EA180 Series Servo Drive Users Manual 3.2.2 Power connection The power connection methods of servo drives are divided into single-phase and three-phase methods. Single-phase method is only allowed for models with output current of 6.2A or below.
Single-phase power supply connection method (applicable to a rated output current of 6.2 A and below) Single-phase AC 220 V Figure 3-1 Single-phase power supply connection Three-phase power supply connection method (4.8 A and above are applicable) Three-phase AC220V / AC38 0 V Figure 3-2 Three-phase power supply connection 21 Terminal mark Terminal name Terminal function P +, D, C S t External brake b resistor b connection terminal ( c hort circuit connection is between P + and D by default. When he braking capacity is insufficient, please open the circuit etween P+ and D, and connect an external braking resistor etween P+ and C.
SIZE A and SIZE D have no D terminal or short circuit onnection) P+, ⊖ Common DC bus T terminal p he DC bus terminals of the servo drive can be connected in arallel when multiple drives are in operation. U, V, W Servo motor T connection terminal U he connection terminals of the servo motor are connected with , V and W wires of the motor. PE T Grounding t wo grounding terminals are connected to the power supply and he motor grounding terminals.
