Procedures before Operation of the RD77GF

This chapter describes the procedures before operation of the RD77GF.
1.
Mounting the module
Mount the Simple Motion module to the main base unit or extension base unit.
For details, refer to the following.
MELSEC iQ-R Module Configuration Manual
2.
Wiring
Connect the Simple Motion module to external devices.
3.
Adding the module
Add the RD77GF to the module map of the project using an engineering tool.
4.
Module setting (system parameter)
[When the software version of the Simple Motion module is "Ver.04" or before]
The RD77GF uses the CC-Link IE Field Network synchronous communication function. Therefore, the inter-module
synchronization function needs to be set.
Set the inter-module synchronization in "System parameter" of the engineering tool.
• Set the RD77GF as the synchronization target module in the inter-module synchronization setting.
• Set any of 0.50 ms, 1.00 ms, 2.00 ms, or 4.00 ms as the inter-module synchronous cycle according to the number of
control axes and network device configuration.
A reference of the inter-module synchronization cycle that can be set is shown below. The cycle that can be
set depends on the control and number of link devices. If processing in the Simple Motion module is not
completed within the inter-module synchronization cycle, it may cause the warning "Synchronization cycle
time over" (warning code: 0CC0H), the error "Inter-module synchronization process error" (error code:
2600H), or "Operation cycle time over error" (error code: 193FH), etc.
The following number of setting stations is for the case that 1 to 16 stations are set to the MR-J4-GF (Motion
Mode), and 17 to 120 stations are set to 160 points (RX/RY) and 72 points (RWw/RWr) per station on
average.
• 1 to 4 stations: 0.50 ms (It is recommended to set "[Pr.152] Maximum number of control axes" based on the
number of axes.)
• 5 to 13 stations: 1.00 ms (It is recommended to set "[Pr.152] Maximum number of control axes" based on
the number of axes.)
• 14 to 64 stations: 2.00 ms
• 65 to 120 stations: 4.00 ms
[When the software version of the Simple Motion module is "Ver.05" or later]
Set the inter-module synchronization function as required.
The CC-Link IE Field Network synchronous communication cycle is set to the inter-module synchronization
cycle when using the inter-module synchronization. When not using the inter-module synchronization, it
depends on "[Pr.96] Operation cycle setting".
Adjust the setting cycle depending on the control and number of link devices and stations. If processing in the
Simple Motion module is not completed within the cycle that is set, it may cause the warning "Synchronization
cycle time over" (warning code: 0CC0H), the error "Inter-module synchronization process error" (error code:
2600H), or "Operation cycle time over error" (error code: 193FH), etc.
