Synchronous Operation between Modules Section 5-1
5-1 Synchronous Operation between Modules
Sync and ASync Modes
Sync Mode The Coordinator Module and Motion Control Modules are normally set to
operate using the same cycle time, i.e., synchronously. Synchronous opera-
tion is the default setting in the System Setup. With this setting, all Motion
Control Modules synchronize operation with the Coordinator Module cycle
time. This allows synchronous control of up to 8 axes.
ASync Mode The Motion Control Modules can be operated at high-speed in ASync Mode.
Some delays in peripheral servicing may occur, but ASync Mode is useful for
increasing the speed of overall system operation.
