Figure 12.80 Frequency Detection 1 Time Chart
Note:
Figure 12.80 shows the result of the configuration when L4-07 = 1 [Speed Agree Detection Selection = Detection Always Enabled] . The
default setting of L4-07 is 0 [No detection during baseblock] . When the speed agreement detection selection is “ No Detection during
Baseblock ” , the terminal is deactivated when the drive output stops.

5: Frequency Detection 2
Setting Value Function Description
5 Frequency Detection 2
The terminal activates when the output frequency is higher than the value of L4-01 [Speed Agree Detection Level] . After the
terminal activates, the terminal stays activated until the output frequency is at the value of L4-01 - L4-02 .
Note:
The detection function operates in the two motor rotation directions. The drive uses the L4-01 value as the forward/reverse detection
level.
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 it is not more than the
value of L4-01 .

6: Drive ready
Setting Value 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 because the
drive has an overvoltage or undervoltage fault during stop
•
When the drive is in Programming Mode and will not accept a Run command
■
7: DC Bus Undervoltage
Setting Value 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 Detection Lvl (Uv1)] . The terminal also turns on when there is a fault with the DC bus voltage.
