40 Motor control
Motor control settings.
40.01 Motor noise An optimization setting for balancing between control
performance and motor noise level.
Cyclic Maximizes inverter overloadability. 0
Low noise Minimizes motor noise. 1
Long cable Control performance optimized for long motor cables. 2
40.03 Slip gain Defines the slip gain which is used to improve the estimated
motor slip. 100% means full slip gain; 0% means no slip gain.
The default value is 100%. Other values can be used if a
static speed error is detected despite of the full slip gain.
Example (with nominal load and nominal slip of 40 rpm): A
1000 rpm constant speed reference is given to the drive.
Despite of the full slip gain (= 100%), a manual tachometer
measurement from the motor axis gives a speed value of 998
rpm. The static speed error is 1000 rpm - 998 rpm = 2 rpm. To
compensate the error, the slip gain should be increased. At
the 105% gain value, no static speed error exists (2 rpm / 40
rpm = 5%).
0 … 200% Slip gain. 1 = 1%
