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