(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.
(Examle) 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)
Velocity
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.

/Zone
boundary–
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.
