5-3 Output Grouping & Modes
Mode 0 Operation
Description
Output channels in a group assigned to Mode 0 function normally and are not affected
by the corresponding input terminal or group channel.
Details
• MOTION ANDING and OUTPUT ENABLE ANDING can be used with outputs in a
Mode 0 group.
• The machine position for a Mode 0 group can be set through OFFSET programming,
Section 3.
Mode 0 Programming During OUTPUT GROUP programming, group together output channels that should
remain unaffected by Modes, and assign them Mode 0.
Mode 1 Operation
Description Outputs in a group assigned to Mode 1 are always enabled to turn on at their programmed
setpoints. However, when the corresponding input terminal is energized, the machine
position for the group immediately resets to the “Preset” value programmed through
the OFFSET function, Section 3. Once the position is reset, the input terminal will have
no effect until it is turned off and the resolver reaches the leading edge of a pulse pro-
grammed into the corresponding group channel. See Figure 28 for input terminal and
group channel assignments.
Applications This mode can be used to automatically adjust phase relationships between machine
sections. It can also be used in applications where some machine sections run multiple
cycles per resolver revolution.
Details • The group position resets at the leading edge of the input terminal signal, regardless
of how long the terminal is on.
• Once a reset occurs, the input terminal has no
effect until it is de-energized and the leading
edge of a pulse in the corresponding group
channel re-arms the terminal.
• When the position of a group resets, the position
of the corresponding group channel also resets.
• On start-up, the input terminal is armed and
the group position is the same as the value
programmed in SHAFT POSITION, Section 3.
On power-down, the group’s current position
setting will be lost.
• Either edge of a pulse in the group channel can
re-arm the input terminal. If the resolver shaft
is rotating in the forward direction (position is
increasing as shaft rotates) the “on” edge of
the pulse will re-arm the terminal. If the shaft
is rotating in the reverse direction (position
decreasing as shaft rotates), the “off” edge of
the pulse will re-arm the terminal.
• Each program in the controller can have different setpoints for output channels and
the corresponding group channel.
• MOTION ANDING and OUTPUT ENABLE ANDING can be used with outputs in a
Mode 1 group.
