r2489

Act. number of shaft revolutions

P-Group: CONTROL
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 .
