12.8 H: Terminal Function Selection
YASKAWA SIEPC71061753C GA500 Technical Manual 657
■ 4: Frequency Detection 1
Setting Value Function Description
4 Frequency Detection 1
The terminal deactivates 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 deactivates, the terminal stays deactivated until the output frequency = 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.
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 is higher than the value of L4-01 + L4-02.
Figure 12.81 Frequency Detection 1 Time Chart
Note:
Figure 12.81 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
