Direction Calculation Setup (L123)
L123 is a byte parameter. Depending on setting of bit 0, 1 and 2, behavior of deliverance operation is
decided.
bit Bit setting description
bit0
Activation
0: Function disabled.
If BATRY input function is enabled, inverter will behave as current
FRENIC-Lift during rescue mode. In other words, motor will turn
FWD or REV depending on input terminal activation.
1: Function enabled.
If
BATRY
input is activated, motor will turn in different directions
depending on the setting of
bit1
,
bit2
,
L123
and
L124
.
bit1
Input power level
reached criteria
0: Cancel deliverance operation
If during calculation, it is detected that in both directions (FWD
and REV), level 121 is reached, deliverance operation is stopped.
In other words, inverter will not try to run the motor to any
direction
1: Take the direction with the highest output frequency.
In this case, the selected direction will be the one with the highest
output frequency when the Input power detection level is reached.
bit2
Directions test
criteria
0: Move in FWD direction
Regardless of input terminal activation (RUN command),
deliverance operation will turn the motor always in FWD direction.
If level 121 is not reached, deliverance operation will be finished
when RUN command is removed.
1: Move in FWD and REV direction
Regardless of input terminal activation (RUN command),
deliverance operation will turn the motor always in FWD direction.
After few seconds motor will be stopped and REV direction will be
tested. Deliverance operation will be finished in the direction of
the RUN command with the lowest input power consumption.
■
Direction Calculation Delay Timer (L124)
Calculation of deliverance operation will start after the time set on L124 is elapsed.
- Data setting range: 0.00 to 1.00 s
L125 UPS/batteries minimum operation level
Minimum battery operation level can be defined in this function code. If batteries or UPS are not
supplying enough voltage on the DC link to perform battery operation, inverter will be locked by LV
alarm. By means of this level, battery operation is aborted if DC link voltage is not enough to
perform battery operation.
If DC link voltage is above L125 level, rescue operation can be performed (is allowed). If DC link
voltage is below or equal to L125 level, rescue operation cannot be performed, inverter will trip LV
as soon as RUN command ( FWD or REV ) is given; even BATRY function is activated in any input.
In figure 1, a rescue operation sequence when DC link voltage is above L125 level is shown.
