7-2 Troubleshooting MN1919
7.2 Status LED
The Status LED indicates general MicroFlex status information.
Solid green:
Drive enabled (normal operation).
Flashing green:
Firmware download 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.

If multiple errors occur at the same time, the lowest numbered error code will be
flashed. For example, a MicroFlex 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
DRIVEERROR
and
AXISERROR
keywords, or the
Error
Handling
book.
Alternate red/green flashing:
Undervoltage warning (no AC power). The DC-bus voltage has dropped below
the powerbase undervoltage level (see DRIVEBUSUNDERVOLTS ). Check that
AC power is connected. This error will be automatically cleared when AC power
is restored, so the MicroFlex does not need to be reset.
