Chapter 12 Description of Parameter SettingsC2000-HS
12.1-11-6
 Increase Pr.11-13 to enhance the system stiffness in high-speed steady state, and reduce the
speed transient fluctuation at suddenly loading.
 Set Pr.11-01 correctly to get excellent improvement of the speed response.

ASR Output Low-pass Filter Time
Default: 0.008
Settings 0.000–0.350 sec.
 Use this to set the ASR command filter time.

Notch Filter Depth
Default: 0
Settings 0–20 db

Notch Filter Frequency
Default: 0.00
Settings 0.0–200.0 Hz
 Sets the resonance frequency of mechanical system and suppresses the mechanical system
resonance.
 The higher the setting value for Pr.11-15, the better the mechanical resonance is suppressed.
 The notch filter frequency is the mechanical frequency resonance.

Forward Motor Torque Limit Quadrant I

Forward Regenerative Torque Limit Quadrant II

Reverse Motor Torque Limit Quadrant III

Reverse Regenerative Torque Limit Quadrant IV
Default: 500
Settings 0–500%
 FOCPG & FOC Sensorless mode:
The drive rated current = 100%. The setting value for Pr.11-17–Pr.11-20 is compared with
Pr.03-00 = 7, 8, 9, 10. The minimum of the comparison result is the torque limit. Refer to the
torque limit diagram below.
 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
command limits the output torque. The minimum value between Pr.11-17–11-20 and Pr.06-12
becomes the current output torque limit.
