Precautions Concerning Practical Usage
Methods
Setting the Acceleration/Deceleration to Zero
To initiate the target speed immediately without accelerating or decelerating
(acceleration/deceleration Zero operation = automatic startup operation), the
startup speed and acceleration/deceleration time should both be set to 0 (zero). This
produces pulse output at the target speed, with an acceleration/deceleration time of
0 (zero). Setting the startup speed equal to the target speed results in a set value
error, and the positioning unit will not start.
Cautions when you set position command value to 1 pulse
When you set Position Command value (displacement value) to 1 pulse at E-point
control and P-point control, you have to set starting speed higher than 1pps. If you
set the starting speed to 0 pps, Positioning Unit outputs 1 pulse and stops its
operation.
