APPENDIX 5 Processing Times of the Motion CPU

(Note-1): FEED instruction varies greatly depending on the condition (whether other axes are operating or being stopped).
(Note-2): This processing time varies depending on the simultaneous start command. Use this time merely for reference.
(Note-3): If the servo amplifiers of 9 axes or more are connected to one SSCNET
system, it does not support an operation
cycle of 0.4[ms]. 0.8[ms] is used as the real operation cycle, even if 0.4[ms] is set in the system setting.
