VLT ® 5000 Series■ Parameters - Serial communication500 Address(BUS ADDRESS)Value:1 - 126 ✭ 1Function:This parameter allows specification of the addressof each frequency converter. This feature is usedin connection with PLC/PC connection.Description of choice:The individual frequency converters can be given anaddress between 1 and 126. The address 0 is usedif a master (PLC or PC) wishes to send a telegramthat is to be received by all frequency convertersconnected to the serial communication port at thesame time. In this case, the frequency converterwill not acknowledge receipt. If the number of unitsconnected (frequency converters + master) exceeds31, a repeater is required. Parameter 500 cannot beselected via the serial communication port.501 Baudrate(BAUDRATE)Value: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 speedat which data is to be transmitted via the serialconnection. Baud rate is defined as the numberof bits transferred per second.Description of choice:The transmission speed of the frequency converteris to be set at a value that corresponds to thetransmission speed of the PLC/PC. Parameter 501cannot be selected via the serial port, RS 485. The datatransmission time proper, which is determined by the setbaud rate, is only part of the total communication time.502 Coasting(COASTING SELECT)503 Quick-stop(Q STOP SELECT)504 DC-brake(DC BRAKE SELECT)505 Start(START SELECT)507 Selection of Setup(SETUP SELECT)508 Selection of speed(PRES.REF. SELECT)Value:Digital input (DIGITAL INPUT) [0]Bus (SERIAL PORT) [1]Logic and (LOGIC AND) [2]✭Logic or (LOGIC OR) [3]Function:Parameters 502-508 allow a choice betweencontrolling the frequency converter via the terminals(digital input) and/or via the bus.If Logic and or Bus is selected, the commandin question can only be activated if transmittedvia the serial communication port. In the caseof Logic and, the command must additionally beactivated via one of the digital inputs.Description of choice:Digital input [0] is selected if the control command inquestion is only to be activated via a digital input.Bus [1] is selected if the control command inquestion is only to be activated via a bit in thecontrol word (serial communication).Logic and [2] is selected if the control commandin question is only to be activated when a signalis transmitted (active signal = 1) via both acontrol word and a digital input.Digital input505-508Bus Controlcommand0 0 00 1 01 0 01 1 1Logic or [3] is selected if the control command inquestion is to be activated when a signal is given (activesignal = 1) either via a control word or via a digital input.✭ = factory setting.
