<3> Parameter setting value is not reset to the default value when the drive is initialized.
<9> Default setting is determined by the drive model (o2-04).
<10> Default setting is determined by the control mode (A1-02).
<16> Default setting is determined by the control mode (A1-02) and the drive model (o2-04).

All Modes
0: Disabled
1: Enable (triggered when single phase is lost)
2: Enabled (triggered when two phases are lost)
All Modes
0: Disabled
1: Enabled
All Modes
0: Run with timer. Fan operates only during run and for L8-11 seconds after stop.
1: Run always. Cooling fan operates whenever the drive is powered up.
All Modes
Sets a delay time to shut off the cooling fan after the Run command is removed when L8-10 = 0.
All Modes
Enter the ambient temperature. This value adjusts the oL2 detection level.
All Modes
0: Protection disabled at low speed.
1: Protection enabled at low speed.
V/f OLV/PM
0: Software CLA disabled (gain=0)
1: Software CLA enabled
All Modes
Specifies the frequency reference reduction gain at overheat pre-alarm when L8-03 = 4.
V/f OLV/PM
Sets the gain for overcurrent detection as a percentage of the motor rated current. Overcurrent is
detected using the drive's overcurrent level or the value set to L8-27, whichever is lower.
V/f OLV/PM
0: Disabled
1: Enabled
All Modes
Determines the action the drive should take when a fault occurs with the internal cooling fan.
0: Ramp to stop with C1-02
1: Coast to stop
2: Ramp to stop with fast stop C1-09
3: Alarm only
All Modes
0: IP00 enclosure
1: Side-by-Side mounting
2: IP20/NEMA 1, UL Type 1 enclosure
3: Finless drive or external heatsink installation
All Modes
0: Disabled
1: Enabled for output frequencies below 6 Hz
2: Enabled for the entire frequency range
All Modes
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.
All Modes
0: Disabled
1: Enabled. An alarm is triggered at output currents above 150% of the drives rated current.
All Modes
Enables motor protection if output phase loss occurs.
0: Disabled
1: Enabled
Note: This parameter is available in models CIMR-E4A0930 and 4A1200.
