4.8 Serial Communication Parameters500 AddressValue:Parameter 500 Protocol = FC protocol [0]0 - 247 1Parameter 500 Protocol = Metasys N2 [1]1 - 255 1Parameter 500 Protocol = MODBUS RTU [3]1 - 247 1Function:This parameter allows the allocation of an address to eachfrequency converter in a serial communication network.Description of choice:Allocate a unique address to the individual frequencyconverter.If the number of units connected (frequency converters +master) is higher than 31, use a repeater.Parameter 500 Address cannot be selected via the serialcommunication, but must be preset via the control unit.501 BaudrateValue:300 Baud (300 BAUD) [0]600 Baud (600 BAUD) [1]1200 Baud (1200 BAUD) [2]2400 Baud (2400 BAUD) [3]4800 Baud (4800 BAUD) [4]9600 Baud (9600 BAUD) [5]Function:This parameter is for programming the speed at whichdata is transmitted via the serial port. Baud rate is definedas the number of bits transmitted per s.Description of choice:Set the frequency converter's transmission speed at a valuecorresponding to the transmission speed of the master.Parameter 501 Baudrate cannot be selected via the serialport, but must be preset via the operating unit.502 Coasting StopValue:Digital input (DIGITAL INPUT) [0]Serial port (SERIAL PORT) [1]Logic and (LOGIC AND) [2]Logic or (LOGIC OR) [3]Function:Parameters 502-508 allow a selection between controllingthe adjustable frequency drive via the digital inputs and/orvia the serial port.If [1] Serial port is selected, the relevant command can onlybe activated if a command is given via the serial port.In the case of [2] Logic and the function must also beactivated via a digital input.Description of choice:Table 4.18, Table 4.19, Table 4.20, and Table 4.21 show whenthe motor is running and when it is coasting, when eachof the following is selected:• [0] Digital input• [1] Serial port• [2] Logic and or [3] Logic orDig. input Ser. port Function0 0 Coasting0 1 Coasting1 0 Motor running1 1 Motor runningTable 4.18 Function Description for [0] Digital inputDig. input Ser. port Function0 0 Coasting0 1 Motor running1 0 Coasting1 1 Motor runningTable 4.19 Function Description for [1] Serial portDig. input Ser. port Function0 0 Coasting0 1 Motor running1 0 Motor running1 1 Motor runningTable 4.20 Function Description for [2] Logic andDig. input Ser. port Function0 0 Coasting0 1 Coasting1 0 Coasting1 1 Motor runningTable 4.21 Function Description for [3] Logic orNOTICECoasting stop and bit 03 in the control word are active atlogic '0'.503 Quick-stopValue:Digital input (DIGITAL INPUT) [0]Serial port (SERIAL PORT) [1]Logic and (LOGIC AND) [2]Logic or (LOGIC OR) [3]Function:See function description for parameter 502 Coasting stop.Programming Design Guide116 Danfoss A/S © Rev.
