YASKAWA TM.V1000.01 V1000 Drive Installation & Start-Up Manual (Preliminary 01-19-07)
Description
These parameters configure the Multi-Function
Output (H2- = 13, 14, 15, 16) settings
"Fref/Fout Agree 2", "Fref/Set Agree 2",
"Frequency Detection 3," or "Frequency
Detection 4".
Parameter L4-03 sets the level while parameter
L4-04 sets the hysteresis for the Speed
Detection Output Function.
Refer to L4-03.
Sets drive action when the frequency reference
is lost. The frequency reference is considered
lost when reference drops 90% or more of its
current value for 400 ms.
0: Stop - Drive will stop.
1: Run at L4-06 PrevRef - Drive will run at the
percentage set in L4-06 of the frequency
reference level at the time frequency reference
is lost.
If the frequency reference loss function is
enabled (L4-05 = 1) and frequency reference is
lost, the drive will run at a reduced frequency
reference determined by the following
formula:
Fref = Fref at time of loss L4-06.
0: No detection during baseblock.
1: Detection always enabled.
L5: Fault Reset
Use L5 parameters to configure Automatic Restart after fault.
Sets the counter for the number of times the
drive will perform an automatic restart on the
following faults: GF, LF, OC, OV, PF, PUF,
RH, RR, OL1, OL2, OL3, OL4, UV1.
Auto restart will check if the fault has cleared
every 5 ms.
When no fault is present, the drive will attempt
an auto restart.
If the drive faults after an auto restart attempt,
the counter is incremented.
When the drive operates without fault for 10
minutes, the counter will reset to the value set
in L5-01.
