6-1-3 Junction terminal block

POINT
(1) How to use the junction terminal block
Always use the junction terminal block (MR-TB20) with the junction terminal block cable (MR-
J2TBL05M) as a set. A connection example is shown below:
Ground the junction terminal block cable on the junction terminal block side with the standard
accessory cable clamp fitting (AERSBAN-ESET). For the use of the cable clamp fitting, refer to
(3), Section 6-2-6.
(2) Terminal labels
The junction terminal block has three terminal block labels which indicate signal arrangement.
Out of these labels, use the two for MR-J2-A. These two labels are for use in the position
control mode. When the parameter settings of I/O signals have been changed or the position
control mode is switched to the speed or torque control mode, refer to (2) in Section 6-1-2 or (2)
in Section 3-1-2 and apply the accessory signal seals to the labels.
