2. Press the Return Key, the Up Key, or the Down Key to cause the Mode 6
indicator to blink.
Mode 6 cannot be selected when pin 3 of the Cam Positioner Unit's rear
panel DIP switch is ON (i.e., when adjustment operation is not permitted).
3. From this point on, follow (3) through (6) of the setting procedure for Mode
3.
The number of the bank to be executed will be displayed in BK, so "BK"
cannot be selected.
When changing the number of the bank to be executed, make the setting
in word n + 1 by means of the user's program or a peripheral device such
as the Programming Console, and then turn bit 00 of word n (the Operation
Flag) from ON to OFF, and then ON again.
The term "origin adjustment" refers to the matching of the resolver origin to
the mechanical origin. For example, if the present cam angle is 130° and if
you want this angle position to match the mechanical origin of 0°, then origin
adjustment can be used.
Origin Adjustment Methods
Either of the methods described below can be used for origin adjustment.
When origin adjustment is executed, "7" will blink three times in "MODE," and
the resolver absolute angle will blink three times in "DATA." When origin
adjustment is finished, the previous display will be restored.
Press the button on the front panel of the Cam Positioner Unit. The origin
adjustment value will then be written to the EEPROM in the Unit.
or Turn the Origin Adjustment Flag (bit 01 of word n) from OFF to ON.
When the origin adjustment has been completed, turn ON the Origin Ad-
justment Completion Flag (bit 05 of word n + 8). This flag will automatically
turn OFF when the Origin Adjustment Flag turns OFF.
Origin adjustment will be written to the RAM in the Unit according to the
Origin Adjustment Flag.
When entering the origin adjustment, turn the EEPROM Write Flag (bit 02
of word n) from OFF to ON. The origin adjustment value will then be written
to EEPROM.
Note Because there is a limit to the number of times that data can be written to
EEPROM (approx. 10,000 times), the second of the two methods described
above is recommended for origin adjustment.
During resolver rotation, origin adjustment will not be effective even if it is exe-
cuted.
If origin adjustment is attempted while the Unit has an error, the origin adjust-
ment will be executed after the error is cleared.
