YASKAWA MP2300S - Timing at Which Modules Are Synchronized; Operation When High-Speed Scan Cycle Is Changed; Operation When the Mechatrolink Communication Cycle Is Changed; Conditions When the Power Supply Must be Turned off and on

2.2 Basic Module
2.2.5 Built-in SVB Module
2-34
3. Timing At Which Modules Are Synchronized
Modules are automatically synchronized when the power supply is turned OFF and ON again.
4. Operation when High-speed Scan Cycle Is Changed
MECHATROLINK communication with SVB Modules will continue even if the high-speed scan cycle is
changed. However, the speed waveform at execution of interpolation command will be disordered. When chang-
ing the high-speed scan cycle, do so either with the CPU stopped or when motion commands are not being exe-
cuted.
Change the high-speed scan setting and then save the settings to flash memory and turn the power supply OFF
and ON when operation changes from synchronized to asynchronized or from asynchronized to synchronized.
5. Operation When the MECHATROLINK Communication Cycle Is Changed
• Changing the MECHATROLINK communication cycle of the SVB module in the CPU
Synchronization may be lost when a change is made even if synchronization is possible for the high-speed
scan and communication cycle combination. When a change is made, save the settings to flash memory and
then turn the power supply OFF and ON.
• Changing the MECHATROLINK communication cycle of the SVB-01 Module
Operation will be automatically synchronized when a change is made if synchronization is possible for the
high-speed scan and communication cycle combination. It is not necessary to turn the power supply OFF and
ON.
6. Conditions when the Power Supply Must Be Turned OFF and ON
When any of the following operations is performed, save the settings to flash memory and then turn the power
supply OFF and ON.
• After executing a self-configuration command from the MPE720 after turning ON the power supply
• After loading a Module definition after turning ON the power supply
• After changing the communication cycle of the SVB module in the CPU after turning ON the power supply
• After operation changes from synchronized to asynchronized or from asynchronized to synchronized when
the high-speed scan setting is changed
