NOTE
• Activation of analog data
The trigger will not start if the trigger starting conditions have already been met when [ Start] is selected. If "Rise" is
selected, the trigger occurs when the set value in "level" is exceeded, and with "Fall", the trigger occurs when the set value
drops to a level lower than "level".
Example: If trigger start condition is "Rise" and the level is set to "3"
If the level is 4 when sampling starts, the trigger will not start. When changed from less than 3 to 3 or more, the trigger
conditions are met and sampling will start.
• If the machine speed is displayed by setting Pr.37 Speed display to a value other than 0
To set the "Output frequency" or "Frequency" as the trigger data, enter the trigger activation machine speed as is to the "level"
column.
For example, if
Pr.37 Speed display is set to "1800" with "Output frequency" as the sampling item, and the trigger is to be
activated at "900", input "900" as is to the "level" column.
Symbol Name Function/description
A Trigger data
Selects the signal that triggers the start of sampling. The trigger signals are as follows.
• Not used
• Analog CH, digital CH (sampling starts if the sampling items meet the conditions)
• Fault (Sampling starts if a fault occurs.)
B Trigger type
Selects the conditions to determine trigger condition satisfaction from rise or fall. (Only appears when
trigger data is set to analog CH or digital CH.)
• Rise
Analog CH: When the value specified by the trigger level is exceeded
Digital CH: When the signal changes from OFF to ON
• Fall
Analog CH: When the value drops to a level lower than the trigger level
Digital CH: When the signal changes from ON to OFF
C Trigger level
Set the threshold to determine trigger condition satisfaction by the analog signal. (Only appears
when the trigger data is set to Analog CH.)
D Trigger position
Set the ratio of sampling data to collect before the trigger conditions are met. (Only appears when
trigger data is set to analog CH, digital CH, or fault.)
E
Col. Mode (Collection
mode)
Set whether the sampling should be continuously operated.
Single: Sampling is performed only once.
Continuous: Sampling is performed continuously.
