Fault tracing 39
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 X9, and is
switched on.
Drive status display shows ‘r’:
• The MotiFlex e180 is in firmware recovery mode. This means that it does not boot
fully, and allows Mint WorkBench to download firmware from the Choose
Firmware dialogue.
Mint WorkBench fails to detect the MotiFlex e180:
• Ensure that the MotiFlex e180 is powered and the drive status display is
illuminated (page 37).
• Check that the Ethernet cable is connected between the PC and MotiFlex e180.
Check that the cable is connected to port E3 (on the front panel) and not port E1
or E2.
• Check that the PC's Ethernet port has been correctly configured for TCP/IP
operation, and enabled for use with Mint WorkBench (see Configure the PC
Ethernet adapter on page 22).
• Check that the correct Ethernet adapter has been selected (see Enable the
Ethernet adapter for Mint WorkBench on page 23).
• Check that any PC firewall or security software does not prevent communication
on TCP ports 5000 and 5001, and UDP port 5050. These ports are essential for
communication with the MotiFlex e180.
• Try an alternative cable or different port on the PC.
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).
Cannot communicate with the controller after downloading firmware:
• After firmware download, always power cycle the MotiFlex e180.
