n L8-32: Backup Fan Use Selection
Sets whether the backup fan is used.
Setting 0: Backup fan provided
Setting 1: No backup fan
n L8-33: Fan Board Use Selection
Sets the number of fan control boards (FFB boards) used.
Setting 0: No fan boards used
Setting 1: One fan board used
Setting 2: Two fan boards used
n L8-63: Output Side Overvoltage Detection Level
Parameter L8-63 sets the detection level for overvoltage at the output side. Set as a percentage of the maximum motor
voltage in 0.1% units.
n
L8-64: Output Overvoltage Detection Time
Sets the time before an Output Overvoltage (OOV) is detected, in 0.01 s units. If the state in which the output voltage
exceeds the value set for L8-63 continues for the time set for L8-64 or longer, Output Overvoltage (OOV) is detected.
n
L8-65: Output Voltage Unbalance Detection Operation Selection
Sets the action the drive should take when an output voltage unbalance is detected.
Setting 0: Ramp to stop using the deceleration time set in C1-02
Setting 1: Coast to stop
Setting 2: Ramp to stop using the Fast Stop time set in C1-09
Setting 3: Alarm only
n L8-66: Output Voltage Unbalance Detection Level
Sets the level at which unbalance of the output voltage is detected in 0.1% units (100%: 2400 V for the 2 kV class,
3300 V for the 3 kV class, 4160 V for the 4 kV class, 6600 V for the 6 kV class, 11000 V for the 11 kV class).
No. Name Setting Range Default

L8-64 Output Overvoltage Detection Time 0.00 to 2.00 s 0.01 s
No. Name Setting Range Default
L8-65
Output Voltage Unbalance Detection Operation
Selection
0 to 3 3
No. Name Setting Range Default
L8-66 Output Voltage Unbalance Detection Level 0.0 to 100.0% 10.0%
