Note
• The system operates as follows when the travel distance to the target position (target address 1) after the
interrupt input (INT0) turns ON is shorter than the travel distance required for a deceleration stop:
a) When the version is earlier than Ver. 1.30
If the system cannot stop at the target position (target address 1) by the setting value of deceleration
time, it passes the 1st target position (target address 1), decelerates, and then stops in the 2nd target
position (target address 1).
b) When the version is Ver. 1.30 or later and "interrupt 1-speed constant quantity feed (constant position
stop mode) shortest allowable stop" is disabled, the system performs in the same way as versions
earlier than Ver. 1.30.
c) When the version is Ver. 1.30 or later and "interrupt 1-speed constant quantity feed (constant position
stop mode) shortest allowable stop" is enabled.
If the system cannot stop at the target position (target address 1) with the setting value of deceleration
time, it stops at the target position (target address 1) using a deceleration time
automatically.
However, if the travel distance to the target position (target address 1) after the interrupt input (INT0)
turns ON is shorter than the travel distance required for a sudden stop, the system passes the 1st
target position (target address 1), decelerates, and then stops at the 2nd target position (target
address 1).
*1. Deceleration time setting value is automatically set between sudden stop deceleration time and
deceleration time.
• After the interrupt input (INT0) turns ON, if the target address change function is executed to change the
target address to an address in the opposite direction from the one already specified, the target address
change function is ignored.
2. Operation speed
The actual operation speed is "operation speed 1 x override setting."
Operation speed 1 can be changed using the operation speed change function except under the following
conditions.
• During deceleration operation
• When the speed change disable during operation signal is ON.
3. Address specification
Specified address are handled as absolute addresses.
(The absolute/relative address specification is ignored.)
4. Rotation Direction
The sign of target address 1 decides the operation direction.
+: Operates in the direction that increases the current value.
-: Operates in the direction that decreases the current value.
