====== 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.
