How to configure the MODBUS holding registers?

I ordered a EVAL robot kit-1 from STM and im trying to connect the motor to a MODBUS software. I used ICC MODBUS MASTER application. There is a problem with the holding registers. NO OTHER VALUE than 4 for the Target position in degrees (least significant bytes) at 0 address and 9 for the Target position in degrees (most significant bytes) for 2 address is working. Please provide the right target position needed for these addresses so that I can proceed.

Also, please link the source code of the firmware. how to setup a new project in the motor control workbench for the board with SPIN32F0A and all the pin configuration and motor data would also be super helpful.

please help me
