Displayes the actual number of shaft revolutions since trigger of positioning.

Note:

Positioning ramp down is an open loop control method. So, there might be a difference between the position setpoint and the calculated actual position shown in r2489. That means, it could happen that the setpoint position is already reached, although r2489 displays a different actual position .
