u
n: Special Adjustment
The n parameters adjust more advanced performance characteristics such as Hunting Prevention and Speed Feedback
Detection Control.
L8-66
(3115H)
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 2.4 kV class and 4160 V for the 4.16 kV class).
Default: 10.0%
Min: 0.0%
Max: 100.0%
221
L8-67
(3116H)
Output Voltage
Unbalance
Detection Time
Sets the time before output voltage unbalance is detected in 0.001 s units. If
the state in which the zero-phase voltage detection value exceeds the level
set to L8-66 continues for the time set to L8-67 or longer, VUB (output
voltage unbalance) is detected.
Default: 0.200 s
Min: 0.001 s
Max: 2.000 s
222
L8-86
(3100H)
Transformer
Overheat Alarm
(TMA) Operation
Selection
Sets the operation when a TMA (Transformer Overheat Alarm) 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: Continue operation. TMA alarm is triggered.
Default: 3
Min: 0
Max: 3
222
L8-87
(3101H)
Transformer
Overheat Alarm
(TMA) Level
Sets the detection temperature for TMA alarm function in
°
C units.
Note: An alarm is detected when the detected transformer
temperature reaches the value set here.
Default:
<6>
Min: 50 ° C
Max: 160

L8-88
(3102H)
Transformer
Overheat Fault
(TME) Level
Sets the detection temperature for TME fault function in
°
C units.
Default:
<6>
Min: 50
°
C
Max: 160

<3> Parameter setting value is not reset to the default value when the drive is initialized (A1-03 = 1110/2220).
<6> Default setting is determined by o2-04, Drive Model Selection.
<8> The setting range changes if the value of the motor rated capacity (E2-11) is changed by Auto-Tuning or manual setting.
<10> Default setting is determined by A1-02, Control Method Selection.
<12> The setting range for the acceleration and deceleration times is determined by the accel/decel time setting units in C1-10. For example, if the
accel/decel time setting units are set to 0.01 s (C1-10 = 0), the setting range becomes 0.00 to 600.00 s.
<16> Default setting is determined by A1-02, Control Method Selection, and o2-04, Drive Model Selection.
<20> The range upper limit is determined by E1-04, Maximum Output Frequency, and E1-04, Frequency Reference Upper Limit.

Hunting Prevention
Gain while in
Reverse
Sets the gain used for Hunting Prevention. If set to 0, the gain set to n1-02 is
used for operation in reverse.
