Example
In the following example, the higher-level control sets the ramp-up and ramp-down times of
the inverter via PROFIBUS.
Figure 8-14
Preconditions
● You have commissioned the communication between the inverter and the control system.
● Free telegram 999 has been set in the inverter and in your higher-level control system.
● The controller sends the scaling value to the inverter in PZD 3.
Procedure
To interconnect the scaling of the ramp-up and ramp-down times with PZD receive word 3
from the fieldbus in the inverter, proceed as follows:
1. Set p1138 = 2050[2].
2. Set p1139 = 2050[2].
The inverter receives the value for scaling the ramp-up and ramp-down times via PZD
receive word 3.

This means that you have interconnected the scaling factor for the ramp-up time with
PZD receive word 3.
This means that you have interconnected the scaling factor for the ramp-down time with
PZD receive word 3.
