Correct to proper temperature range.
Correct ambient temp./lower braking duty cycle.
AC supply voltage not within permissible limits.. ............ Check inverter specs and adjust AC supply voltage.
Circuit breaker is open .................................................... Close circuit breaker.
Open AC supply phase .................................................... Correct input wiring and check AC supply fuses.
Other than above ............................................................ Check customer power supply
Electronic thermal overload set incorrectly .................... Check Function Code 1 b.
Load is over permissible limits ........................................ Reduce load.
Correct Function Code selection

than high limit frequency) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Check Function Codes 1 4 and 15.
Electrical noise source close to inverter . . . . . . . . . . . . . . . . . . . . . . . . Take noise prevention measures.
Check to make sure noise is not coming into
terminals
or “CM”.
A Function Code that cannot be set while
running has been attempted to be set . . . . . . . . . . . . . . . . . . . . . . . . . . . . Attempt to change only those Function Codes in
TABLE 5 marked with while inverter is running.
Normal stored data settings (Stored setting
data has been determined to be abnormal.) . . . . . . . . . . . . . . . . . . Replace Main Control card.
NOTE: may be possible to clear this
condition by removing and reinserting any
integrated circuit chips on the Main
Card (total of three).
NOTE: Motor coast-to-stop when condition is displayed. After information and correcting the
cause of the problem, reset by pressing the on Keypad Panel or momentarily close contact between the
RST-CM circuit terminals (after the motor has stopped}.
NOTE: If a fault cannot reset, check to sure that a RUN command is notpresent.
NOTE: may be displayed when the AC supply is switched OFF and does not indicate any abnormality.
