(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.
