*1 The regenerative resistor is not built into the MR-J5-10A_.
*2 Servo amplifiers with the rated output symbol of 70 (MR-J5-70A_) or greater have a cooling fan.
*3 This is for the MR-J5-_A-RJ servo amplifier. The MR-J5-_A servo amplifier does not have a CN2L connector.
*4 To configure an absolute position detection system by using a direct drive motor, the battery is required. To configure the absolute
position detection system by using the HK series servo motor, the battery is not required.
