50–59 Reserved
Table 7.7 Description of Bytes 10–59
1) Power scale functions as follows:
0 = Multiply power by 10 to get W.
1 = Multiply power by 100 to get W.
2 = Power (kW).
3 = Multiply power by 10 to get kW.

7.4 Parameter Management (Read/Write)

The PROFINET Module can read parameter values from and
write parameter values to the soft starter. The module
handles 1 parameter at a time.
The device references parameters according to their
position in the soft starter's parameter list.

•
Parameter number 1 corresponds to parameter
1-1 Motor Full Load Current.
•
The VLT
parameters. Parameter 112 corresponds to
parameter 20-6 Pedestal Detect.
CAUTION
UNPREDICTABLE BEHAVIOR
Changing the values in parameter group 20-** Factory
Parameters may cause unpredictable behavior in the soft
starter.
•
Do not change the default values of the
parameters in parameter group 20-** Factory
Parameters.

7.4.1 Output

Use output bytes 2–5 to read or write a parameter to the
soft starter.
Byte Bits Details
2 0–7 Parameter number to read/write.
3 0 Reserved.
1 1 = Read parameter.
