0 : Stop
The drive follows the frequency reference and stops the motor.
1 : Run at (L4-06 x Last Reference)
The drive continues to operate at the frequency reference value set in L4-06 [FreqReference at Reference Loss].
When you return the external frequency reference value, the drive continues to operate with the frequency
reference.

The setting for L4-08 has an effect:
• When you set detection conditions for oL3 [Overtorque 1], oL3 [Overtorque Detection 1], oL4 [Overtorque 2],
and oL4 [Overtorque Detection 2]:
– L6-01 = 1, 3, 5, 7 [Torque Detection Selection 1 = UL @ Speed Agree]
– L6-04 = 1, 3, 5, 7 [Torque Detection Selection 2 = UL @ Speed Agree]
• When you use speed agreement with DriveWorksEZ.
• When the MFDI terminals set for H1-xx = 75, 76 [Up/Down 2 command] activate.
• When you set H2-xx [MFDO Function Select] to these functions:

Figure 12.122 Detection of Frequency Reference Loss
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the frequency reference as a percentage to continue drive operation after it detects a
frequency reference loss. The value is a percentage of the frequency reference before the drive
detected the loss.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the condition that activates speed detection.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the drive to use the soft starter output frequency or the motor speed (estimation value) for
speed detection.
