L8-40: CarrierFreqReduct Off DelayTime
No.
Name
(Hex.)
L8-40 CarrierFreqReduct
Off DelayTime
(04F1)
When L8-40 is set to a value other than 0.00, the carrier frequency reduction function is enabled during startup.
The carrier frequency is automatically reduced when operation starts. After the time set in L8-40 elapses, the
carrier frequency returns to the value set in C6-02 [Carrier Frequency Selection].
When L8-38 = 1, 2 [Carrier Frequency Reduction = Enabled], L8-40 is also applied as the time taken for the
carrier frequency to return to its configured value after being reduced.

L8-41 High Current Alarm
Selection
(04F2)
0 : Disabled
An HCA is not detected.
1 : Enabled
An HCA is triggered when the output current exceeds 150% of the drive rated current.
The MFDO terminal set for an alarm [H2-01 to H2-04 = 10] turns on.

V/f CL-V/f OLV CLV AOLV
Sets the time (off delay time) taken for the automatically reduced carrier
frequency to return to the state before the reduction.
V/f CL-V/f OLV CLV AOLV
Triggers an HCA [Current Alarm] when the output current exceeds 150% of
the drive rated current.
V/f CL-V/f OLV CLV AOLV
Sets the STPo [Desynchronization Error] on the basis of the output current.
V/f CL-V/f OLV CLV AOLV

the ACR integral value.
V/f CL-V/f OLV CLV AOLV
Sets the time until STPo is detected after the value of L8-51 [STPo I
Detection Level] is exceeded.
V/f CL-V/f OLV CLV AOLV
Enables or disables the Id deviation detection function for STPo
[Desynchronization Error].
