Chapter 4 Running and Commissioning
Based on the command modes and running characteristics, the servo drive supports three
running modes, position control, speed control, and torque control.
In the position control mode, the displacement is determined based on the number of pulses
and the speed is determined based on the input pulse frequency. The position control mode
strictly controls the position and speed, and is often used in the positioning device. It is the
most commonly used mode of the servo drive, applicable to the mechanical arm, mounter,
engraving and milling machine, and computer numerical control (CNC) machine tool.
In the speed control mode, the speed is controlled by the AI setting, DI setting, or
communication setting. It is often used in scenarios with constant speed. For example, for the
analog engraving and milling machine, the host controller uses the position control mode, and
the servo drive uses the speed control mode.
In the torque control mode, the torque is changed by changing the analog setting or the
address value by means of communication. This mode is mainly applied to the winding and
unwinding devices with strict tension requirements, for example, tension control scenarios of
the winding device or ber pulling device. In these scenarios, the torque always changes with
the winding radius so that the tension will not change along with the change of the winding
radius.
