<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) and duty selection (C6-01).
<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).
<43> Regional default settings
Setting 0: Japan (Model code: CIMR-AA A) and Asia (Model code: CIMR-AT A)

0: Ramp to stop. A fault is triggered.
1: Coast to stop. A fault is triggered.
2: Fast Stop. Decelerate to stop using the deceleration time in C1-09. A fault is
triggered.
3: Continue operation. An alarm is triggered.
4: Continue operation at reduced speed as set in L8-19.
Selects the detection of input current phase loss, power supply voltage
imbalance, or main circuit electrolytic capacitor deterioration.
0: Disabled
1: Enabled
0: Disabled
1: Enabled (triggered by a single phase loss)
2: Enabled (triggered when two phases are lost)
0: Disabled
1: Enabled
0: During run only. Fan operates only during run and for L8-11 seconds after
stop.
1: Fan always on. Cooling fan operates whenever the drive is powered up.
Sets a delay time to shut off the cooling fan after the Run command is removed
when L8-10 = 0.
0: No oL2 level reduction below 6 Hz.
1: oL2 level is reduced linearly below 6 Hz. It is halved at 0 Hz.
0: Disabled
1: Enabled
Specifies the frequency reference reduction gain at overheat pre-alarm when L8-
03 = 4.
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.
0: Disabled
1: Enabled
0: IP00 enclosure drive
1: Side-by-Side mounting
2: 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 the drives
rated current.
0: Disabled. L8-55 should be disabled when using a regen converter or an
optional braking unit.
1: Protection enabled.
