4 PROCEDURES BEFORE OPERATIONS
4.2 Procedures before Operation of the RD77GF
11.
Parameter settings in slave devices
Set parameters of the servo amplifier to use. When using the MR-J4-GF, always set the followings.
• Set Function selection C-5 (PC18) to "_ _ 0 _" (Absolute position counter warning: Disabled). (for unlimited length feed)
• Set Function selection T-3 (PT29) to "_ _ _ 1" (Dog detection with on). (To use signals other than servo amplifier as external
input signals.)
In addition, it is recommended to set the following parameter.
• Set Function selection D-4 (PD41) to "_ 1 _ _" (Stroke limit enabling condition selection: Enabled only for home position
return mode).
Set the followings to use the linear servo motor control mode, direct drive motor control mode and fully closed loop control
mode.
*1 When the software version of the Simple Motion module is "Ver.01":
The connection with MR-J4-GF (linear servo motor control mode) is not supported.
If connected, the error "Connection servo amplifier speed unit setting error" (error code: 1CBDH) occurs and the target axis becomes
disconnected.
For details, refer to the following.
CC-Link IE Field Network Interface Servo Amplifier Instruction Manual (Motion Mode)
12.
Test mode
Execute the test operation using an engineering tool.
For details, refer to the following.
MELSEC iQ-R Simple Motion Module User's Manual (Application)

Test operation
Check that the program is correctly carried out as created
Operation mode
Setting
Linear servo motor control mode
• Set the operation mode (PA01) to "_ _ 4 _" (Linear servo motor control mode).
Direct drive motor control mode
• Set the operation mode (PA01) to "_ _ 6 _" (DD motor control mode).
Fully closed loop control mode
• Set the operation mode (PA01) to "_ _ 1 _" (Fully closed loop control mode).
• Set "[Cd.133] Semi/Fully closed loop switching request" to "1: Fully closed loop control". The switching
status of semi closed loop control/fully closed loop control is displayed in "[Md.113] Semi/Fully closed
loop status".
