Description
Feedforward Speed 2 Gain
This gain value is equal to the damping speed gain value + Feedforward friction gain
value. The feedforward friction gain allows cancelling the load viscous friction effect
(load viscous friction torque is proportional to axis speed).This feedforward term
allows reducing the following error during the motor acceleration and deceleration
phases.

This object gives the actual axis position. If the position sensor is resolver, then the value is resolver position
(0x3109,0). If the position sensor is encoder, then the value is encoder position (0x3129,0).
The sensor position is defined by object 0x306A,0.
