(2) I/O signal assignments for each axis
The I/O signals of each axis consist of eight input words (channels) and eight output words (channels) in the I/O
areas.
z Control signals and status signals are ON/OFF bit signals.
z The target position and current position are 2-word (32-bit) binary data. Although values from -999999 to
+999999 (unit: 0.01 mm) can be handled by the PLC for these items, set position data within the soft stroke
range (0 to the effective stroke) of the applicable actuator.
z Specify the positioning band. The positioning band is a 2-word (32-bit) binary data. For the positioning band,
the PLC can handle values from 1 to +999999 (unit: 0.01 mm).
z The speed is a 1-word (16-bit) binary data. For the specified speed, the PLC can handle values from 0 to
+65535 (unit: 1.0 mm/sec or 0.1 mm/sec). Take note, however, that the set value should not exceed the
maximum speed supported by 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).
Set Value 0 128 255

0% 50% 100%
z The command current is a 2-word (32-bit) binary data (unit: 1 mA).
z The current speed is a 2-word (32-bit) binary data (unit: 0.01 mm/sec).
z The alarm code is a 1-word (16-bit) binary data.
