V/f OLV
Selects the method of torque limit controls during accel/decel.
0: Proportional Control
1: Integral Control
All Modes
An overheat alarm will occur if the heatsink temperature exceeds the level set in L8-02.
All Modes
0: Ramp to stop. A fault is triggered.
1: Coast to stop. A fault is triggered.
2: Emergency Stop. Decelerate to stop using the deceleration ramp in C1-09. A fault is
triggered.
3: Continue operation. An alarm is triggered.
4: Derated operation. Run at L8-19 rate.
All Modes
Selects the detection of input current phase loss, power supply voltage imbalance, or main
circuit electrolytic capacitor deterioration.
0: Disabled
1: Enabled
All Modes
0: Disabled
1: Enabled (triggered by a single phase loss)
2: Enabled (triggered when two phases are lost)
All Modes
0: Disabled
1: Enabled
All Modes
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.
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.
All Modes
0: Disabled
1: Enabled
All Modes
Datermines the factor with which the frequency is reduced when an oH pre-alarm is triggered
and L8-03 is set to 4.
All Modes
0: IP20 enclosure drive
1: Side by Side Installation
2: NEMA Type 1 enclosure drive
3: Finless / Fin Outside
All Modes
0: Disabled
1: Enabled below 6 Hz
2: Enabled in whole speed range
All Modes
Sets the delay time before the Carrier Frequency returns to its normal level
All Modes
Enables or disables an alarm when output current exceeds 150% of drive rated current.
0: Disabled
1: Enabled
All Modes
Sets the amount of time that an output phase loss condition must be present before a fault is
triggered.
