Function
Use the PAL analog output port control parameters to assign an analog
output port on the servo module(s) (or processor board for the 9/230) of the
control to one of the PAL analog output control flags ($AOUT00
-$AOUT03). PAL can control up to four analog output ports. Only one
analog output port can be assigned to each PAL analog output port control
parameter. Refer to your PAL reference manual for more details.
PAL-controlled analog output ports must not be defined in AMP as an
analog output port assigned to a fitted axis or a spindle. On the 9/260 and
9/290, PAL cannot control the analog output ports on a servo module (or
processor board for the 9/230) unless there is at least one fitted axis
assigned to that servo module in AMP. On the 9/230, at least one axis must
be fitted to use PAL analog outputs.
Important: For 9/260 and 9/290 controls, the sum total of fitted axes,
spindles, and PAL controlled analog output ports on one servo board, as
defined in AMP, cannot exceed the actual number of output ports on that
servo board. Also, do not include the number of PAL-controlled analog
output ports when determining the value of the parameters Number of
Motors on 1st Board or Number of Motors on 2nd Board.
