L8-07
(4B3H)
Output Phase Loss Protection
Selection
0: Disabled
1: Enabled (triggered by a single phase loss)
2: Enabled (triggered when two phases are lost)
3: Enabled (triggered at phase loss at start or when two phases lost mid-
operation)
Output phase loss fault (LF) is triggered when the output current falls below 5%
of the drive rated output current.
Output phase loss fault can mistakenly be triggered if the motor's rated current is
very small compared to the drive rating. Disable this parameter in such cases.
Default: 0
Min: 0
Max: 3
L8-09
(4B5H)
Output Ground Fault
Detection Selection
0: Disabled
1: Enabled
Default: 1
Min: 0
Max: 1
L8-10
(4B6H)
Heatsink Cooling Fan
Operation Selection
0: Run with timer (Fan operates only during run and for L8-11 seconds after
stop.)
1: Run always (Cooling fan operates whenever the drive is powered up.)
2: Temperature controlled (Cooling fan operated depending on the temperature
of the drives heatsink.)
Default: 0
Min: 0
Max: 2
L8-11
(4B7H)
Heatsink Cooling Fan Off
Delay Time
Sets a delay time to shut off the cooling fan after the Up/Down command is
removed when
L8-10 = 0.
Default: 60 s
Min: 0 s
Max: 300 s
L8-12
(4B8H)
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
(4BBH)
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
(4DDH)
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
(4DFH)
Current Unbalance Detection
(LF2)
0: Disabled
1: Enabled
Default: 1
Min: 0
Max: 1
L8-35
(4ECH)
Installation Selection
0: IP00 enclosure drive
2: IP00 enclosure drive with top protective cover
Default:
Min: 0
Max: 2
L8-38
(4EFH)
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
(4F0H)
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
(45FH)
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
No.
