Sensor Vector Control

Using sensor vector control with a speed sensor (PG) realizes even more accurate speed and torque
control.
Sensor vector control provides the following control modes.
 Speed control
Sensor vector control, when enabled, automatically uses a speed sensor (PG) as the source of
speed feedback to configure a speed control loop.
It provides speed control at an accuracy of ±0.5 % or less as long as the resolution of the speed
sensor (PG) is sufficient.
This enables the accurate monitoring and follow-up of the line speed in winding control, tension
control, or other applications.
 Position control
In the position control, a speed sensor (PG) can be used as the source of position feedback to
configure a position control loop.
Similar to ordinary servo systems, it realizes a positioning accuracy corresponding to the resolution
of the speed sensor in use. The Positioning Completion Range Setting (P017) is set to ±5 pulses by
default.
The position control mode includes position control functions such as "pulse train position control"
under which the position is controlled based on the pulse input and "absolute position control" under
which the position is controlled to the position reference set inside the inverter.
 Torque control
Sensor vector control supports the direct control of the motor output torque, which is suitable for
press control and press-fit control applications. It also includes the torque limit function that controls
the torque to the torque limit value or less while providing the speed control or position control
function.
