stop (if possible ) o Increase Pr4 ( double/triple ) and re-try o Turn on #2.06 and set #2.07=100 or more o Set Pr41= Fd o You may need a dynamic braking resistor OverVoltage occurred For a Fan or Pump App Google CTAN293 or click If this happens when you try to Stop or decelerate- o Increase Pr4 ( double ) and re-try o Turn on #2.06 and set #2.07=100 or more o Set Pr41= Fd If there is an Output Sinewave Filter check this Wiring !!! Possible shorted motor or motor lead between drive and motor Remove motor leads from drive and megger each free motor lead to EarthĦ00-750v for 240vac motors and 1000-1200v for 460v motors.
If drive runs up ok- megger motor for 1000v If drive trips possibly a faulty transistor. If Fd, reduce Pr42=0 and re-try Ensure Pr3 and 4 are not set too fast - set for 20 each Ensure Pr9 is not greater than 0.95 With motor disconnected, set Pr41=Fd and run drive up High OverCurrent detected on drive output-Ĭheck Pr41. O Verify the wiring between lower control terminals B2 and B4 o Verify that #6.15 is On- SyPT Lite downloads can turn this OFF O This is merely a status message indicating that the Drive Enable connection has been removed or not establish
