Notch Filter Bandwidth
Default: 0
Settings 0–1000 Hz
A notch filter is a filter that attenuates a signal in a specific frequency band.
The notch filter also slows down the response speed in the frequency band to avoid mechanical
resonance.
The higher the setting value for Pr.11-15, the better the mechanical resonance is suppressed.
The notch filter frequency should be equal to the mechanical frequency resonance.
The notch filter bandwidth is the frequency range in which the notch filter is active.

Forward Motor Torque Limit Quadrant I
11-18
Forward Regenerative Torque Limit Quadrant II
11-19

Reverse Regenerative Torque Limit Quadrant IV
Default: 500
Settings 0–500%
FOCPG & FOC Sensorless mode:
The motor rated current = 100%. The setting values for Pr.11-17–Pr.11-20 compare with Pr.03-
00 = 7, 8, 9, 10. The minimum value of the result after comparing is the torque limit. The diagram
below illustrates the torque limit.
TQCPG and TQC Sensorless mode:
The function of Pr.11-17–Pr.11-20 is the same as FOC; however, in this case, the torque limit
and the torque command executes the output torque limit at the same time. Therefore, the
minimum value between Pr.11-17–11-20 and Pr.06-12 becomes the current output torque limit.
VF, VFPG and SVC mode:
Pr.11-17–Pr.11-20 limit the output current, the percentage base value is the drive’s rated current
