Mitsubishi Electric MR-J5 User Manual page 8

*1 Values are taken from manufacturer specifications. When the linear encoder is used with MELSERVO-J5 series servo amplifiers, the
rated speed is the lowest value of either the value indicated in the table or the rated speed of the servo motor.
*2 Values are taken from manufacturer specifications. The length of the encoder cable between the linear encoder and the servo amplifier
should not exceed 30 m.
*3 Select a linear encoder that has a resolution within this range.
*4 When using A/B/Z-phase differential output linear encoders, use the MR-J5-_-RJ_.
*5 When using four-wire type linear encoders in a fully closed loop system, use the MR-J5-_-RJ_. When using four-wire type linear
encoders for the scale measurement function, use the MR-J5-_-RJ_.
The following table shows the servo amplifier connectors used to connect the servo amplifier to a linear encoder.

*1 The MR-J4THCBL03M branch cable is required.
*2 Connect a thermistor to CN2.
*3 The MR-J4FCCBL03M branch cable is required.
*4 If the external encoder communication method is the four-wire type, CN2 cannot be used. Use the MR-J5-_-RJ_.
*5 If the external encoder communication method is the four-wire type, the MR-J5W2-_G_ cannot be used. Use the MR-J5-_G-RJ_.
*6 This operation mode can be used by servo amplifiers with a software version of A5 or later.
