Basic setting
The following explains each item to be set in basic setting.
[Motion CPU Common Parameter] [Basic setting]
Operation cycle
• Set the of motion operation cycle (cycles at which a position command is computed and sent to the servo amplifier).
• The default value is "Default Setting". The operation cycle is set according to the table below based on the number of axes
for servo amplifier set in the servo network setting.
• If the duration of motion operation has exceeded the operation cycle, the "[St.1046] Operation cycle over flag (R: M30054/
Q: M2054)" turns ON. (Page 370 Processing time monitor and check)
• The number of stations capable of connecting to the SSCNET(/H) 1 line is limited based on the motion operation cycle.
Refer to the following for details on restrictions based on the communication types and operation cycles used.
