Name
Description
Display
Enables and disables the
momentary power loss
function.
0: Disabled - Drive trips on
(UV1) fault when power is
lost.
1: Power Loss Ride Thru Time
- Drive will restart if power
returns within the time set
in L2-02.*
2: CPU Power Active - Drive
will restart if power returns
prior to control power
supply shut down.*
* In order for a restart to occur,
the run command must be
maintained throughout the
ride thru period.
Sets the power loss ride-thru
time. This value is dependent
on the capacity of the Drive.
Only effective when L2-01 = 1.
Sets the minimum time to wait
to allow the residual motor
voltage to decay before the
Drive output turns back on
during power loss ride thru.
After a power loss, if L2-03 is
greater than L2-02, operation
resumes after the time set in
L2-03.
Sets the time it takes the output
voltage to return to the preset
V/f pattern after speed search
(current detection mode) is
complete.
Sets the Drive's DC Bus
undervoltage trip level. If this is
set lower than the factory
setting, additional AC input
reactance or DC bus reactance
may be necessary. Consult the
factory before changing this
parameter setting.
