Multi-stage
Position Select
1, 2, and 3
Three Multi-stage Position Select inputs are binary-encoded to select one of eight settings,
P060 to P067. Input [CP1] is the LSB; [CP3] is the MSB. If no position select inputs are
assigned, P060 becomes the default position setting.
The three multi-stage position select inputs [CF1, [CF2], and [CF3] are binary-encoded. When
more than one input changes state to select a position, it is possible that skewing of input
transitions would briefly select undesired intermediate positions. To avoid this problem, a
determination time feature is available. Parameter C169 sets a delay time that applies uniformly
to all three inputs. It operates according to the following process:
• The determination timer is initialized upon an input transition. The transition is not yet
transferred to the output.
• The timer is initialized again if an input transitions before the timer expires.
• When the timer expires, the state of all three position select inputs is transferred to the output
(to generate a new position selection, P060 to P067).
Note that excessively long determination time settings will reduce the overall performance of
the position select inputs.
