(3) I/O signal assignments
(* In the table, ON indicates that the applicable bit is “1,” while OFF indicates that the bit is “0.”)
Address Bits Symbol Function Details
Target
position
32-bit data -
32-bit signed integer.
Specify the target position as a position in the absolute
coordinate system.
The setting unit is 0.01 mm and the allowable specification range
is -999999 to 999999.
(Example) To set “+25.41 mm,” specify “2541.”
If the entered value exceeds the range between the soft limits
(0.2 mm inside the limits) set by the parameters, the movement
will be limited to the soft limit (0.2 mm inside the limit).
* If target positions are entered as hexadecimals, enter negative
values using 2’s complements.
3.9 (3)
Positioning
band
32-bit data -
32-bit integer.
The setting unit is 0.01 mm and the allowable specification range
is 1 to 999999.
(Example) To set “+25.40 mm,” specify “2540.”
This register has one of two meanings depending on the
operation type.
[1] In positioning operation, this register defines the permissible
range from the target position in which positioning will be
deemed to have completed.
[2] In push-motion operation, this register defines the
push-motion band. Whether to perform normal operation or
push-motion operation is set using the control signal PUSH.
3.9 (3)
Speed 32-bit data -
32-bit integer.
Specify the speed at which to move the actuator.
The setting unit is 1.0 mm/sec and the allowable specification
range is 0 to 999999.
(Example) To set “25.41 mm/sec,” specify “2541.”
If a move command is issued by specifying a value exceeding
the maximum speed, an alarm will occur.
3.9 (3)
PLC output
Zone
boundary+
/zone
boundary-
32-bit data -
32-bit signed integer.
After completion of home return, an effective zone signal can be
output separately from the zone boundaries specified by
parameters.
The status signal PZONE turns ON when the current position is
inside these +/- boundaries.
(Example) To set “+25.40 mm,” specify “2540.”
The setting unit is 0.01 mm and the specification range is
-999999 to 999999.
Enter a value that satisfies the relationship of “Zone boundary+ >
Zone boundary-.”
If this function is not used, enter the same value for both the
positive and negative boundaries.
* If the boundaries are entered as hexadecimals, enter negative
values using 2’s complements.
