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)
<3>
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
226
L8-09
(4B5H)
Output Ground Fault Detection
Selection
0: Disabled
1: Enabled
Default: 1
Min: 0
Max: 1 227
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: 2 227
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 227
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
227
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: 1 228
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% 228
L8-29
(4DFH)
Current Unbalance Detection
(LF2)
0: Disabled
1: Enabled
Default: 1
Min: 0
Max: 1 228
L8-35
(4ECH)
<4>
Installation Selection
0: IP00 enclosure drive
2: IP00 enclosure drive with top protective cover
Default: <1>
Min: 0
Max: 2 228
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: 3 229
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
229
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: 1 229
L8-62
(529H)
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
226
L8-77
(61EH)
Oscillation Suppression
Used to suppress speed oscillations that occur with an unloaded motor and that have the same
frequency as the output frequency.
Default: 0
Min: -100
Max: 100
230
L8-88
(2F5H)
Safe Disable Operation Mode
0: Mode 0
1: Mode 1
Default: 1
Min: 0
Max: 1
