YASKAWA ELECTRIC TOEP C710687 03B FSDrive-MV1000 Parameter Guide 69
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)
Triggered when the output current falls below 5% of the drive rated current.
Disable this parameter when output phase loss detection is mistakenly
triggered because the motor rate current is very small compared to the drive
capacity.
Default: 2
Min: 0
Max: 2
219
L8-09
(4B5H)
Output Ground Fault
Detection Selection
0: Disabled
1: Enabled
Default: 1
Min: 0
Max: 1
219
L8-10
(4B6H)
Cooling Fan
Operation Selection
0: During run only. Fan operates only during run and for L8-11 seconds after
stop.
1: Cooling fan operates when Uv (DC bus undervoltage) is cleared.
2: Fan always on. Cooling fan operates whenever the drive is control
powered up.
Default: 1
Min: 0
Max: 2
220
L8-11
(4B7H)
Cooling Fan Off
Delay Time
Sets a delay time to shut off the cooling fan after the Run command is
removed when L8-10 = 0.
Default: 600 s
Min: 0 s
Max: 1800 s
220
L8-15
(4BBH)
oL2 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
220
L8-18
(4BEH)
Software CLA
Selection
Enables or disables the software current limits.
0: Disabled
1: Enabled
Default: 1
Min: 0
Max: 1
220
L8-19
(4BFH)
Frequency
Reduction Rate
during Overheat
Pre-Alarm
Specifies the frequency reference reduction gain at overheat pre-alarm when
L8-03 = 4.
Default: 0.8
Min: 0.1
Max: 0.9
219
L8-32
(3104H)
Backup Fan Use
Selection
Sets whether the backup fan is used or not.
0: Backup fan used
1: No backup fan used
Default: 1
Min: 0
Max: 1
221
L8-33
(3105H)
Fan Board Use
Sele
ction
Sets the
number of fan control boards (FFB boards) used.
0: No fan boards used
1: One fan board used
2: Two fan boards used
Default:
<6>
Min: 0
Max: 2
221
L8-63
(3112H)
Output Overvoltage
Detection Level
Sets the level at which overvoltage is detected on the output side. Set as a
percentage of the maximum voltage of the motor in 0.1% units.
Default: 120.0%
Min: 0.0%
Max: 200.0%
221
L8-64
(3113H)
Output Overvoltage
Detection Time
Sets the time before OOV (overvoltage at the output side) is detected in 0.01
s units. If the state in which the output voltage exceeds the value set to L8-63
continues for the time set to L8-64 or longer, OOV (overvoltage at the output
side) is detected.
Default: 0.01 s
Min: 0.00 s
Max: 2.00 s
221
L8-65
(3114H)
Output Voltage
Unbalance
Detection Operation
Selection
Sets the operation when an output voltage unbalance is detected.
0: Ramp to stop over the time set for C1-02 (Deceleration Time)
1: Coast to stop
2: Fast Stop over the time set for C1-09 (Fast Stop Time)
3: Alarm only
Default: 3
Min: 0
Max: 3
221
No.
