Functions
To connect the ModBus, connect each Inverter in parallel as below. Connect a termination resistor
separately to avoid signal reflection, since this JX does not incorporate it. Choose a termination re-
sistor according to the impedance characteristics of the cable to be used.
ModBus Setting
Switching from the External OPE to ModuBus
1. Set the parameters using the Digital Operator in accordance with your communication environ-
ment.
2. Shut off the power.
3. Open the connector cover.
4. Insert the communication cable connected to the ModBus bus line.
5. Set S7 the 485/OPE communications selector to "485".
6. Turn on the power and start ModBus communications.
Switching from ModuBus to the External OPE
1. Remove the ModBus communication line from the RJ45 connector of the Inverter while the
Inverter is stopped. Wait 30 seconds to operate the Digital Operator.
2. Set parameter C070 to "02" (OPE) using the Digital Operator and save it.
3. Shut off the power.
4. Set the 485/OPE selector S7 to "OPE" and connect the external OPE to the RJ45 connector.
5. Turn on the power and start external OPE communications.
Note: Be sure to set parameter C070 in advance. Communication protocol will not be changed
merely by switching S7.
