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.
Extending the telegram (Page 129)
●
The control sends the scaling value to the inverter in PZD 3.
Procedure
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.
