Outline of table operation

In FX -10PG, the program of positioning control can be produced with a table.
2N
When the table operation is used, continuous operation (multi-speed operation) and position-
to-speed operation (the work is de-/accelerated to stop at a desired position) become possible.
One positioning operation per table can be registered. (The number of tables are 200 points
from No. 0 to 199.)
One table is given four attributes of position information (target address), speed information
(operation speed), m code information and operation information.
The buffer memory of FX
The assignment of the buffer memory and positioning table number is fixed, BFM#100 through
BFM#1299 are assigned to the table numbers of No. 0 through 199. When the positioning data
and operation pattern table operation (BFM#27 b5) are selected to the assigned buffer
memory with TO commands from the PLC, positioning operation is started according to the
written information from the table set with the table start number (BFM#98) if START (BFM#26
b9) is turned ON.
- Position information
The target address is set.
Absolute address and relative address can be set.
- Speed information
The operation speed is set.
During operation, the speed information can be changed and the speed can be
changed with an override.
- m code information
No m code : 1
m code, AFTER mode (ON when positioning complete) : 0 through 999
m code, WITH mode (ON during positioning)
m code during continuous operation
If m code of with mode is instructed to the position-to-speed and continuous operation,
a series of continuous operation is done and m code output is sequentially switched
even though the m code OFF command is input.
(m codes which are previously turned on are automatically turned off.)
-10PG is used as the storage destination of the information.
