4: Frequency Detection 1
Setting Function
4 Frequency Detection
1
Note:
• The detection function operates regardless of the direction of motor rotation. The value of L4-01 is used as the forward/reverse
detection level.
• When using Closed Loop Vector Control, the motor speed is used as the reference.
ON : The output frequency is less than the value of L4-01 or does not exceed the value of L4-01 +
L4-02.
OFF : The output frequency exceeds the value of L4-01 + L4-02.
Note:
This time chart represents 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 set to No
detection during baseblock, the terminal is off when the drive has cut output.

5: Frequency Detection 2
Setting Function
5 Frequency Detection
2
Note:
• The detection function operates regardless of the direction of motor rotation. The value of L4-01 is used as the forward/reverse
detection level.
• When using Closed Loop Vector Control, the motor speed is used as the reference.
ON : The output frequency exceeds the value of L4-01.
OFF : The output frequency is less than the value of "L4-01 - L4-02," or it does not exceed the
value of L4-01.

V/f CL-V/f OLV CLV AOLV
The terminal turns on when the output frequency is higher than the value of L4-01 [Speed Agree
Detection Level] + L4-02 [Speed Agree Detection Width]. After the terminal turns off, the terminal
continues to remain off until the output frequency reaches the level set with L4-01.
Figure 11.89 Frequency Detection 1 Time Chart
V/f CL-V/f OLV CLV AOLV
The terminal turns on when the output frequency is higher than the setting value of L4-01 [Speed
Agree Detection Level]. After the terminal turns on, the terminal continues to stay on until the
output frequency reaches the value of L4-01 - L4-02.
