230V FX Series Positioning Drive Reference Manual
3. The Suspend Upon Fault may only occur in a situation where Suspends are allowed (i.e.,
programs or indexes). Unlike other Suspend conditions, a Suspend Upon Fault may occur
during the ramp down portion of an index which occurs in a program.
4. When a fault occurs during a Suspend function, the program which was running during
the Suspend is terminated. However, the Suspend remains active following a fault reset.
All suspend functions and rules apply to fault initiated suspends except Run Program on
Suspend, because the drive is faulted. The “Out Of Index” output (Output function #45) is
used to indicate that the motor position is not within the faulted index distance when a
Suspend occurs as a result of a fault. This output will become active if the motor moves past
the end of an index during a Suspend Upon Fault, or is moved backwards before the faulted
position where the Suspend was activated.
Programming
Motion Programs are a series of indexes that have been previously set up that you combine
with other programming steps to create a motion profile. Each motion program provides a
series of movements in conjunction with other machine functions. The movements are used
to perform a particular machine operation.
Multiple programs can be created using PCX software, each designed for a different machine
function. The FX drive is capable of storing up to 32 indexes, 10 motion programs (Ø to 9),
and a maximum of 100 program steps in the non-volatile memory.
The number of available programs and average number of steps per program are directly
related to each other. The memory is set up such that if you require 10 programs (maximum),
each program can have an average of 10 program steps each.
A motion program is created by entering program functions in the order in which they are to
be executed. A motion program is made up of function codes, some of which are listed across
the bottom of the PCX program screen. To see the complete list of available codes when you
are in the lower half of the program screen, press the <F1> key. A pop-up screen will display
all of the function codes.
As you enter steps in a program, the function codes and function data (index numbers,
program numbers, dwell times, etc.) are displayed on the program screen so you can easily
follow the program sequence.
You may use any index or program which you have previously created to build your program.
The example motion program shown in Figure 89: "Motion Program Example" on page 129
could be accomplished with one program; however, two programs have been used to show
the use of the Call Program (P) function. In this example, program numbers 1 and 2 are used
and index numbers 1, 2, 3, 4, and 5 are used.
