■ 5: Frequency Detection 2
Setting Function Description
5 Frequency Detection
2
The terminal activates when the output frequency is higher than the setting value of L4-01 [Speed
Agree Detection Level]. After the terminal activates, the terminal stays on until the output
frequency is at the value of L4-01 - L4-02.
Note:
• The motor rotation direction does not have an effect on the detection function. The drive uses the L4-01 value as the forward/reverse
detection level.
• CLV control uses motor speed as the reference.
ON : The output frequency is higher than the value of L4-01.
OFF : The output frequency is less than the value of “L4-01 - L4-02”, or is less than the value of
L4-01.

■ 6: Drive Ready
Setting Function Description
6 Drive Ready
The terminal activates when the drive is ready and running.
The terminal deactivates in these conditions:
• When the power supply is OFF
• During a fault
• When there is problem with the control power supply
• When there is a parameter configuration error and the drive cannot operate although there is a Run command
• When you enter a Run command and it immediately triggers an overvoltage or undervoltage fault
• When the drive is in Programming Mode and will not accept a Run command
■ 7: DC Bus Undervoltage
Setting Function Description
7 DC Bus
Undervoltage
The terminal activates when the DC bus voltage or control circuit power supply is less than the
voltage set with L2-05 [Undervoltage Detect Level (Uv1)]. The terminal also turns on when there is
a fault with the DC bus voltage.
ON : The DC bus voltage is less than the setting value of L2-05.
OFF : The DC bus voltage is more than the setting value of L2-05.
■ 8: During Baseblock (N.O.)
Setting Function Description
8 During Baseblock (N.
O.)
The terminal turns on during baseblock. When the drive is in baseblock, the drive output transistor
stops switching and the drive will not make DC bus voltage.
ON : During baseblock
OFF : The drive is not in baseblock.
