Refer to L4-01/02: Speed Agreement Detection Level and Detection Width on page 197
for details on setting the detection
width.
Setting 5: Frequency Detection 2
Output closes whenever the output frequency is equal to or above the detection level set in L4-01. The output opens when
the output frequency falls below L4-01 minus the hysteresis set in L4-02.
Status
Description
Open
Output frequency is below L4-01 minus L4-02 or has not exceeded L4-01.
Closed
Output frequency exceeded L4-01.
Note:
The detection works in both forward and reverse. The value of L4-01 will be used as the detection level for both directions.

Setting 6: Drive Ready
Output closes whenever the drive is ready to operate the motor.
Status
Description
Open
During power up, initialization, fault or in Programming Mode (while b1-08 = 0 or 2).
Closed
Drive is ready for operation.
Refer to b1-08: Run Command Selection while in Programming Mode on page 108
for details on the setting of b1-08.
Setting 7: DC Bus Undervoltage
Output closes whenever the DC bus voltage or control circuit power supply drops below the trip level. The undervoltage
trip level is determined by L2-05. A fault in the DC bus charge circuit will also cause the DC Bus Undervoltage output to
close.
Status
Description
Open
DC bus voltage is above the level set to L2-05
Closed
DC bus voltage has fallen below the trip level set to L2-05.
Setting 8: During Baseblock (N.O.)
Output closes to indicate that the drive is in a baseblock state. While Baseblock is executed, output transistors are not
switched and no voltage will be output.
