■External encoder connector
The following table shows the communication method of the external encoder compatible with the MR-J5W2-_G and MR-
J5W3-_G servo amplifiers.
Operation mode
Linear servo system
*4
Fully closed loop system
*4
Scale measurement function
*1 The MR-J4THCBL03M branch cable is required.
*2 The MR-J4FCCBL03M branch cable is required.
*3 If the external encoder communication method is the four-wire type, the MR-J5W2-_G cannot be used. In that case, use the MR-J5-
_G_-RJ.
*4 Available on servo amplifiers with firmware version A5 or later.
Application
Connect an external safety relay to use the STO function. When
using other safety-sub functions, refer to "FUNCTIONAL SAFETY"
in the following manual.
MR-J5 User's Manual (Function)
Connect the digital I/O signals.
Connect the A-axis servo motor encoder or external encoder.
Connect the B-axis servo motor encoder or external encoder.
Connect the C-axis servo motor encoder or external encoder.
To configure the absolute position detection system by using a
direct drive motor, connect the battery for absolute position data
backup.
