Wiring on the Output Side of Main Circuit
Wiring on the Output Side of Main Circuit
Connecting the Inverter and Motor
Connecting the Inverter and Motor
Connect output terminals U, V, and W to motor lead wires U, V, and W, respectively.
Check that the motor rotates forward with the forward run command. Switch over any two of the
outputterminals to each other and reconnect if the motor rotates in reverse with the forward run command.
Never Connect a Power Supply to Output Terminals
Never Connect a Power Supply to Output Terminals
Never connect a power supply to output terminalsU,V, andW. If voltage is applied to the output
terminals,the internal circuits of the Inverter will be damaged.
Never Short or Ground Output Terminals
Never Short or Ground Output Terminals
If the output terminals are touched with bare hands or the output wires come into contact with the
Invertercasing, an electric shock or grounding will occur. This is extremely hazardous. Do not short
the output
wires.
Do Not Use a Phase Advancing Capacitor or Noise Filter
Do Not Use a Phase Advancing Capacitor or Noise Filter
Never to connect a phase advancing capacitor or LC/RC noise filter to an output circuit. Doing so
may
result in damage to the Inverter or cause other parts to burn.
Do Not Use an Electromagnetic Switch or Magnetic Contactor
Do Not Use an Electromagnetic Switch or Magnetic Contactor
Do not connect an electromagnetic switch or magnetic contactor to an output circuit. If a load is
connectedto the Inverter during operation, a surge current will actuate the overcurrent protective
circuit in the Inverter.
