5 Operation of Servo System
5.1 Selection and Switching of Control Mode
5.1.1 Selection of control mode
Servo can combine two control modes and switch between them. By switching freely between mode 1
and mode 2 through the / C-SEL signal, more complex control requirements can be satisfied.

When the/C-SEL signal is valid, the servo system will
switch to the mode chosen by P0-02.
Position control is the control of moving to target position through the pulse instruction input in
servo driver from upper device. The position is controlled by the number of input pulses and the speed
is controlled by the frequency of input pulses, which is used in situations where positioning action is
needed. Position instructions can be combined by external pulse input, total number of internal given
position instructions and speed limitation. Position control mode is mainly used in situations requiring
positioning control, such as manipulators, grinders, engraving machines, CNC machine tools and so on.
Speed control refers to the control of mechanical speed through speed instructions. Through
digital, analog voltage or communication given speed instructions, the servo driver can achieve fast and
accurate control of mechanical speed.
The current of servo motor has a linear relationship with the torque, so the control of the current
can realize the control of the torque. Torque control refers to the control of motor output torque through
the torque instruction. Torque instructions can be given by digital, analog voltage or communication.
Torque control mode is mainly used in devices that have strict requirements for material force, such as
winding and unwinding devices. In some tension control situations, the given value of torque should
ensure that material force is not affected by the change of winding radius.
5.1.2 The switch of control mode
Control mode switching refers to the switching between mode 1 and mode 2 through external
input signals when the servo panel displays run.
