Software Setup and Operation
Failure to follow safe installation guidelines can cause death or serious injury. Use care
in constructing programs that create a continuous loop condition by “Nesting” programs.
When nesting programs, your program must return to the “Master” program somewhere
in the loop to prevent programs from becoming stacked up in memory.
For example, you initiate Program #1, which uses the “P” function to call Program #2, which
uses the “P” to call Program #3, which uses the “P” function to again call Program #2. This
continuous loop condition could cause the memory to get stacked up, causing the drive to
drop out of the program and return to external mode or register a “Ø” fault on the diagnostic
display.
To avoid this condition, it is recommended that you make all of your program calls from your
original program (Program #1 in this example). Then use the Jump function (J) right after the
“P” function calling Program #3 to jump back to “P” function calling Program #2. This will
allow the amplifier memory (RAM) to clear and the loop to continuously run Program #2 and
#3 from Program #1.
Q Set Maximum Torque Output (%)
This function modifies the “Maximum Torque Output” which is set up in the “Limits” screen.
The maximum Torque Output value is multiplied by the Q value specified. This result is
divided by 200 to obtain the actual torque used during the program. When the program has
completed, the original value is restored. If you use a low value for “Q” (less then 100
percent) you may need to set a high value for following error (F). This will avoid faulting the
drive if it runs into a condition requiring more torque than it is allowed to deliver.
JJump
Before this command can be used in a program, you must assign Input Function #28, “Wait/
Jump Input” to one or more hardware input lines. To select this option, enter “J” in the
program step. Then select one of the Jump options shown in the figure below.
