8 Ripple Compensation
YASKAWA TOEPC710616134G AC Drive L1000A Technical Manual Addendum 73
In Closed Loop control methods, this object provides the actual velocity value derived either from the velocity
sensor or the position sensor. In Open Loop Vector [A1-02 = 2] or V/f [A1-02 = 0] control methods, it is based on
drive internal calculations. The value is given in multiples of 1 mm/s.

8 Ripple Compensation
◆ Overview
Only available for PM CLV control method.
This function is intended for use when compensating n*f torque ripple on the motor shaft.
■ Special Functions
Function Description
Calculation of car
inertia
The total car inertia (J) is calculated as follows:
[System Inertia] = ([S8-08] + [S8-09] + [S8-10] + [S8-11] + [S8-12]/2) * ([o1-20] / 4000)
2
J = [S8-04] + [S8-06] + [S8-07] + [System Inertia]
■ Function Description
Set the Kt value [S8-02] from motor data sheet or motor name plate.
Unit of Kt is Nominal Torque [Nm] / Nominal Current [A].
