External braking
resistor connection
terminals
Default connection between D and P +.
When the braking is insufficient, please keep P +, D
circuit open, and connect an external braking resistor
between the P + and C.
P+,
DC bus terminal
DC bus terminal of servo drive. It can be shared when
multi-parallel.
U,V,W
Servo motor
terminals
Connection terminals of the servo motor and they are
connected to U, V, W of the motor
PE
Ground
One ground terminal for EA100-2R8-2A and
EA100-5R5-2A; Two ground terminals for other power
drives. It is connected to the ground terminal of power
supply and the ground terminal of motor.
4.2.2 Power Wiring
Servo drive power connection is divided into 1-phase and 2-phase. 1-phase only for the drives with output current 7.6A and less than 7.6A
1-phase power supply wiring (rated output current
≤
7.6A)
