Troubleshooting
Cause
Check that control power is connected to the proper pins and
turned on. For connection details, see Connecting the System on
page 12.
Ensure cabling is correct and drive power is not being delivered
through the 15-pin connector.
To energize control power, apply 24-48 VDC to pin 15 and ground
to pin 14.
Ensure that transmit, receive and ground are all connected
properly to the host PC.
To prevent the program from running on power up, use the
Communications Lockup Wizard located on the SMI software
Communications menu.
See IPCTL command, or check DHCP server.
See ETHCTL(100,<value>) command.
Adjust the COM port buffer settings to their lowest values.
Check the serial cable connections and/or replace it.
PSU may be too high-precision and/or undersized for the
application, which causes it to brown-out during motion. Make
moves less aggressive, increase PSU size or change to a linear
unregulated power supply.
To discover the source of the fault, use the Motor View tool located
on the SMI software Tools menu.
Check servo bus voltage. If motor uses the DE power option,
ensure that both drive and control power are connected.
Consider making motion less abrupt with softer tuning
parameters or acceleration profiles.
Motor may be undersized or ambient temperature is too high.
Consider adding heat sinks or forced air cooling to the system.
