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 the 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.
