Signal Symbol Terminal Description
AC power supply
L1, L2, L3 TE1
Connect to a 3-phase 200 – 230 V 50/60 Hz or 1-phase 230 V 50/60 Hz (≤750 W) commercial power supply.
L11, L21 TE2
Connect to a 1-phase 200 – 230 V 50/60 Hz commercial power supply. Supply power from the same source as that for L1, L2, and L3. Turn
ON before or simultaneously with L1, L2, and L3. Turn OFF simultaneously with or after L1, L2, and L3.
Motoroutput U,V,W TE1
Connect to the U,V, and W terminals of the motor power supply. The motor will not rotate properly, if an error is made in the phase sequence.
Regenerative brake
resistor, brake unit
P, C, D
TE2
When using an optional regenerative brake resistor in combination with an amplifier in the power range of 350 A or less, always remove the
lead from across the terminals D and P. When using an external brake unit or a regenerative brake resistor in combination with amplifiers in
the power range of 500 A or higher, disconnect the cable connections to the internal brake resistor (refer to the MR-J2S manual). For all ampli-
fiers connect the optional regeneration resistor between P and C. When using the optional regeneration unit with amplifiers in the power range
of 500 A or higher, connect the unit between P and N.
NTE2
Ground PE Chassis
Ground with the motor at one point. Connected to the chassis.
