(3) I/O signal assignments
(* In the table, ON indicates that the applicable bit is “1,” while OFF indicates that the bit is “0.”)
Signal type Bits Symbol Description 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.
4.9 (2)
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.
4.9 (2)
Speed
16-bit
data
-
16-bit integer.
Specify the speed at which to move the actuator.
Designate the unit of 1.0mm/sec or 0.1mm/sec.
The settable range is 0 to 65535.
Unit of measure is selected by Parameter No. 159 FB Half
Direct Mode Speed Unit.
(Example) In the case of the unit of 1.0mm/sec:
To set 254.0 mm/sec, specify “254.”
If a move command is issued by specifying a value
exceeding the maximum speed, an alarm will occur.
4.9 (2)
PLC output
Acceleration/
deceleration
16-bit
data
-
16-bit integer.
Specify the acceleration/deceleration at which to move the
actuator (the acceleration and deceleration will be the same
value).
The setting unit is 0.01 G and the allowable specification
range is 1 to 300.
(Example) To set “0.30 G,” specify “30.”
If a move command is issued by specifying “0” or any value
exceeding the maximum acceleration or deceleration, an
alarm will occur.
