ADI4
As ADI4 does not support acyclic services on the PROFIBUS DP, manual speed setpoint
matching must be performed.
The reference between the speed setpoint set by the NC and the associated output voltage
at the setpoint output of the ADI4 is established (reference voltage = 10 V) via the following
axis-specific machine data.
●
MD32260 $MA_RATED_VELO (rated motor speed) [rev/min]
● MD32250 $MA_RATED_OUTVAL (rated output voltage) [%]

Note
The maximum upper limit for the speed setpoint is predefined in following machine data:
•
MD36210 $MA_CTRLOUT_LIMIT (maximum speed setpoint) [%]
Values greater than 100 % do not make sense in connection with ADI4 because the
DACs of the ADI4 limit the output voltage to 10 V.
Calculation of the motor speed
If the motor speed required for speed setpoint matching is not known directly, it can be
calculated as follows with reference to the required axis velocity (linear axis) or load speed
(rotary axis/spindle):
