Note 1. The indicated value is the rated speed of linear encoder when combined with MR-J4 servo amplifier. It may be different from
the specifications of each manufacturer.
2. The indicated value is the specification value of manufacturer. The encoder cable length between the linear encoder and the
servo amplifier is maximum 30 m.
3. Please select a linear encoder within the range.
4. When using a linear encoder of four-wire type with fully closed loop control, use an MR-J4-(DU)_A_-RJ/MR-J4-(DU)_B_-RJ.
When using a linear encoder of four-wire type with scale measurement function, use an MR-J4-(DU)_B_-RJ.
5. When using a linear encoder of A/B/Z-phase differential output method, use an MR-J4-(DU)_A_-RJ/MR-J4-(DU)_B_-RJ.
6. This can be used with servo amplifier with software version B3 or later.
