4: Frequency Detection 1

Setting Value

Function

Description

4

Frequency Detection 1

The terminal deactivates when the output frequency > “L4-01 [Speed Agree Detection Level] + L4-02 [Speed Agree Detection Width]”. After the terminal deactivates, the terminal stays deactivated until the output frequency is at the value of L4-01.
Note:

  • The detection function operates in the two motor rotation directions. The drive uses the L4-01 value as the forward/reverse detection level.

  • The drive outputs the motor speed status when A1-02 = 3, 7 [CLV, CLV/PM]. It also outputs the motor speed status when A1-02 = 4 and n4-72 = 1.

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 > L4-01 + L4-02.

Note:

Figure 1 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.
