KA factor

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

Current increase in mA = velocity difference  x  KA / 1000

The steeper the velocity 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).
