<1> Default setting is dependent on parameter o2-04, Drive Model Selection.
<2> Parameter setting value is not reset to the default value when the drive is initialized.
<3> Default setting is determined by the drive model:
Setting 2: Model code CIMR-Po2A0004 to 2A0211, 4A0002 to 4A0165, and 5A0003 to 5A0242
Setting 0: Model code CIMR-Po2A0250 to 2A0415 and 4A0208 to 4A0675

Specifies the frequency reference reduction gain at overheat pre-alarm when
L8-03 = 4.
Determines drive response when a fault occurs with the internal cooling fan.
0: Ramp to stop
1: Coast to stop
2: Fast stop (Decelerate to stop using the deceleration time set to C1-09)
3: Alarm only ("FAn" will flash)
4: Continue operation at reduced speed as set to L8-19.
0: IP00/Open-Chassis enclosure
1: Side-by-Side mounting
2: IP20/NEMA Type 1 enclosure
3: Finless model drive or external heatsink installation
0: Disabled
1: Enabled below 6 Hz
2: Enabled for the entire speed range
Sets the time that the drive continues running with reduced carrier frequency
after the carrier reduction condition is gone. Setting 0.00 s disables the carrier
frequency reduction time.
0: Disabled
1: Enabled. An alarm is triggered at output currents above 150% of drive rated
current.
0: Disabled. Disable when using a regen converter or optional braking unit.
1: Protection enabled.
Sets the amount of time until baseblock is executed after detecting pull-out at
low speed.
Determines the detection level of pull-out at low speed.
Sets the average number of times pull-out can occur at low speed.
