Parameters 223
22.51 Critical speed
function
Enables/disables the critical speeds function. Also
determines whether the specified ranges are effective in both
rotating directions or not.
See also section Critical speeds/frequencies (page 44).

22.71 Motor
potentiometer
function
Activates and selects the mode of the motor potentiometer.
See section Speed compensated stop (page
76).
Disabled
Disabled Motor potentiometer is disabled and its value set to 0. 0
No. Name/Value Description Def/FbEq16
Bit Name Information
0 Enable 1 = Enable: Critical speeds enabled.
0 = Disable: Critical speeds disabled.
1 Sign mode 1 = Signed: The signs of parameters 22.52…22.57 are taken into
account.
0 = Absolute: Parameters 22.52…22.57 are handled as absolute values.
Each range is effective in both directions of rotation.
