PHASE REGISTER
Designed for use with System Board, V1.2
only.
Refer to Macro 7.
The register loop takes master and slave
marks in and attempts to align them.
Corrections are applied to the slave axis by
means of trapezoidal move. In this way, the
total error may be corrected within a repeat.
The rate at which the move takes place is set
by the VELOCITY and ACCELERATION
parameters.
Note:
The System Board version is identified by SYSTEM OPTION::VERSION.

Parameter Descriptions
CORRECTIONS
Range: —.
Diagnostic counter of valid mark master/slave pairs.
STATUS
Range: —.
Displays the current mode, RESET or ALIGN. When in RESET, the outputs and counters are
reset. When in ALIGN, a correction is applied after each new pair of marks have arrived,
assuming that the previous correction has been completed.
INCH OFFSET
Range: —.xxxx %
Offset as generated by INCH and MOVE blocks. This is summed with MARK OFFSET to
calculate the real offset. INCH OFFSET is only zeroed with a RESET. INCH OFFSET is
persistent and so its value will be retained on power-down.
ERROR COUNTS
Range: —.
Error, given in slave encoder counts.
ERROR
Range: —.00
Error, given in units (sometimes so small that it does not register, hence ERROR COUNTS)
RESET
Range: FALSE / TRUE
Disables the block and prevents any corrections taking place. Reset also resets the Inch Offset
value leaving.
ENABLE
Range: FALSE / TRUE
When TRUE, corrections are made. When FALSE, corrections are prevented from taking
place, but the diagnostic outputs are computed.
MARK OFFSET
Range: -100.0000 to 100.0000
Offsets the slave mark by this fixed distance. The total of the offset is the sum of the offset
variable and internal Inch Offset variable. The Inch Offset is calculated from the output of the
inch function block and the move function block. Inch offset and offset are both persistent.
SLAVE NOM LENGTH
Range: 0.0000 to 100.0000
The nominal repeat length in units. The nominal length is usually the slave length and is used
to calculate the maximum allowed correction.
