6.3 Drive Alarms, Faults, and Errors
262 YASKAWA ELECTRIC SIEP C710616 35D YASKAWA AC Drive E1000 Technical Manual
■ Minor Faults and Alarms
Table 6.6 give an overview of possible alarm codes. As conditions such as overvoltage can trip both a fault and alarm, it
is important to distinguish between faults and alarms in order to find the right corrective action.
If an alarm is detected, the ALM LED will blink and the alarm code display flashes. The majority of alarms will trigger a
digital output programmed for alarm output (H2- = 10). If the ALM LED lights without blinking, this means that a
fault has been detected (not an alarm). Information on fault codes can be found in Faults on page 261.
