Mitsubishi Electric FR-A820-00046 Instruction Manual page 489

Parameters
NOTES Use the retry function only when the operation can be resumed after resetting a protective func-
tion activation. Making a retry against the protective function, which is activated by an unknown
condition, will lead the inverter and motor to be faulty. Identify in what condition the protective
function was activated, and eliminate such condition before resuming the operation.
If the retry function operates during PU operations, the operating conditions (forward/reverse
rotation) are stored; and operations resume after retry reset.
Only the fault details for the first fault that occurred are stored in the faults history.
The reset by the retry function does not clear the accumulated data of the electronic thermal O/L
relay, regenerative brake duty, etc. (This is different from power supply reset or reset by RES sig-
nal.)
When the parameter storage device fault (E.PE) is occurring and reading of the retry-function-
related parameters is not possible, retry cannot operated.
Changing the terminal assignment using Pr. 190 to Pr. 196 (output terminal function selection)
may affect the other functions. Set parameters after confirming the function of each terminal.
CAUTION:
E
When the retry function is set enabled, stay away from the motor and machine in the case of an
inverter trip. The motor and machine will start suddenly (after the reset time has elapsed) after
the inverter trip. When the retry function is set enabled, apply in easily visible places the
CAUTION stickers supplied to this product.
