to TIMED OUTPUTS
Use numeric entry or INC/DEC to change CHANNEL. Use numeric entry to set TIME in
milliseconds.
Description
Any four outputs can be programmed to time out rather than remain on until an OFF
setpoint is reached. This makes the output duration constant regardless of machine
speed. If the OFF setpoint is reached before the specified time has elapsed, the timing
will be aborted and the output will turn off immediately.
Once an output times out, it will not turn on until the next ON setpoint is reached. Each
timed output can have a unique time delay length.
A timed output must be programmed with ON and OFF position setpoints in order for
output timing to take effect.
If the machine is rotating in the reverse direction, timed outputs will energize when the
OFF edge of the pulse occurs.

COMP MODE
Press SEL key to toggle between ONE and L/T. Press ENT to confirm your selection.
Description
Speed Comp Mode determines whether standard or leading/trailing edge speed com-
pensation is in effect. When the Speed Comp Mode is ONE, the same value of speed
comp is used for both leading and trailing edges. When the Speed Comp Mode is “L/T”,
the leading and trailing edges of a pulse may have different values of speed comp.
