6.4.9 Action of the Flag concerning Linear Interpolation and Circular
Interpolation
Key Point:
Can be used with C32T2, C28P2, C32T2H and C28P2H only.
Table of flag Allocation
Address Flag conditions The uses of the flag in the program
R903A
Control flag
(CH0)
Turns on during execution of pulse output
instructions that include a circular
interpolation instruction and then maintains
that state during pulse output from CH0.
This flag is the same for instructions F166 to
F176.
Use this to prohibit the simultaneous
execution of other high-speed counter
instructions and pulse output
instructions, and to verify completion
of an action.
R903C
Control flag
(CH2)
Turns on during execution of pulse output
instructions that include a circular
interpolation instruction and then maintains
that state during pulse output from CH2.
This flag is the same for instructions F166 to
F176.
Use this to prohibit the simultaneous
execution of other high-speed counter
instructions and pulse output
instructions, and to verify completion
of an action.
R904E
Control flag
for circular
interpolation
Turns on hen circular interpolation
instruction F176 starts up and maintains
that state until the target value is reached.
When the target value has not been
reached even if the circular interpolation
instruction execution condition is off, that
state is maintained. Use this to prohibit the simultaneous
execution of other high-speed counter
instructions and to verify completion of
a circular interpolation action. When
this flag is on, other positioning
instructions F171 to F176 cannot be
started.
R904F
Confirmation
flag for
overwriting
circular
interpolation
Turns on for one scan when the circular
interpolation instruction F176 starts up.
(The set time is ON time when the
periodical interrupt program is executed.)
When conducting control with the
continuous mode for performing
continuous circular interpolation
actions, use this after circular
interpolation instruction startup when
overwriting the next target value.
Note:
•
When the target value has not been reached and the execution condition is off, circular interpolation
control flag R904E turns on and other positioning instructions F171 to F176 cannot be start up.
•
The above flags vary during scanning.
Example: If the above flags are used for more than one time as input conditions, there may be the
different states in the same scan. Replace with internal relays at the beginning of the program as a
measure.
