(4AEH)
Overheat Alarm Level
A n overheat alarm w ill occur if the heatsink temperature exceeds the level set in L8-02.
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: Emergency Stop. Decelerate to stop using the deceleration ramp in C1-09. A fault is
triggered.
3: Continue operation. An alarm is triggered.
L8-05
(4B1H)
Input Phase Loss Protection
Selection
Selects the detection o f input current phase loss, power supply voltage imbalance, or main
circuit electrolytic capacitor deterioration.
Disabled
Enabled always
Enabled during operation
Enabled during constant speed
L8-06
(4B2H)
Input Phase Loss Detection Level
W hen ripple is observed in the DC bus, expansion o f the input bias is calculated and becom es
the input phase i f the difference between the max and minimum values o f the ripple are greater
than L8-06.
Detection L evel = 100% = Voltage class x V 2(determ ines standards for setting values)

(4B6H)
Heatsink Cooling Fan Operation
Selection
During run only. Fan operates only during run and for L8-11 seconds after stop.
Fan always on. Cooling fan operates whenever the drive is powered up.
Temperature controlled operation.
L8-11
(4B7H)
Heatsink Cooling Fan O ff Delay
Time
Sets a delay tim e to shut o ff the cooling fan after the U p/Dow n command is removed when L8
10 = 0.
L8-12
(4B 8H )
Am bient Temperature Setting
Enter the ambient temperature. This value adjusts the oL2 detection level.

oL2 (drive overload)
Characteristics Selection at Low
Speeds
0: N o oL2 level reduction below 6 Hz.
1: oL2 level is reduced linearly below 6 Hz. It is halved at 0 Hz.

Overcurrent Detection Gain
CLV
■
CLV/PM
Sets the gain for overcurrent detection as a percentage o f the motor rated current. Overcurrent is
detected using the drive’s overcurrent level or the value set to L8-27, whichever is lower.
