Drive control and features61Load encoder gear functionPositioning uses the measured speed and position of the load. The load encodergear function calculates the actual load position on the basis of the measured motorshaft position.Load encoder gear application examples:The load encoder gear parameters 60.03 LOAD GEAR MUL and 60.04 LOADGEAR DIV are set as follows:Note: The sign of the programmed gear ratio has to match the sign of themechanical gear ratio.M3~Positioning uses the measuredspeed and position of the load. If noencoder is mounted on the loadside, the load encoder gear functionmust be applied in order to calcu-late the actual load position on thebasis of the measured motor shaftposition.This configuration also works withthe estimated position besides en-coder 1.A second encoder (encoder 2)mounted on the load side is used asthe source for the actual positionvalue. (Note: Inverted gear ratio isconsidered when the position con-trol output (speed reference) is pro-duced).If the second encoder is an abso-lute encoder, it must be configuredas encoder 1.This configuration does not workwith the estimated position besidesencoder 1 because the motor gearratio is internally set to 1:1 with theestimated speed.M3~ENCODER 1 LOADGEARMOTOR=60.03 LOAD GEAR MUL60.04 LOAD GEAR DIVLoad speedEncoder 1/2 speed
