L8-03
Overheat Pre-Alarm
Operation Selection
Sets the drive operation when an overheat alarm
OH is detected.
0: Ramp to Stop using the active decel time.
1: Coast to Stop.
2: Fast-stop using the time set in C1-09.
3: Alarm Only. Drive continues running, but
displays an alarm.
4: Reduced Speed Operation. Drive continues
to run with reduced frequency reference as
specified in L8-19.
Settings 0 through 2 trigger a fault relay if the
heatsink becomes too hot.

L8-05
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

L8-07
Output Phase Loss
Protection
Selects the output phase loss detection.
0: Disabled
1: Enabled (triggered by a single phase loss)
2: Enabled (triggered when two phases are lost)
Output phase loss is detected when operating
with less than 5% of the drive rated current.
Detection can mistakenly occur if the motor is
too small relative to the drive capacity rating
(this parameter should be disabled in such
cases).

Heatsink Cooling Fan
Operation Selection
Controls the heatsink cooling fan operation.
0: Fan On-Run Mode - Fan will operate only
when the drive is running and for L8-11
seconds after stop.
1: Fan always on - Cooling fan operates
whenever the drive is powered up.

Heatsink Cooling Fan
Operation Delay Time
This parameter sets the delay time for the
cooling fan to shut off after the run command is
removed when L8-10 = 0.
