External braking resistor
connection terminal
The default connection between P+ and D is short wiring. When the braking
capacity is insufficient, please open the circuit between P+ and D, and
connect the external braking resistor between P+ and C.
The DC bus terminal of the servo drive can be connected in parallel when
the multiple drives are in operation.
Servo motor
connection terminal
The connecting terminals of the servo motors are connected with U, V and
W of the motor.
EA180-2R8-2□、EA180-5R5-2□ one ground terminal; connect with the two
ground terminals of other power size, power supply and motor ground
terminal.
3.2.3 Power connection
Servo drive power supply wiring method is divided into single-phase and three-phase respectively, single-phase only suitable
for the output current of 7.6A and below models.
Single phase power supply wiring method (rated output current 7.6A and below applicable)
