1565 FrctnComp Slip
Friction Compensation Slip
Sets the torque level that will be maintained at very low speed once “break away” has
been achieved. This value should always be set less than the level in P1564 [FrctnComp
Stick]. After the time period set in P1563 [FrctnComp Time], the non-viscous friction will
ramp down to this value.

1566 FrctnComp Rated
Friction Compensation Rated
Sets the torque level that will be output at rated motor speed. The friction compensation
routine assumes a linear viscous component that varies in direct proportion to speed
reference. The 1567 [FrctnComp Out] value will increase with speed and will equal the
level set in this parameter at rated motor speed.

1567 FrctnComp Out
Friction Compensation Output
Displays the torque reference output of the Friction Compensation function. This value is
summed with P660 [SReg Output] and P699 [Inertia Comp Out] in the torque control
section of the drive.
