Control for the Owen frequency drive

The example will be given for the PCHV-2 vector frequency drive.

The parameters to be set:

• 8-01 = 2 (source of control CTW only) default is 0
• 8-02 = 1 (source of CTW is from RS-485)
• 8-04 = 0 (disable comm. timeout)
• 8-30 = 2 (Modbus RTU protocol selection)
• 8-31 = 1 (slaveId)
• 8-32 = 2 (9600 comm. speed) default is 3 (19200)
• 8-33 = 2 (no parity, one stop bit) default is 0 even parity

To save the parameters to EEPROM the 64 (decimal) register should be in 1.
