■CN2/CN2L
By using CN2L connector, the external encoder of A/B/Z-phase differential output type can be connected. The following table
shows the communication method of the encoder compatible with MR-J5-_G_ and MR-J5-_G_-RJ servo amplifiers.
Operation mode
Linear servo system
*1 The MR-J4THCBL03M branch cable is required.
*2 Connect a thermistor to CN2.
Application
Connect the digital I/O signals.
Connect a servo motor encoder or an external encoder.
Connect the external encoder.
To configure the absolute position detection system by using a
direct drive motor, connect the battery for absolute position data
backup.
*2
Connect the input power supply.
