(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.
3.9 (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.
3.9 (2)
Speed 16-bit data -
16-bit integer.
Specify the speed at which to move the actuator.
The setting unit is 1.0 mm/sec or 0.1 mm/sec and the allowable
specification range is 0 to 65535.
The change of unit is to be conducted in Parameter No. 159 FB
Half Direct Mode Speed Unit.
(Example) 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.
3.9 (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.
