L8-12
Ambient Temperature
Setting
Enter the ambient temperature. This value adjusts the oL2 detection level.
Default: 40 °C
Min: -10 °C
Max: 50 °C
L8-15
oL2 (drive overload)
Characteristics Selection at
Low Speeds
0: No oL2 level reduction below 6 Hz.
1: oL2 level is reduced linearly below 6 Hz. It is halved at 0 Hz.
Default: 1
Min: 0
Max: 1
L8-27
Overcurrent Detection
Gain
Sets the gain for overcurrent detection as a percentage of the motor rated current.
Overcurrent is detected using the drive’s overcurrent level or the value set to L8-27,
whichever is lower. Default: 300.0%
Min: 0.0%
Max: 300.0%
L8-29
Current Unbalance
Detection (LF2) 0: Disabled
1: Enabled
Default: 1
Min: 0
Max: 1

<1>
Installation Selection
0: IP00 enclosure drive
2: IP00 enclosure drive with top protective cover
Default:
<4>
Min: 0
Max: 2
L8-38
Automatic Torque Boost
Selection
Torque Boost increases the output current limit while decreasing the carrier frequency
when the output current exceeds a certain value.
0: Disabled
3: Enabled
Default: 0
Min: 0
Max: 3
L8-39
Reduced Carrier
Frequency
Sets the reduced carrier frequency used by the Torque Boost function.
Default: 3.0 kHz
Min: 1.0 kHz
Max: 15.0 kHz
L8-55
Internal Braking Transistor
Protection
0: Disabled. L8-55 should be disabled when using a regen converter or an optional
braking unit.
1: Protection enabled. Default: 1
Min: 0
Max: 1
L8-62
Operation Selection at
Input Phase Loss
Sets stopping method when a Input phase loss fault (PF) occurs. See parameter L8-05.
0: Ramp to Stop - Decelerate to stop using the deceleration ramp in C1-02.
1: Coast to Stop
2: Fast Stop - Decelerate to stop using the deceleration ramp in C1-09.
3: Alarm only - Drive continues operation.
Default: 1
Min: 0
Max: 3
L8-77 Oscillation Suppression

the same frequency as the output frequency.
Default: 0
Min: -100
Max: 100
L8-88
Safe Disable Operation
Mode 0: Mode 0
1: Mode 1
Default: 1
Min: 0

Selection
Enables or disables the Current Monitoring function.
0: Disabled
1: Enabled Default: 0
Min: 0
Max: 1
L8-99
<44>
Current Monitoring Level
Sets the current monitoring level as a percentage of the drive’s rated current. Sets the
level of current used for L8-89 and H2-
= 5C.
Default: 10.0%
Min: 0.0%
Max: 50.0%
<1> Parameter setting value is not reset to the default value when the drive is initialized.
<4> Default setting is determined by the drive model (o2-04).
