Main circuit terminal overview for MR-J2S-60B4 to MR-J2S-700B4
Terminal Signal Description
L1, L2, L3 Main circuit power supply The rated voltage range is 3-phase 200 to 230V AC, 50/60 Hz. Up to 750 W
a 1-phase power supply is possible.
L11, L21 Control circuit power
supply The rated voltage range is 1-phase 200 to 230V AC, 50/60 Hz. Here L11
must be equal in phase to L1 and L21 equal in phase to L2.
N Brake unit option When using the optional brake unit, connect it across the terminals P and N.
Before connecting the optional brake unit, you must disconnect the internal
brake resistor across the terminals P and C.
Do not connect a optional brake unit to the servo amplifier of MR-J2S-350B
or less.
P, C, D Regenerative brake
option/brake unit MR-J2S-350B or less
The terminals P and D are factory-connected. When connecting an optional
regenerative brake, always disconnect the cable connection across P and D.
Connect the optional regenerative brake across the terminals P and C.
Do not connect a optional brake unit to the servo amplifier of MR-J2S-350B
or less.
MR-J2S-500B or more
When connecting an optional regenerative brake or brake unit, always
disconnect the cable connection across P and C of the internal brake
resistor.
Connect the optional regenerative brake across the terminals P and C.
When using the optional brake unit, connect it across the terminals P and N.
U, V, W Servo motor output Connect to the servo motor power supply terminals U, V, W.
PE Protective earth Connect this terminal to the protective earth (PE) terminals of the servo
motor and control box for grounding.
