Parameter 48 -- RideĆThru Restart
Units = Code
Range = 0/1/2
Factory Setting = 0
For all control schemes, this parameter selects the drive restart action taken
if input power is interrupted and restored within 100 ms. Restart settings 1
and 2 in Parameter 48 will override any settings made in Parameter 47.
•
When set to 0, if power is removed for 15 ms, Ride-Thru Restart is
disabled and the drive will generate an
LU
fault. The drive will not
restart until the fault is cleared by first issuing a drive stop command,
then a start command. The drive will then restart and ramp to the last
selected speed.
•
When set to 1, if power is removed for 15 ms, the drive will generate an
LU
fault. If power is restored within 100 ms (or longer depending on
load), the drive will restart from zero speed, then ramp to the last
selected speed after the initial waiting time set by Parameter 49.
•
When set to 2, if power is removed for 15 ms, the drive will generate an
LU
fault. If power is restored within 100 ms (or longer depending on
load), the drive will continue to operate at the selected speed. If longer
than 100 ms, the drive will restart only after the initial waiting time set
by Parameter 49.
Parameter 49 -- Restart Time Select
Units = Seconds
Range = 000.1/100.0
Factory Setting = 000.1
This parameter sets the time the drive will wait before acting on a restart
command after an LU fault has occurred. The value of Parameter 49 is
selectable in 0.1 second increments.
