Note 1. The built-in regenerative resistor is not provided for the MR-J3-10T (1).
2. For 1-phase 200 to 230VAC, connect the power supply to L
1
, L
2
and leave L
3
open.
There is no L
3
for 1-phase 100 to 120VAC power supply. Refer to section 1.2 for the power supply specification.
3. For the case when 2 stations are occupied. When 1 station is occupied, the point table ends at No.31.
4. Servo amplifiers MR-J3-70T or greater have a cooling fan.
