All Modes
Selects the detection of input current phase loss, power supply voltage imbalance, or main
circuit electrolytic capacitor deterioration.
0: Disabled
1: Enabled always
2: Enabled during operation
3: Enabled during constant speed
Setting 1 cannot be selected for 600 V class drive models and models CIMR-LF that are
in compliance with IEC/EN 61508 SIL3 Safety Integrity Level 3.
All Modes
When ripple is observed in the DC bus, expansion of the input bias is calculated and becomes
the input phase if the difference between the max and minimum values of the ripple are greater
than L8-06.
Detection Level = 100% = Voltage class ×
All Modes
0: Disabled
1: Enabled (triggered by a single phase loss)
2: Enabled (triggered when two phases are lost)
3: Fault at phase loss at start or when two phases lost mid-operation
Note: Setting 3 is available in the control mode V/f or OLV for drives with software versions
PRG: 7200 or later.
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.)
2: Temperature controlled (Cooling fan operated depending on the temperature of the drives
heatsink.)
All Modes
Sets a delay time to shut off the cooling fan after the Up/Down command is removed when
L8-10 = 0.
All Modes
Enter the ambient temperature. This value adjusts the oL2 detection level.
All Modes
0: No oL2 level reduction below 6 Hz.
1: oL2 level is reduced linearly below 6 Hz. It is halved at 0 Hz.
V/f OLV
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
0: Disabled
1: Enabled
All Modes
0: IP00 enclosure drive
2: IP00 enclosure drive with top protective cover
All Modes
Torque Boost increases the output current limit while decreasing the carrier frequency when the
output current exceeds a certain value.
0: Disabled
3: Enabled
All Modes
Sets the reduced carrier frequency used by the Torque Boost function.
All Modes
0: Disabled. L8-55 should be disabled when using a regen converter or an optional braking unit.
1: Protection enabled.
All Modes
Sets stopping method when a Input phase loss fault (PF) occurs. See parameter L8-05.
0: Ramp to Stop - Decelerate to stop using the deceleration ramp in C1-02.
1: Coast to Stop
2: Fast Stop - Decelerate to stop using the deceleration ramp in C1-09.
3: Alarm only - Drive continues operation.
