FrefLoss Det.Selection
Sets the operation when the drive detects a loss of frequency reference.
1
(1, 2)
Enables the detection of a loss of an analog frequency reference when MFAI terminals (AI1 and AI2) input the
frequency reference. Set H2-01 to H2-03 = 4B [MFDO Function Select = FreqRef Loss] to enable this function.
If the frequency reference is less than 10% in 400 ms, the drive detects frequency reference loss.
