This example shows some basic data exchanges between a Parker AC10 VFD drive and a Parker Interact Xpress XT HMI over Modbus/RTU and an RS485 connection.
See the AC10 Installation Guide for more details on its Modbus/RTU implementation (Chapter 12):
The specific Modbus/RTU settings in the Xpress application are as follows to match up the AC10 defaults pretty closely.
The AC10 Modbus implementation limits 'block reads' to 10 registers or less.
