4.3 Scan Time Definitions
This section explains how to set the scan times.
The scan times are the cycles repeated by Machine Controller to execute the user programs
(high-speed scan program, low-speed scan program) over and over. The MP940 also features a
system scan to enable high-precision servo control.
All three scan times must be set for the MP940: High-speed, low-speed, and system. The scan
time settings are important factors in MP940 operation. Refer to the MP940 Machine Controller
User's Manual: Design and Maintenance (SIEZ-C887-4.1) and be sure that suitable times are
set.
