Sets terminal AM output level when selected monitor 
is at 100%.

L2-01
Momentary power loss
detection
0 to 2
0
x
A
Enables and disables the momentary power loss 
function.
0: Disabled - Unit trips on (UV1) fault when power is 
lost.
1: Power Loss Ride Thru Time - Unit will restart if 
power returns within the time set in L2-02.*
2: CPU Power Active - Unit 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.
[PwrL Selection]
L2-02
Momentary power loss
ridethru time
0.0 to 2.0
2.0
x
A
Sets the power loss ride-thru time. This value is 
dependent on the capacity of the Unit. Only effective 
when L2-01 = 1.
[PwrL Ridethru t]
L2-05
Undervoltage detection level
150 to 210 V
190
x
A
Sets the Unit’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.
[PUV Det Level]
L5-01
Number of auto restart
attempts
0 to 10
0
x
A
Sets the counter for the number of times the Unit will 
perform an automatic restart. Auto restart will check 
to see if the fault has cleared every 5 ms. When no 
fault is present, the Unit will attempt an auto restart. 
If the Unit faults after an auto restart attempt, the 
counter is incremented. When the Unit operates 
without fault for 10 minutes, the counter will reset to 
the value set in L5-01.
[Num of Restarts]
L5-02
Auto restart operation
selection
0, 1
0
x
A
Determines if the fault contact activates during an 
automatic restart attempt.
0: No Fault Relay - fault contact will not activate 
during an automatic restart attempt.
1: Fault Relay Active - fault contact will activate 
during an automatic restart attempt.

L8-02
Overheat pre-alarm level
50 to 110 deg
95
x
A
When the cooling fin temperature exceeds the value 
set in this parameter, an overheat alarm (OH) will 
occur.

x
A
Selects the Unit operation upon an OH pre-alarm 
detection.
1: Coast to Stop
3: Alarm Only
[OH Pre-Alarm Sel]
L8-07
Power supply open-phase protection 
selection
0, 1
0
x
A
Selects the detection of output current open-phase. 
When applied motor capacity is too small for Unit 
capacity, output phase loss may be detected 
inadvertently. In this case, set to 0.
0: Disabled
1: Enabled

O
A
Selects which monitor will be displayed in the 
operation menu upon power-up when o1-02 = 4.

7: Power at power side (U1-07)
8: Power supply frequency (U1-08)
