 Parameter
(Ex.1) When [bb-20] = 00, tripping occurs
(Ex.2) When [bb-20] ≠00 and [bb-24] = 00, it restarts at 0 Hz.
Note The motor will trip after instantaneous power failure allowable time.
Item Parameter Data Description
Default
data
The number of retries
after instantaneous
power failure
[bb-20]
0 to 16/ ∞(255)
(Counts)
Sets the retry counts in case of instanta-
neous power failure.
If this is set to 0, the motor will trip upon
recovery from instantaneous power failure.

01
01 Restarts with the frequency matching
02 Restarts upon frequency pull-in
03
