KA factor

The K_A factor can be used to adapt the current during the acceleration phases. The current increase is calculated as follows.

Current increase in mA = speed difference  x  K_A / 1000

The steeper the speed ramp, the higher the current increase.

This value can be set in index 0x8023:07 "Ka factor (velo./pos.)" (see Fig. Setting the KA factor).
