(3) Setting Logical AND Connection
When connecting two or more Units by logical AND connection, set
the logical AND connection preset switch on the Unit that is on the
input side to AND.

Note: 1. A setting error will occur and Unit B will lock out if the logical
AND setting switch on the Unit is set to OFF.
2. Set the logical AND setting switch on Unit A to OFF or the
output of Unit A will not turn ON.
(4) Low-speed detection settings
To set a threshold value of low-speed detection frequency, use low-
speed detection settings switches (one each on the front and back of
the Unit). The Unit operates normally only when the preset values on
both switches agree. When the preset values of both switches do not
agree, an error occurs.

(5) Response performance regarding speed detection
The response time of the entire system regarding speed detection
can be calculated by the following formula:
Ts = Tp + Tf + Tr + Tm
Ts : Response time of the entire system
Tp : Response time of the proximity sensor
Tf : Frequency detection time of G9SX-LM
Tr : Response time of G9SX-LM
Tm : Response time of the machine
• Frequency detection time of G9SX-LM (Tf)
The time taken to detect frequency at the rotation detection input
section of G9SX-LM.
Detection time differs depending on the input frequency.
For details, see the diagram below for the characteristics data.
• Response time of proximity sensor (Tp)
Calculation formula is as follows:
Tp = 1 / F (s)
F : Response frequency of the proximity sensor connected to G9SX-LM
Relationship between input frequency and frequency detection time (Example of characteristics data)
