FCN 4 - Negative Speed Comp (continued)
In order to activate Negative Speed Compensation, the
corresponding channel must first be set equal to “0” speed
compensation in FCN 4, and then decremented by pressing
the DEC key. Speed compensation for that channel will then
stay in the negative mode until it is set back to “0” speed
compensation.
Whenever Negative Speed Compensation is programmed,
the speed compensation value shown in the position display
will have a minus (“-”) sign in the left-most digit.
Note:
To restore Positive Speed Compensation set the
compensation value back to 0. Then key in desired amount
of Positive Speed Compensation.

FCN 5 - Timed Outputs
(Setup or Master program enable must be active)
Outputs can be turned off after a specified time duration,
instead of staying on until the off position setpoint is reached.
Any output can be timed, and each timed output can specify
a unique time dwell. This is appropriate for devices which
require a specific output time, regardless of machine speed.
Timed outputs are programmed like standard outputs with
“on” and “off” position setpoints specified. A timed output will
turn on at the specified “on” position setpoint, and will turn
off after the specified time delay
or
when the “off” position
setpoint is reached, whichever occurs first.
If the time out
value is set to zero, the output will not be timed.
If an E9 tdE error message occurs, too many timed outputs
exist for the current time base selected. Either reduce the
number of timed outputs or change the time base being
used. See tb section of FCN 0 programming (page 4-5) for
details.
To calculate output timing, use the following relationships:
RPM x 360 = Degrees per Minute
Degrees per Minute
÷
60 = Degrees per Second
Degrees per Second
÷
1000 = Degrees per msec
Therefore: RPM x .006 = Degrees per msec
Example:
Suppose a timing dwell of 20 msec has been
established. At 1000 RPM, the transducer will rotate:
1000 x .006, or 6
°
per msec
During the 20 msec dwell time, the transducer will rotate
120
°
at 1000 RPM.
