exPlanation of sCaling/Count frequenCy Command/feedbaCk

When using WEG CFW100 drives, speed/frequency is shown in counts� In order to convert to Hz/ rpm, it is needed to know that the Base Frequency (P403) is equivalent to 8192 (2^13)� Also, the Motor Rated speed (P402) can be scaled using the same method�
Actual Frequency (P681) and Command Frequency (P683) can be calculated using that ratio�
For instance: P681 = 2048(dec)�
Freq = 2048*60�00/8192 = 15�00 Hz
RPM = 2048*1740/8192 = 435�00 rpm
ConneCting PC to CfW100 using automationdireCt Cable usb-485m
An AutomationDirect cable, part number USB-485M, provides a quick and easy method of communicating to a WEG CFW100 AC Drive from a PC which has WEG CFW-WPS software installed.

1 SAFETY INFORMATION
1.1 SAFETY WARNI NGS
NOTE!
Only use the RS485 module (CF W100-C RS485) on WEG CF W100 series inve rter s. It is re commend ed read ing th e CFW100 user ’s manual before installing or operating this acce ssor y. The content of this guide provide s important info rmation for the full under standing and proper oper ation of this module.
1.2 PRE LIMINARY RECOMMENDATIONS
ATTENTION!
Always disconnect the gene ral power supply before connecting or disconnec ting the accessories of the CFW100 fre quency inver ter. Wait for at least 10 minute s for the full discharge of th e inverter.
5 CONFIGURATIONS
The RS485 interf ace connections mu st be done on the conn ector as per Table 1.

The location of the DIP sw itch to select the RS485 network term ination can b e better viewed in Figure A2 and it must be configure as per Table 2. . Figure A3 shows a connection example of the CFW100-CRS 485 accessory to a RS485 network. The connection compli es with the directions of the use r's manual of the Modbus RTU for the CF W100.

ConneCting CommuniCation Cables to CfW100 aC drives
The CFW100-CRS485 drive communication module includes a DIP switch that will switch in a 120Ω
terminating resistor for the RS-485 network.
The CFW100 serial communication port is an RS-485 input. Please note that terminals A(-) and B(+) are shared with the USB connector. CFW100 to CFW100 serial connections can be accomplished with standard RS-485 cable (L19827-1 or similar). RS-232 signals can be converted to RS-485 by using a separate converter (see the FA-ISOCON drawings on page 5–8).

CommuniCation Cable ConneCtionS

Serial Modbus-capable AutomationDirect PLCs can communicate with CFW100 drives which have an optional communication card installed.
Serial Modbus control is easier to accomplish from a PLC that supports dedicated Modbus messaging. [Older PLCs may require programming to construct the Modbus strings.] We recommend PLCs with dedicated Modbus serial commands: CLICK (with RS-485 ports), P1000, P2000, P3000, BRX/Do-more, DirectLogic (DL06 or D2-260). Other PLC-Drive connectivity is possible: Please refer to the “Typical ADC PLC to CFW100 Serial Connectivity Matrix” below.

rS-232C to rS-485 ConverSion

An RS-485 network cable can span up to 1000 meters (4000feet). However, many AutomationDirect PLCs have only RS-232C communication ports and require an FA-ISOCON (RS-232C to RS-422/485 network adapter) in order to make an RS-485 connection.
If an FA-ISOCON module is used, set the module DIP switches as required. Refer to the FA-ISOCON manual for more detailed information.
FA-ISOCON Switch Settings:
S21–S23: OFF, ON, ON (19200 baud)
S24–S27: OFF (Automatic Network Transmit Enable)
Terminate: ON (end of run term resistors)
Bias (2): ON (end of run bias resistors)
1/2 DPX (2): ON (RS-485 TXD/RXD jumpers)
Helpful Hint: Some applications require that the FA-ISOCON baud rate is set faster than the drive/network baud rate.
