Vector control
Use C0021 to change the influence of the rotor resistance (C0082)
proportionally:
ƒ Reduce the value in C0021 at an increasing speed (negative values)
ƒ Increase the value in C0021 at a decreasing speed
 Note!
When setting the vector control mode, the slip compensation
(C0021) is automatically set to 0.0 %.
ƒ When you switch back to the V/f characteristic control mode,
the slip compensation must be re-adapted.
If the motor may only rotate in one direction, you can limit the output
voltage generation to one direction of rotation via C0909.
Code Description
C0909 = 1 The motor rotates in both directions
C0909 = 2 Motor rotates clockwise, ”positive direction of rotation”
(View of the motor shaft)
C0909 = 3 Motor rotates counter-clockwise, ”negative direction of rotation”
(View of the motor shaft)
