Using the Torque Reference as the Mode Switching Condition (Default Setting)
When the torque reference equals or exceeds the torque set for the mode switching level for
torque reference (Pn10C), the speed loop is changed to proportional control.
The default setting for the torque reference level is 200%.
Using the Speed Reference as the Mode Switching Condition
•
Rotary Servomotors
When the speed reference equals or exceeds the speed set for the mode switching level for a
speed reference (Pn10D), the speed loop is changed to proportional control.
•
Linear Servomotors
When the speed reference equals or exceeds the speed set for the mode switching level for a
speed reference (Pn181), the speed loop is changed to proportional control.
Using the Acceleration as the Mode Switching Condition
•
Rotary Servomotors
When the speed reference equals or exceeds the acceleration rate set for the mode switching
level for acceleration (Pn10E), the speed loop is changed to proportional control.
