(Note-1): The 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 commands to be started simultaneously. Use this time merely
for reference.
For other sequence program instruction processing times, refer to the ACPU
Programming Manual.
