Notes: 1. When mounting the absolute position storage unit outside a cabinet, be sure to mount the surface A with 4 screws. When mounting the unit inside a cabinet, mounting the surface B with 2 screws is also possible. 2. This is not supported by MR-J4W2-0303B6 and MR-J4-03A6(-RJ). Panel Through Attachment (MR-J4ACN15K, MR-J3ACN) By using the panel through attachment on the servo amplifiers of 11 kW to 22 kW, the heat generating section can be mounted outside a cabinet, enabling to dissipate about 50% of the heat from the unit to outside the cabinet. This allows smaller cabinet size.
