3.4 Buffer Memory Assignment 3.4.2 Details of the buffer memory
(44)CH1 Frequency measurement flag (Un\G1130)
• This memory stores the value indicating whether the module is measuring the frequency or not.
When the module is measuring the frequency, 1
H
is stored. When the module is not measuring the
frequency, 0
H
is stored.
• The stored value is cleared to 0 by turning off and on Operating condition settings batch-change command
(Y01).
(45)CH1 Measured frequency value update flag (Un\G1131)
• This memory stores the value indicating whether CH1 Measured frequency value (Un\G1132, Un\G1133) are
updated or not.
When the memories are updated, 1
H
is stored. When the memories are not updated, 0
H
is stored.
• CH1 Measured frequency value (Un\G1132, Un\G1133) are updated without resetting CH1 Measured
frequency value update flag (Un\G1131).
To check the update status of CH1 Measured frequency value (Un\G1132, Un\G1133) once again, reset CH1
Measured frequency value update flag (Un\G1131) by using CH1 Measured frequency value update flag
reset command (Un\G1120).
If you try to reset it by turning off and on Operating condition settings batch-change command (Y01), not only
the stored value in CH1 Measured frequency value update flag (Un\G1131) but also buffer memories for the
data classification Md1 are cleared to 0. Please note that.
(46)CH1 Measured frequency value (Un\G1132, Un\G1133)
• These memories store a measured frequency value.
• The stored value is cleared to 0 by turning off and on Operating condition settings batch-change command
(Y01).
• The default value is 0.
(47)CH1 Time unit setting (rotation speed measurement) (Un\G1150)
• Use this memory to set a unit of time for the rotation speed measurement.
• The setting value is enabled by turning off and on CH1 Count enable command (Y06).
• The default value is 0
H
: 0.01s.
