Position Control
Set bits to enable various postion control functions.
• bit 1 - Enables position regulator output at parameter
318 [Posit Spd Output]
• bit 2 - Enables integrator operation. Resets integrator
if cleared.
• bit 3 - Holds integrator in present state when set.
• bit 4 - When set reverses polarity of offset parameters.
• bit 5 - When set, permits changing the value of
position offsets without changing actual position.
When cleared, position offset is relative to the
re-referenced value or the latched value upon enable if
re-reference was not performed.
• bit 6 - When set disabling the position regulator
causes all accumulated values to be set to the value in
parameter 762 [Mtr Posit Fdbk]. When cleared
disabling the position regulator causes all accumulated
values to be set to the selected position reference
value.
• bit 10 - When set parameter 758 [Pt-Pt Posit Ref] may
be changed without changing actual position.
• bit 13 - Reverses direction of interpolated position and
speed.
• bit 16 - When set position Watch 1 is enabled. When
cleared parameter 741 [Position Status] bit 8 is cleared.
• bit 17 - When set Position Watch 1 output is set when
parameter 763 [Act Motor Posit] is greater than
parameter 780 [PositDtct1 Stpt]. When cleared
Position Watch 1 output is set when parameter 763
[Act Motor Posit] is less than parameter 763 [Act Motor
Posit] [PositDtct1 Stpt].
• bit 18 - When set position Watch 2 is enabled. When
cleared parameter 741 [Position Status] bit 9 is cleared.
• bit 19 - When set Position Watch 2 output is set when
parameter 763 [Act Motor Posit] is greater than
parameter 781 [Posit Dtct2 Stpt]. When cleared
Position Watch 2 output is set when parameter 763
[Act Motor Posit] is less than parameter 781 [Posit
Dtct2 Stpt].
