230V FX Series Positioning Drive Reference Manual
Status Indicator Codes
Following is a list of the status indicator codes. The characters in parentheses correspond to
the diagnostic label attached to the front cover of the amplifier.
(.) Serial Control Mode
An illuminated decimal point LED in any mode indicates the drive is in the Serial Control
Mode. While in the Serial Control Mode, motion can only be initiated by ASCII serial
commands sent through the serial interface. This means the I/O lines that are assigned to
initiate motion will not function, but all I/O lines assigned to other functions will operate
normally.
(P) Indexing or Program
When the drive is executing a program or an index, a “P” will be displayed on the status
indicator.
(H) Homing
An “H” will appear on the status indicator when the drive is executing any Home function.
(J) Jogging
When the drive is executing the Jog function a “J” will be displayed on the status indicator.
(E) External Mode
The drive is ready to initiate motion through the serial interface, I/O, or incoming pulses (if
in either of the two pulse modes).
(A) Analog Mode
When the mode select switches are set to either the Analog Torque or Analog Velocity modes,
an “A” will appear. However, if an Initiate Index, Home or Jog Command is received, the
display will change to an “P”, “H”, or “J”, respectively. The display will return to an “A” once
the initiated motion is complete.
Fault Codes
(U) Uninitialized Memory
This occurs when the non-volatile memory of the drive changes and no longer matches the
stored checksum. This can also occur when changing firmware or powering up with a
