Encoder cable configuration diagram for rotary encoders
• When using a rotary encoder as the load-side encoder, use an HK-KT servo motor as the encoder.
• Use a two-wire type encoder cable.
• When using an A/B/Z-phase differential output rotary encoder, refer to "A/B/Z-phase differential output type
encoder" in the following manual.
MR-J5 Partner's Encoder User's Manual
For cables for rotary encoders, refer to "Motor cables/connector sets" and "Encoder cable" in the following manual.

1-axis drive unit
The linear encoder can be connected without using an MR-J4FCCBL03M branch cable. In addition, a four-wire type linear
encoder can also be used.
*1 When the motor type of the servo motor is "HK-KT_W", a maximum of 240 V is output from the power cable, and when the motor type is
"HK-KT_4_W", a maximum of 480 V is output. Insulation is therefore required. Apply insulation protection according to the maximum
voltage to U, V, W, and each grounding wire. Do not disconnect the power cable during the insulation protection.
*2 Use the servo motor in the range not exceeding the maximum servo motor speed described in "Standard specifications list" in the
"
