ASDA-B2-F Inspection and Model ExplanationSeptember, 2015 1-711.4 Each Part of the Servo Drive Heat sink:Used to secure servo drive and for heat dissipation. Control Circuit Terminal (L1c、L2c):Used to connect 200 ~ 230 V Ac, 50 / 60 Hz 1-phase / 3-phase V AC supply. Main Circuit Terminal (R, S, T):Used to connect 200 ~ 230 V, 50 / 60 Hz commercial power supply. Servo Motor Output (U, V, W):Used to connect servo motor. Never connect the output terminal to main circuit power.The AC servo drive may be destroyed beyond repair if incorrect cables are connected to theoutput terminals. Regenerative Resistor:(1) When using an external regenerative resistor, connect P⊕ and C to the regenerativeresistor and ensure that the circuit between P⊕ and C is open.(2) When using the internal regenerative resistor, ensure that the circuit between P⊕ and Dis closed and the circuit between P⊕ and C is open CN6: DMCNET Connector: Communication port for DMCNET communication. CN1: I/O Interface: Used to connect external controller (PLC) or control I/O signal. CN2: Encoder Interface: Used to connect encoder of servo motor. CN3: Serial Communication Interface: It is controlled by MODBUS and supports RS-232.It can be connected to controllers. Ground Terminal: Used to connect grounding wire of power supply and servo motor.Please connect it properly to avoid electric shock.
