(2) I/O signal assignments for each axis
An I/O signal of each axis consists of 8 words (16 bytes) of I/O addresses.
z Control signals and status signals are bit ON/OFF signals.
z The target position and current position are both a 2-word (32-bit) binary data. Although values from -999999
to +999999 (unit: 0.01 mm) can be handled by the PLC, set position data within the software stroke range (0
up to the effective stroke length) of the applicable actuator.
z Set a desired positioning band. The positioning band is a 2-word (32-bit) binary data and values from 1 to
+999999 (unit: 0.01 mm) can be handled by the PLC.
z The speed is a 1-word (16-bit) binary data. Although values from 0 to +65535 (unit: 1.0 mm/sec or 0.1
mm/sec) can be handled by the PLC, set a value not exceeding the maximum speed of the applicable actuator.
Parameter No. 159, FB Half Direct Mode Speed Unit, determines the unit of measure.
Parameter No.159 setting value Speed setting unit
0 1.0 mm/sec
1 0.1 mm/sec
z The acceleration/deceleration is a 1-word (16-bit) binary data. Although values from 1 to 300 (unit: 0.01 G) can
be handled by the PLC, set a value not exceeding the maximum acceleration and maximum deceleration of
the applicable actuator.
z The push-current limiting value is a 1-word (16-bit) binary data. Although values from 0 (0%) to 255 (100%)
can be handled by the PLC, set a value within the specifiable range of push-current limiting values of the
applicable actuator (refer to the catalog or operation manual for the actuator).
z The command current is a 2-word (32-bit) binary data (unit: 1 mA).
z The current position is a 2-word (32-bit) binary data (unit: 0.01 mm/sec).
Positive value: The actuator is moving in the direction opposite home. / Negative value: The actuator is moving
in the direction of home.
z The alarm code is a 1-word (16-bit) binary data.
