MODIFYING EXISTING CHANNEL LOBE DATA
Select:
NEXT
Selects and displays the next LOBE in sequence.
New Display:
CHA02 F _ _ _ - T_ _ _
The '_' in the FROM and TO fields indicates that no
LOBE data has been stored for this LOBE. If numerical
data is present within the FROM and TO fields, than data
has been previously entered for the LOBE that is
displayed.
Select:
FUNCTION:
Terminates the SET function and returns the user to
FUNCTION select mode where anyone of the PLS-601
functions can be selected.
4.2.4 OFFSET
The OFFSET is a constant, positive adjustment that the CONTROL UNIT adds to the actual
Resolver position to produce the shaft POSITION which is displayed and used by the Control Unit
functions. The OFFSET function allows the user to align the resolver (electrical zero) and machine
(mechanical zero) reference points.
The permissible value of the OFFSET parameter is in the range from 0 to the FULL SCALE
VALUE.
An AUTO ZERO function is implemented via the CLEAR key that will automatically calculate
the offset required to zero the current resolver shaft position. Using this function will electrically
set the position of the resolver to 000 within the position field (P) on the PLS-601 front panel
display.
NOTE:
Changing the OFFSET value causes a corresponding change in the displayed shaft
POSITION, but does not affect the values of the stored LOBE data.
The OFFSET function will display the current resolver shaft position within the ‘P’ data field and
the current resolver shaft rotational speed in RPM within the ‘R’ data field.
