Fref Loss Detection
Selection
Sets the operation when the drive detects a loss of frequency reference.
1
(0, 1)
Enables the detection of a loss of an analog frequency reference when MFAI terminals (A1 and A2) input the
frequency reference. Set
H2-01 to H2-03 = C [MFDO Function Selection = Frequency Reference Loss]
to enable this
function.
If the frequency reference is less than 10% in 400 ms, the drive detects frequency reference loss.
Figure 5.75 Detection of Frequency Reference Loss
0 : Stop
The drive follows the frequency reference and stops the motor.
1 : Run at (L4-06 x Last Reference)
The drive continues to operate at the frequency reference value set in
L4-06 [FreqReference at Reference Loss]
. When
you return the external frequency reference value, the drive continues to operate with the frequency reference.
