Typical symptoms, causes, and actions
Symptoms or message
on the controller
Cause and/or action
HEAD DID NOT
LOAD
The controller failed to load the operating
system into the head.
Check that all cables are connected, and all
devices have power.
If you have connected more than one head,
connected the MRMC system to another local
network, or moved the controller and head
between networks, check that correct LAN
addresses have been entered in the controller.
See
Working with Local Area Networks on page
12.
Check the order in which the devices are
powering up. If you are using an Ethernet
connection to the head, avoid powering the
head from the power output socket on the
controller in order to avoid powering up the
two devices simultaneously (which can cause
problems on small isolated Ethernet networks).
Use an independent power source for each, and
power up the head first. If you are using a
Serial connection to the head, power up the
controller first.

Limits are being

head to oscillate when
reached. The axes have not been zeroed. You must do
this at the beginning of each session just after
you load the head (page 8).
