Overheat Alarm Level
An overheat alarm will occur if the heatsink temperature exceeds the level set in L8-02.
Default:
Min: 50
°C
Max: 150
°C
L8-03
(4AFH)
Overheat Pre-Alarm Operation
Selection
0: Ramp to stop. A fault is triggered.
1: Coast to stop. A fault is triggered.
2: Fast Stop. Decelerate to stop using the deceleration ramp in C1-09. A fault is triggered.
3: Continue operation. An alarm is triggered.
Default: 3
Min: 0
Max: 3
L8-05
(4B1H)
Input Phase Loss Protection
Selection
Selects the detection of input current phase loss, power supply voltage imbalance, or main
circuit electrolytic capacitor deterioration.
0: Disabled
1: Enabled always
2: Enabled during operation
3: Enabled during constant speed
Default: 1
Min: 0
Max: 3
L8-06
(4B2H)
Input Phase Loss Detection Level
When ripple is observed in the DC bus, expansion of the input bias is calculated and becomes
the input phase if the difference between the max and minimum values of the ripple are greater
than L8-06.
Detection Level = 100% = Voltage class
