(3) I/O signal assignment (* “ON” in the table shows the corresponding bit of “1” and “OFF” shows “0”.)
Signal type Bit Symbol Contents Details
Target
position
32-bit
data
-
32-bit signed integer indicating the current position
Set the target position on the absolute coordinates.
The unit is 0.01mm and settable range is–999999 to
+999999.
(Example) When it is “+25.41mm”, set it as “2541”.
If the value larger than the value (0.2mm) inside the soft
limit for the parameter, the movement would be limited to
the inside the soft limit (0.2mm).
* When the input is performed in hexadecimal notation,
input the negative value using a complement of 2.

32-bit
data
-
32-bit integer
The unit is 0.01mm and settable range is 1 to +999999.
(Example) When it is “25.40mm”, set it as “2540”.
This register value has two meanings depending on the
operation type.
1) In the case of positioning operation, it shows the
allowable range from the target position, that is
regarded as the positioning completion.
2) In the case of pressing operation, it shows the
pressing width value. Specify the normal operation or
pressing operation using the “PUSH” control signal
setting.
4.8 (3)
Speed
32-bit
data
-
32-bit integer
Specify the speed at which to move the actuator.
The unit is 0.01 mm/sec and the settable range is 0 to
999999.
(Example) When it is “25.41mm/sec”, set it as “2541”.
When the movement command is set with the value
bigger than the max. speed, an alarm is issued.

32-bit
data
-
32-bit signed integer indicating the current position
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) When
it is “+25.40mm”, set it as “2540”.
The unit is 0.01mm and the settable 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.
* When the input is performed in hexadecimal notation,
input the negative value using a complement of 2.
