Fault tracing 123
Power
Drive does not start when applying AC power:
• Check that the motor output phases are not short circuited. The drive trips on a
motor phase short circuit and will not restart unless AC power is removed.
Remove all power from the drive, correct the short circuit and restart the drive.
Communication
Drive status display is off:
• Check that the 24 V DC control circuit supply is correctly connected at X2, and is
switched on.
Drive status display shows ‘r’:
• The MicroFlex e150 is in firmware recovery mode. This means that it cannot boot
fully, so will allow Mint WorkBench to download firmware from the scan controller
dialog.
Mint WorkBench fails to detect the MicroFlex e150:
• Ensure that the MicroFlex e150 is powered and the drive status display is
illuminated (page 121).
• Check that the Ethernet or USB cable is connected between the PC and
MicroFlex e150.
• For Ethernet connections, check that DIP switch 4 is in the ON position to set
standard Ethernet mode. Power cycle the MicroFlex e150 after changing DIP
switch 4. Check that the cable is connected to port E1 (the port nearest the front
panel).
• Check that the PC's Ethernet port has been correctly configured for TCP/IP
operation (see Configuring the TCP/IP connection (optional) on page 93).
• Try an alternative cable or different port on the PC.
• For USB connections, check that the cable is properly connected. Check the USB
connector socket pins for damage or sticking. Check that the USB device driver
has been installed; a ‘ABB USB Motion Product’ device should be listed in
Windows Device Manager, and 'MicroFlex e150' should be listed in Windows
Devices and Printers (Windows 7).
Mint WorkBench
The Spy window does not update:
• The system refresh has been disabled. Go to the Tools, Options menu item,
select the System tab and then choose a System Refresh Rate (500 ms is
recommended).
