Illustration 8: U/f Characteristic
Table 72: Range:
Min: 0 Hz
Max: 400.0 Hz
Default value: Configuration dependent
4.3.7 1-6* Load Depen. Setting
Parameters for adjusting the load-dependent motor settings.
1-62 Slip Compensation
Default value: 0%
Parameter type: Range
2-setup: All setups
Conversion index: -
Data type: int16
Change during operation: True
Enter the % value for slip compensation to compensate for tolerances in the value of n
M,N
. Slip compensation is calculated automat-
ically, which is based on the nominal motor speed n
M,N
.
Table 73: Range:
Min: -400%
Max: 400%
Default value: 0%
1-63 Slip Compensation Time Constant
Default value: 0.10 s
Parameter type: Range
2-setup: All setups
Conversion index: -2
Data type: u_int16
Change during operation: True
Enter the slip compensation reaction speed. A high value results in slow reaction, and a low value results in quick reaction. If low-
frequency resonance problems arise, use a longer time setting.
Table 74: Range:
Min: 0.05 s
Max: 5.00 s
Default value: 0.10 s
1-64 Resonance Dampening
Default value: 100%
Parameter type: Range
2-setup: All setups
Conversion index: -
Data type: u_int16
Change during operation: True
Enter the resonance damping value. Set parameter 1-64 Resonance Dampening and parameter 1-65 Resonance Dampening Time Con-
stant to help eliminate high-frequency resonance problems. To reduce resonance oscillation, increase the value of parameter 1-64
Resonance Dampening.
