The Axiom Plus drives support a set of status and fault conditions
that can be displayed on the drive’s seven-segment display. In
addition, any fault will display on the diagnostic screen of the Tol-O-
Motion™ Axiom® setup software whenever a computer is
connected to the drive.
Normal Operation
Whenever the drive is powered, and no fault or status conditions are
present, it will display the letter “d” when disabled or “E” when
enabled. This lets the user know the drive’s status at a glance.
Status Codes
Anytime the drive detects a condition that is not a “fault”, yet not a
normal condition, it will display a flashing three-character code. For
example, “L”— “0” — “1” indicates the drive is enabled and has
reached the CW end of travel limit switch.
Faults
Faults are caused by conditions that make it necessary for the drive
to shut down. When one occurs, the drive disables its power
amplifier output stage and displays the appropriate fault code. A
fault is displayed by flashing “F” followed by a two-digit code. For
example, “F” — “5” — “5” indicates that the maximum allowable
following error has been exceeded.
There are two classes of faults in Tol-O-Matic Axiom series servo
motor drives. The first class are called Fatal Faults. These indicate
that something is seriously wrong with the system and can only be
cleared by removing power from the drive.
The second class of faults are Non-Fatal Faults. These faults are of a
less serious nature. They can be cleared by disabling the drive,
correcting the condition that caused the fault, then enabling the
drive again.
