13.5.2 Automatic Error Reset
Automatic error reset function is used to ensure continuous running without hu-
man intervention in the case of occasional errors, such as overcurrent or over-
voltage at start or in the run mode. This function can be activated by setting
[E9.00] ≠ 0.
When an error occurs, the frequency converter stops the output and the related
error code is displayed at the same time. The system remains in idle mode for
delay time [E9.01]. Then the error will automatically be reset and a run com-
mand will be generated to restart the frequency converter. This sequence will be
performed [E9.00] times. If the error still exists, the frequency converter re-
mains in idle mode and no longer performs automatic restart attempts. In this
case, a manual error reset is required to resume the operation.
Automatic error reset is valid for the following errors: OC-1, OC-2, OC-3, OE-1,
OE-2, OE-3, OE-4, OL-1, OL-2, UE-1*, E-St and OH.
Code Name Setting range Default Min. Attri.
E9.00 Automatic error reset attempts 0...3 (0: Inactive) 0 – Stop
E9.01 Automatic error reset interval 0.1...60.0 s 10.0 0.1 Stop
E9.02 Automatic error reset attempts re-
start time
0…65,535 0 1 Stop
Parameter E9.02 can be used to reset the internal error rest attempts back to
the value from [E9.00] in case there are no error events inside this restart time.
The number of reset attempts is reset to [E9.00] when E9.02 is set to a value
different to 0 and there are no error reset events inside the interval given from
the value of parameter E9.02.
*:
1. If [E9.00] ≠ 0 and [E0.45] = 0, every time error ‘UE-1’ resets,
the remaining times of automatic reset would decrease.
2. If [E9.00] ≠ 0 and [E0.45] ≠ 0, then reset time of error "UE-1" is
without limitation.
3. If [E9.00] = 0 and [E0.45] ≠ 0, then reset time of error "UE-1" is
without limitation.
13.5.3 Error Reset by Digital Input
The error reset input can be defined with one digital input. This function works
in the same manner as the panel error reset function does, which allows remote
error reset. 'Error reset' is edge sensitive.
