5.3 Drive Alarms, Faults, and Errors
<2> Displayed as CPF20 when occurring at drive power up. When one of the faults occurs after successfully starting the drive, the display will show
CPF21.
<3> Fault histories are not kept when CPF00, CPF01, CPF06, CPF24, oFA00, oFb00, oFC00, Uv1, Uv2, or Uv3 occur.
n Minor Faults and Alarms
Refer to Table 5.6 for an overview of possible alarm codes. Conditions such as overvoltages can trip faults and alarms. It is
important to distinguish between faults and alarms to determine the proper corrective actions.
When the drive detects an alarm, the ALM indicator LED blinks and the alarm code display flashes. Most alarms trigger a
digital output programmed for alarm output (H2-oo = 10). A fault (not an alarm) is present if the ALM LED lights without
blinking. Refer to Faults on page 197
