Storage temperature (Note 3)
Note: 1. Jog operation may also be performed from the operation panel or parameter unit.
2. Not provided for the FR-A520-11K to 55K-NA and FR-A540-11K to 55K-NA/-EC which do not
have a plug-in brake circuit.
3. Temperature applicable for a short period in transit, etc.
Selection can be made from output frequency, motor current (steady or peak value), output
voltage, frequency setting, running speed, motor torque, overload, converter output voltage
(steady or peak value), electronic overcurrent protection load factor, input power, output power,
load meter, motor exciting current, cumulative energization timecumulative, actual operation
watt-hour meter, regenerative brake duty and motor load factor.
Alarm definition is displayed when protective function is activated. 8 alarm definitions are stored.
(Four alarm definitions are only displayed on the operation panel.)
Input terminal signal states, output terminal signal states, option fitting status, terminal
Output voltage/current/frequency/cumulative energization time immediately before protective
function is activated
