VFD-F (CURVE).cdr

If you set BB action by this parameter and you also need to disable BB action by thisparameter.VFD-F SeriesThere is a built-in RS-485 serial interface, marked (RJ-11 jack) on the control terminal block.The pins are defined below:1: EV2: GND3: SG-4: SG+5: NC6 1 6: for communicationEach AC drive has a pre-assigned communication address specified by 9-00. Thecomputer then controls each AC drive according to its communication address.AC drive can be setup to communicate on Modbus networks using one of the followingmodes: ASCII (American Standard Code for Information interchange) or RTU (RemoteTerminal Unit). Users can select the desired mode along with the serial port communicationprotocol in 09-04 and 09-05.5Code Description:ASCII mode:Each 8-bit data is the combination of two ASCII characters. For example, a 1-bytedata: 64 Hex, shown as ‘64’ in ASCII, consists of ‘6’ (36Hex) and ‘4’ (34Hex).Character ‘0’ ‘1’ ‘2’ ‘3’ ‘4’ ‘5’ ‘6’ ‘7’ASCII Code 30H 31H 32H 33H 34H 35H 36H 37HCharacter ‘8’ ‘9’ ‘A’ ‘B’ ‘C’ ‘D’ ‘E’ ‘F’ASCII Code 38H 39H 41H 42H 43H 44H 45H 46HRTU mode:Each 8-bit is the combination of two 4-bit hexadecimal characters. For example, 64 Hex.2.
