Hardware Protection
L8-01
Internal Dynamic Braking
Resistor Protection Selection
DB Resistor Prot
Selects the DB protection only when using 3% duty cycle heatsink
mount Yaskawa braking resistor. This parameter does not enable or
disable the DB function of the Drive.

Overheat Alarm Level
OH Pre-Alarm Lvl When the cooling fin temperature exceeds the value set in this
parameter, an overheat alarm (OH) will occur. 50 to
130
95°C A A A A
L8-03
Overheat Pre-Alarm
Operation Selection
OH Pre-Alarm Sel
Selects the Drive operation upon an OH pre-alarm detection.
0: Ramp to Stop
1: Coast to Stop
2: Fast-Stop
3: Alarm Only
0 to 3 3 A A A A
L8-05
Input Phase Loss Protection
Selection
Ph Loss In Sel
Selects the detection of input current phase loss, power supply volt-
age imbalance, or main circuit electrostatic capacitor deterioration.
0: Disabled
1: Enabled
0 to 1 1 A A A A
L8-07
Output Phase Loss Protection
Ph Loss Out Sel
Selects the detection of output current open-phase.
When applied motor capacity is too small for Drive capacity,
output phase loss may be detected inadvertently. In this case, set to 0.
0: Disabled
1: 1-phase Loss Detection
2: 2/3-phase Loss Detection
0 to 1 1 A A A A
L8-09
Output Ground Fault
Detection Selection
Ground Fault Sel Enables and disables the Drive’s output ground fault detection.
0: Disabled
1: Enabled

L8-10
Heatsink Cooling Fan
Operation Selection
Fan On/Off Sel
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 RUN is removed.
1: Fan Always On - Cooling fan operates whenever the Drive is
powered up.)
0 to 1 0 A A A A
L8-11
Heatsink Cooling Fan
Operation Delay Time
Fan Delay Time
This parameter sets the delay time for the cooling fan turn off after
the run command is removed when L8-10 = 0.
0 to 300 60sec A A A A
L8-12
Ambient Temperature Setting
Ambient Temp When the Drive is installed in an ambient temperature exceeding
its rating, the Drive overload (OL2) protection level is adjusted.
45 to 60 45°C A A A A
Denotes that parameter can be changed when the Drive is running.
