encoder cable
(b) Production of load side encoder cable
Produce the load side encoder cable using MR-EKCBL M-H (10m or less) or MR-ECNM as shown
below. The load side encoder cable can be produced as the length of max. 30m. The following diagram
shows a connecting example of more than 5m to 10m.
Pin layout is one of the following.
