Delta PLC with Powerflex 525

[ttn121]

Hello I’m trying to control Powerflex 525 with a Delta AS series PLC, I’m using explicit messaging methode, I can read data from Powerflex for example nominal voltage etc, but I can not write or set new value to some parameters for example : ” Commanded Freq b002 ” and ” Drive Status b006 “. If anyone could help with this problem I would really appreciate it. Here are some photos of an example of the code!
