ASDA Series Application Note Application Examples
March, 2015 3-121
When desire to move the cutter to the target position, motor can operate either at forward or
reverse direction. Users can set up available forward rate or avoid point to plan the operating
direction.
When setting P5-93.BA to 1, the system will determine the operating direction according to the
setting of available forward rate, which is set by P5-95. See Figure 3.8.24 for the description of
available forward rate. Its setting is converted by the proportion when motor runs a cycle. For
example, when available forward rate is set to 25%, if motor exceeds the target position for 1/4
cycles (25/100 = 1/4) at forward direction the motor will search the target position at reverse
direction. In the application, if both forward and reverse directions are allowed, it is suggested to
set the rate to 50%. This setting enables the motor to complete the command with the shortest
distance.
Figure 3.8.24 Setting of available forward rate
If forward and reverse directions are both allowed, but cannot pass the specified position, users
can set up an avoid point. When P5-93.BA = 0, the system will determine if the motor shall run at
forward or reverse direction according to the current position, target position and avoid point. The
position of avoid point can be set up by P5-95. In cutting applications, if desire to move the cutter
when the system stops, users can set the cutting position as the avoid point for avoiding the
cutter cutting the material.
