All Modes
0: Disabled
1: Enabled
All Modes
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.
All Modes
removed when L8-10 = 0.
All Modes
0: No oL2 level reduction below 6 Hz.
1: oL2 level is reduced linearly below 6 Hz. It is halved at 0 Hz.
All Modes
Enables or disables the software current limits.
0: Disabled
1: Enabled
All Modes
Specifies the frequency reference reduction gain at overheat pre-alarm
when L8-03 = 4.
All Modes
Sets whether the backup fan is used or not.
0: Backup fan used
1: No backup fan used
All Modes
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
All Modes
Sets the level at which overvoltage is detected on the output side. Set as a
percentage of the motor's maximum voltage in 0.1% units.
All Modes
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.
All Modes
Sets the operation when an output voltage imbalance 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
All Modes
Sets the level at which imbalance of the output voltage is detected in 0.1%
units (100%: 2400 V for the 2.4 kV class, 3300 V for the 3 kV class, 4160
V for the 4.16 kV class, 6600 V for the 6 kV class, and 11000 V for the 11
kV class).
