Encoder cable configuration diagram for rotary encoders
• If using a rotary encoder as a scale measurement encoder, use an HK-KT servo motor or HK-MT servo
motor encoder for as the encoder.
• Use a two-wire type encoder cable.
For cables for rotary encoders, refer to "Motor cables/connector sets" and "Encoder cable" in the following manual.

*1 Use a two-wire type encoder cable. A four-wire type encoder cable cannot be used.
*2 When the motor type of the servo motor is "HK-KT_W" or "HK-MT_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.
*3 Use the servo motor in the range not exceeding the maximum servo motor speed described in "Standard specifications list" in the
following manual.
