4.2 Troubleshooting steps
VFD-GATEWAY is not running
•
If gateway web interface is not accessible make sure the VFD-GATEWAY run light is illuminated green
VFD-GATEWAY is not accessible from known EtherNet/IP Address
•
Try the default IP address 192.168.0.10
•
Check Ethernet Connection between PC and VFD-GATEWAY
•
Check EtherNet/IP Address of PC.
•
Finally reset the VFD-GATEWAY by following the Factory reset steps (Refer to factory reset section 4.1)
Modbus connection troubleshooting
:
•
Check Address for each Node
•
Drive baud rate is set to 38.4k baud.
•
Drive parity needs to be set to 8 Even 1
•
Check Modbus wiring (see page 7)
Make sure you use the correct cable
•
Termination resistors are in the correct place in the network
•
In ACS/ACH/ACQ/ACS880 and DCS880 products see 58.07 – Communication Diagnostics (refer to the Drive
manuals in each case)
•
58.08 Receive and 58.09 transmit
•
ACS355 – look at 53.06 – “OK Messages”
•
Use the Data screen in the VFD to see if we are transmitting data.
Drive Communicating but not running:
•
Check Start Stop Speed Reference (refer to drive set up page) for all drives
•
Make sure the control device is sending the correct information see ABB State Machine (refer to state machine
area of the drive manual)
•
Speed reference should follow the ABB speed reference specification (refer to speed reference area)
•
Check the correct drive is selected in the settings screen of the VFD-Manual
•
Use the Data screen in the VFD to see if we are transmitting data.
•
Make sure the Ethernet data mapping is correct for each drive (refer ethernet data section of manual)
Ethernet troubleshooting:
•
Make sure VFD-GATEWAY Ethernet IP address/Subnet mask/Gateway is programed correctly.
•
Make sure Ethernet Scanner device Ethernet IP address/Subnet mask/Gateway is programed correctly.
