97.18 Signal injection Enables signal injection. A high frequency alternating signal is
injected to the motor at the low speed region to improve the
stability of torque control. Signal injection can be enabled with
different amplitude levels.
Note: Use as low a level as possible that gives satisfactory
performance. Signal injection cannot be applied to
asynchronous motors.
0…4 0 = Signal injection is disabled.
1 = Signal injection is enabled with an amplitude level of 5%.
2 = Signal injection is enabled with an amplitude level of 10%.
3 = Signal injection is enabled with an amplitude level of 15%.
4 = Signal injection is enabled with an amplitude level of 20%.
