14: User-Set Speed Agree 2
Setting Value Function Description
14 User-Set Speed Agree 2
The terminal activates when the output frequency is in the range of L4-03 [Speed Agree Detection Level(+/-)] ± L4-04 [Speed
Agree Detection Width(+/-)] and in the range of the frequency reference ± L4-04 .
Note:
The detection level set with L4-03 is a signed value. The drive will only detect in one direction.
ON : The output frequency is in the range of “ L4-03
±
L4-04 ” and the range of frequency
reference
±
L4-04 .
OFF : The output frequency is not in the range of “ L4-03
±
L4-04 ” nor the range of frequency
reference
±
L4-04 .

15: Frequency Detection 3
Setting Value Function Description
15 Frequency Detection 3
The terminal deactivates when the output frequency is more than “ L4-03 [Speed Agree Detection Level(+/-)] + L4-04 [Speed
Agree Detection Width(+/-)] ” . After the terminal deactivates, the terminal stays deactivated until the output frequency is at the
value of L4-03 .
Note:
The detection level set with L4-03 is a signed value. The drive will only detect in one direction.
ON : The output frequency is less than the value of L4-03 or it is not more than the value of L4-03
+ L4-04 .
OFF : The output frequency is higher than the value of L4-03 + L4-04 .
Figure 12.18 Example of Frequency Detection 3 (value of L4-03 Is Positive)
Note:
Figure 12.18 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.
