L4-07: Speed Agreement Detection Selection
Determines when frequency detection is active using parameters L4-01 through L4-04.
Setting 0: No Detection during Baseblock
Setting 1: Detection Always Enabled
◆
L5: Fault Restart
The drive can be set up to performs a self-diagnostic check and resume the operation after a
fault has occurred. If the self-check is successful and the cause of the fault has disappeared,
the drive restarts by performing Speed Search (refer to
b3: Speed Search on page 50 for
details).
The drive can attempt to restart itself following the faults listed below.
Use parameters L5-01 to L5-05 to set up automatic fault restart.
To output a signal during fault restart, set H2-01, H2-02, or H2-03 to 1E.
Do not use the fault restart function in hoist applications.
