7.2 MicroFlex e100 indicators

7.2.1 STATUS LED

The Status LED indicates general MicroFlex e100 status information.

Solid green:

Drive enabled (normal operation).

Flickering / blinking green:

Firmware download / update in progress.

Solid red:

Drive disabled, but no errors are latched.

Flashing red:

Powerbase fault or error(s) present. The number of flashes indicates which error has occurred. For example, to display error 3 (overcurrent trip), the LED flashes 3 times at 0.1 second intervals, followed by a 0.5 second pause. The sequence is repeated continuously.

Error code	Meaning
(no. of flashes)
1	DC bus overvoltage trip.
2	IPM (integrated power module) trip.
3	Overcurrent trip.
4	Overspeed trip.
5	Feedback trip.
6	Motor overload (I2t) trip.
7	Overtemperature trip.
8	Drive overload (It) trip.
9	Following error trip.

10. . . . . . . . . . . . . . Error input triggered.

11. . . . . . . . . . . . . . Phase search error.

12. . . . . . . . . . . . . . All other errors, including: Internal supply error, encoder supply error, parameter restore failure, power base not recognized.

If multiple errors occur at the same time, the lowest numbered error code will be flashed. For example, a MicroFlex e100 which has tripped on both feedback error (code 5) and over-current error (code 3) will flash error code 3. If the drive is already displaying an error code when a new error with a lower code occurs, the drive will start flashing the new code. Note that undervoltage trip does not appear in the table because it is already indicated by the green/red flashing state. If an undervoltage trip occurs in conjunction with another error, the drive will flash the code of the additional error.

Further details about error codes can be found in the Mint WorkBench help file. Press F1 and locate the Error Handling book.

Alternate red/green flashing:

Undervoltage warning (no AC power), but no errors are latched.

The DC-bus voltage has dropped below the powerbase undervoltage level (see DRIVEBUSUNDERVOLTS). This error will only be generated if the drive is in the enabled state. Check the AC power is connected.
