FX Series Positioning Controllers
Cautions on command codes
1) Handling of command code 0 (high-speed positioning)
When the speed is set to "0" no processing is performed and the entry is skipped.
Though the speed can be omitted in the cod 00 instruction, it cannot be omitted in the table
method.
2) Handling of command code 72 (interrupt jog feed at two-step speed)
When 72 (interrupt jog feed at two-step speed) is set, two speed commands are required.
Make sure to use two entries.
Table No.0 72
Table No.1 72
Table No.10 72
Table No.11 01
3) Error information
Appropriate error codes are generated in the same way as positioning using instructions.
For the meaning of errors and the troubleshooting procedures, refer to Section 10.
Handling of parameters
The positioning parameters and the I/O control parameters can be written from the PLC.
(The system parameters cannot be changed.)
• When the power is turned ON, the initial values (default values) are set to the parameters.
When the parameter data is changed from the PLC, the corresponding parameters are
changed. When the power is turned OFF, the parameters are returned to the initial values.
Make sure to set the parameters as necessary after the power is turned ON.
• Do with peripherals only for the positioning unit when you change parameter (PARA.50 to
PARA.52) for the absolute position detection function.
("When the power supply is turned on to the positioning unit, the absolute position detection"
is executed. The absolute position detection does not operate normally even if the set value is
written from the Programmable controller in the TO instruction.)
• For the parameter change procedures, refer to section 7.3.6.
Two entries make one positioning operation.
Even if only one entry is set for "72" the next entry (No. 11) is regarded
as the second-step speed of "72".
