Control mode [A]
The method for driving a servo motor varies depending on each control mode. The characteristics of each control mode are
shown in the following.
Control switching
The control mode can be switched with LOP (Control switching).
Control mode switching by using LOP (Control switching)
LOP (Control switching) enables two control modes to be mutually switched. When switching the position control mode to a
different mode, or when switching any control mode to the position control mode, perform switching at a zero speed state.

Position control mode (P)
The speed can be controlled with the pulses that are inputted to the servo amplifier. [Pr. PA01.0 Control mode selection] can
be operated when set to the initial value "0" (Position control mode).
Set the logic of the positioning module and the command pulse of the servo amplifier as follows.
• Q series/L series/R series positioning module
*1 For Q, L, and R series, the logic means the N-side waveform. Therefore, reverse the input pulse logic of the servo amplifier.
• F series positioning module

Description
Pulse/analog/DI command
Position control mode
P
This is a control mode which operates the servo motor with the input of the
pulse train.
Speed control mode
S
This is a control mode which operates the servo motor with the internal
speed or with the analog speed command.
Torque control mode
T
This is a control mode which operates the servo motor with the analog
torque command.
Position/speed control switching
mode
P/S
This is a control mode which performs switching between the position
control and speed control with the input device.
Speed/torque control switching
mode
S/T
This is a control mode which performs switching between the speed
control and torque control with the input device.
Torque/position control switching
mode
T/P
This is a control mode which performs switching between the torque
control and position control with the input device.
