Operating Instructions, 04/2015, FW V4.7.3, A5E34261542B AB
Parameter
Description
p9700 = D0 hex
SI copy function (factory setting: 0)
Start the SI parameter copy function.
p9701 = DC hex
Confirm data change (factory setting: 0)
Confirm SI Basic parameter change
p0010 = 0
Drive commissioning parameter filter
0: Ready
p0971 = 1
Save parameter
1: Save the drive object (copy from RAM to ROM)
After the inverter has saved the parameters in a non-volatile fashion, then
p0971 = 0.
Checking the connection of digital inputs
The simultaneous connection of digital inputs with a safety function and a "standard" function
may lead to the drive behaving in unexpected ways.
If you control the safety functions in the inverter using digital inputs, you must check whether
these digital inputs are connected to a "standard" function.
Procedure with STARTER
Proceed as follows to check as to whether the safety-related inputs are only used for the
safety functions:
1.
In the project navigator, select the inputs/outputs.
2.
Select the screen for the digital inputs.
