FX-1PG/FX -1PG PULSE GENERATOR UNIT

• Error can be reset by forcedly turning on/off the
peripheral unit. The input X000 does not have to
be used.
When the data on absence/presence of error and
the error code should be saved even after power
interrupt, use the auxiliary relays or data registers
backed up by the battery.
• The stop command is generally provided in the
PGU, and is also output from the sequence
program in the PC. In such a case, the input X001
is not required.
• In operation which does not require returning to the
home position such as inching operation with a
constant feedrate, the input X006 is not required.
• When which one between the relative and absolute
positions should be used is always determined,
drive the M7 using the M8000 or set the M7 always
to OFF.
• Drive one of the M8 to M12 using the M8000.
If two or more of them are turned
on, operation is disabled. (See
Section 6.4.)
• As the general start command, create an
appropriate sequence using the input X007 to drive
the M8 to M12. (See Section 9.1.)
The time after the FX
command until it generates a pulse is
approximately 10 ms usually. However, 500 ms
maximum is required for the first operation after the
PC starts running or for the first operation after the
BFM#0, #1, #2, #3, #4, #5, #6 or #15 is written.
• The TO instruction is a write instruction from the PC
to the BFM. In the example on the left, the PGU is
connected as a special unit in the position nearest
the main unit.
• In the program below, the start bit for the operation
mode cannot be set to OFF inside the PGU, so
operation from the second time and later cannot be
performed. Correct it as shown in the right.
