Setting Value

Function

Description

15

Frequency Detection 3

The terminal deactivates when the output frequency > “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 in L4-03 is a signed value. The drive will only detect in one direction.

  • The drive outputs the motor speed status when A1-02 = 3, 7 [Control Method Selection = CLV, CLV/PM].

ON
The output frequency is less than the value of L4-03 or is not higher than the value of L4-03 + L4-04.
 
OFF
The output frequency is higher than the value of L4-03 + L4-04.
 
Figure 1. Example of Frequency Detection 3 (value of L4-03 Is Positive)
Note:

Figure 1 shows the time chart 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.
