1. SUMMARY
(5) Wide variety of positioning control functions
The main functions (such as home position return control, standard mode, and interface mode (sequential
positioning command method)) which are required for any positioning system and the sub functions which
limit and add functions to those controls are supported.
(a) Enhanced home position return control
Additional features of home position return control
Ten home position return methods are provided: dog cradle method, dog method, data set method,
continuous operation to torque method, limit switch combined method, scale home position signal
detection method, limit switch front end method, dog front end method, Z-phase detection method, and
scale home position signal detection method 2. Select an applicable method according to the system.
(b) Wide variety of control methods
Positioning control methods such as positioning control are provided.
1) Independent control of each axis
Position control can be performed independently for each axis at any given timing.
2) Interpolation control
Interpolation controls using multiple axes can be performed.
(2-axis to 4-axis linear interpolation control)
3) Tandem drive
Tandem drive for 2 axes can be performed. In scale home position signal detection method and scale
home position signal detection method 2, the deviation between the 2 axes at home position return
can be compensated.
4) Interface mode
The user program controls the servo amplifier with an arbitrary acceleration/deceleration pattern that
is not supported in standard mode by writing the position command to the position command buffer of
the position board every communication cycle (control cycle).
(c) Continuous processing of multiple positioning data
Multiple positioning data can be processed continuously within one operation start.
(d) Acceleration/deceleration processing
Four acceleration/deceleration processing methods are provided: Linear acceleration/deceleration,
S-curve acceleration/deceleration, start up speed, and smoothing filter.
The acceleration/deceleration curve can be selected according to the machine characteristic.
(6) Supports other axes start function
With the other axes start function, the position board can determine the conditions and automatically start
other axes, and turn on/off output signals. The position board does not go through user program processing
so there are no delays or dispersions. This also lessens the load on the user program.
(7) High maintainability
Maintainability is enhanced in the position board.
(a) Data retention without battery
Parameter data can be stored in the flash ROM inside the position board. This feature allows the
retaining of data without a battery.
(b) Alarm collection function
The alarm details when an alarm occurs are automatically stored in the flash ROM inside the position
board.
Storing the alarm information allows the user to check the alarm from the user program or test tool even
after the position board is powered off or reset.
