(2) Operating Examples for Different Switching Conditions
 Using the Force Reference [Factory Setting]
With this setting, the speed loop is switched to P control when the value of force reference input exceeds the
force set in Pn10C. The factory setting for the force reference detection point is 200% of the rated force.
 Using the Speed Reference
With this setting, the speed loop is switched to P control when the value of speed reference input exceeds the
speed set in Pn181.
 Using Acceleration
With this setting, the speed loop is switched to P control when the speed reference exceeds the acceleration set
in Pn182.
 Using the Position Error
With this setting, the speed loop is switched to P control when the position error exceeds the value set in
Pn10F.
This setting is effective with position control only.
