Hi,

such a behaviour I know if there is not set Bit 10 - management by plc Bit. Check this.

Are both the VFD and s7-300 PLC in the same TIA Portal project?

Are you migrating a classic step 7 project to TIA Portal?

Have you downloaded the PLC project to the s7-300 PLC?

In the portal project, is the VFD connected in the devices and networks pane and the s7-300 configured as the PN master controller?

Screenshots of the hardware configuration for devices/networks in portal would be useful.

Are you using startdrive?

Do you have the latest V16 update installed?

What firmware is installed in the CU320-2PN?
