(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 0.1mm/sec)
can be handled by the PLC, set a value not exceeding the maximum speed of the applicable actuator.
The setting of unit can be established in Parameter No. 159 FB Half Direct Mode Speed Unit.
Parameter No.159 Setting Value Indicated Speed Unit
0 1.0mm/sec
1 0.1mm/sec
z The acceleration/deceleration is a 1-word (16-bit) binary data. For the acceleration/deceleration, the PLC can
handle values from 1 to 300 (unit: 0.01 G). Take note, however, that the set value should not exceed the
maximum acceleration or maximum deceleration supported by the applicable actuator.
z The push-motion current-limiting value is a 1-word (16-bit) binary data. For the push-motion current-limiting
value, the PLC can handle values from 0 (0%) to 255 (100%). Take note, however, that the setting should be
inside the allowable specification range of push-motion current-limiting values supported by 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.
