Table 5-90: Speed Agree Parameter Settings
Table 5-91: Reference Detection Parameter Settings
Parameter Display Function Range Default
L04-01 Spd Agree Level Detection level for the desired speed agree 1
and frequency detection functions. The
detection level is effective during both FWD
and REV operation. 0.0–150.0 Hz 0.0
L04-02 Spd Agree Width Detection width for speed agree 1 and
frequency detection functions. 0.0–20.0 Hz 2.0
L04-03 Spd Agree Lvl+- Detection level for the desired speed agree 2
function. The detection level is effective
during either FWD or REV operation,
depending on the set detection level (positive
value for FWD operation, negative value for
REV operation). -150.0–150.0 Hz 0.0
L04-04 Spd Agree Wdth+- Detection width for the speed agree 2
function. 0.0–20.0 Hz 2.0
Parameter Display Function Range Default
L04-05 Ref Loss Sel The VFD can detect a loss of an analog
frequency reference from input A1, A2, or A3.
Frequency reference loss is detected when
the frequency reference drops below 10% of
the reference or below 5% of the maximum
output frequency within 400 ms. 0, 1 0
0 Stop VFD stops when frequency reference is lost.
1 Run@L4-06PrevRef VFD runs at a reduced speed when the
frequency reference is lost.
L04-06 Fref at Floss Percentage of the frequency reference that
the VFD should run with when the frequency
reference is lost. 0.0–100.0% 80
L04-07 Freq Detect Sel Determines when frequency detection is
active using parameters L04-01 to L04-04. 0, 1 0
0 No Detection @BB No detection during baseblock.
1 Always Detected Detection always enabled.
