1 OVERVIEW
(1) Positioning control parameters
There are following seven types as positioning control parameters.
Parameter data can be set and corrected interactively using a peripheral device.
Item Description Reference
1
System
settings Multiple system settings, Motion modules and axis No., etc.
are set. Section
6.1
2
Fixed
parameters
Data by such as the mechanical system are set for every
axis.
They are used for calculation of a command position at the
positioning control.
Section
6.2
3
Servo
parameters
Data by such as the servo amplifier and motor type with the
connected servomotor are set for every axis.
They are set to control the servomotors at the positioning
control.
Section
6.3
4
Home position
return data
Data such as the direction, method and speed of the home
position return used at the positioning control are set for
every axis.
Section
8.5.1
5
JOG operation
data Data such as the JOG speed limit value and parameter
block No. used at the JOG operation are set for every axis. Section
8.7.1
6
Parameter
block
Data such as the acceleration/deceleration time and speed
control value at the positioning control are set up to 16
parameter blocks.
They are set with the Motion program, JOG operation data
and home position return data, and it is used to change
easily the acceleration/deceleration processing
(acceleration/deceleration time and speed limit value) at
the positioning control.
Section
6.4
7
Limit switch
output data
Output device, watch data, ON section, output
enable/disable bit and forced output bit used for the limit
output function for every limit output are set.
Section
8.1.2
(2) Motion program
The positioning control, JOG operation and manual pulse generator operation
are executed in the Motion program. The start request is performed using the
PLC program (S(P).SFCS/SVST instruction).
It comprises a Motion program No., G-code, M-code instruction and positioning
data.
Refer to Chapter 7 for details.
•
Motion program No. ...................... It is specified using the PLC program
(S(P).SFCS/SVST instruction).
•
G-code, M-code instruction .......... It indicates the type of positioning control.
•
Positioning data ............................ It is required to execute the G-code, M-code
instructions. The required data is fixed for
every G-code, M-code instruction.
(3) PLC program
The positioning control by the Motion program can be executed using the Motion
dedicated PLC instruction of PLC program.
Refer to Chapter 4 for details.
