Speed Compensation
Menu Path MAIN SCREEN to SETUP MENU to SPEED COMP
Background Some devices such as pneumatic cylinders and glue guns require a fixed amount of
time to perform their function. As a machine speeds up, these devices need to be
actuated earlier in the cycle in order to complete their action at the required time. Speed
compensation automatically advances the On/Off setpoints of specified output channel(s)
as the machine speeds up, maintaining proper synchronization at all speeds. See Sec-
tion 4 for a detailed discussion of speed compensation.
Screens For standard controllers, one value of speed compensation applies to both the ON and
OFF setpoints in a channel The SPEED COMP screen for standard controllers looks
like this:
For units with the “-L” option (Leading /Trailing edge), the ON and OFF edges in a
channel can have different values of speed comp. If SPEED COMP MODE in these
models is set to “One,” the same value will apply to both ON and OFF edges, and the
screen above will show. If SPEED COMP MODE is set to L/T, Leading/Trailing Edge
speed comp is activated, and the following screen appears:

SHAFT POSITION
Purpose Because the PS-6144 is a programmable device, it can be set to display a position of
“zero” at any point in the machine cycle. Usually, the machine is jogged to the begin-
ning of a cycle, and SHAFT POSITION is set to zero at this point. This function elimi-
nates the need to adjust the physical coupling between the machine and resolver in
order to change the displayed machine position.
Screen
Programming Use the INC/DEC keys, or the numeric keys followed by ENT to change shaft position.
• Set SHAFT POSITION before doing any SETPOINT or OFFSET programming.
Software Version
Menu Path MAIN SCREEN to SETUP MENU to SYSTEM INFO
to SOFTWARE VERSION
Purpose The Software Version screen displays the revision number of the firmware contained
within the controller. This information may be useful if the unit needs to be returned for
service.

There are no values that can be changed in this screen.
