TheStatus LED indicates general Micr oFlex e100 status information.
Solidgreen:
Drive enabled (normal operation).
Flickering / blinking green:
Firmwaredow nload / update in progress.
Solidred:
Drive disabled, but no errors are latched.
Flashingr ed:
Powerbase fault or error(s) present. The number of flashes indicates w hich
errorhas occurred.For example, to display error 3 (over current trip), the LED
flashes 3 times at 0.1 second intervals, followed by a 0.5 sec ond pause. The
sequence is repeated continuously.
Errorcode Meaning

1 DCbus overvoltagetrip................
2 IPM(integrat edpow er module) trip................
3 Overcurrenttrip................
4 Overspeed trip................
5 Feedback trip................
6 Motorover load (I2t) trip................
7 Overtemperature trip................
8 Drive overload (It) trip................
9 Followingerr or trip................
10 Error input triggered...............
11 Phases earch error...............
12 Allother err ors, including: Internal supply error, encoder..............
supply error,paramet er restore failure, power base not
recognized.
Ifmultiple error s occur at the same time, the lowest numbered error code w ill be
flashed.F or example, a MicroFlex e100 which has tripped on both feedback
error( code 5) and over-current error (code 3) will flash er ror code 3. If the drive
isalready displayingan error code when a new error with a lower c ode occurs,
thedrive w ill start flashing the new code. Note that undervoltage trip does not
appearin the table bec ause it is already indicated by the green/red flashing
state.I f an undervoltage trip occurs in conjunction with another error, the drive
willflas h the code of the additional error.
Furtherdetails abouterror codes can be found in the Mint WorkBench help file.
Press F1 and locate the Error Handling book.
Alternater ed/green flashing:
Undervoltage warning (no AC power), but no errors are latched.
TheDC -bus voltage has dropped below the powerbase undervoltage level (s ee
DRIVEBUSUNDERVOLTS).This errorwill only be generated if the drive is in the
enabledstate. C heck the AC power is connected.
