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 control 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].
This means that you have interconnected the scaling factor for the ramp-up time with PZD
receive word 3.
2. Set p1139 = 2050[2].
This means that you have interconnected the scaling factor for the ramp-down time with
PZD receive word 3.
The inverter receives the value for scaling the ramp-up and ramp-down times via PZD receive
word 3.
