1 SAFETY INFORMATION
1.1 SAFETY WARNINGS
NOTE!
 Only use the (CFW500-ENC or CFW500-
ENC2) expansion plug-in module with encoder input in CFW500 series WEG inverters.
 We recommend reading the inverter user´s
manual before installing or operating this accessor y.
 This guide contains important information
for the correct understanding and proper operation of this module.
1.2 PRELIMINARY RECOMMENDATIONS
ATTENTION!
 Always disconnect the general power
supply before connecting or disconnecting the accessories on the frequency inverter.
 Wait at least 10 minutes to guarantee
complete de-energization of the inverter.
2 GENERAL INFORMATION
This guide provides instructions for the installation, configuration and operation of the plug-in expansion module for encoder reader input (CFW500-ENC or CFW500-ENC2).
The Plug-in module for encoder has two differential channels, "A" and "B" designed up to 400 kHz incremental encoder reader frequency. Moreover, it has a configurable +5 V or +12 V output supply for quadrature encoder operation.

4 ACCESSORY INSTALLATION
This accessory is easily installed or replaced. For correct installation of the accessory execute the following steps:
Step 1: With the inverter de-energized, remove the front cover of the Inverter (Figure A.1 on page 29).
Step 2: Remove the plug-in module connected to the inverter, if there is any, as in Figure A.1 on page 29.
Step 3: Fit and press the accessory to be installed as indicated in Figure A.1 on page 29 and then assemble the front cover of the inverter.
Step 4: Power up the inverter and check if parameter P0027 shows value 10 (P0027 = 10, for the model CFW500-ENC) or 12 (P0027 = 12, for CFW500-ENC2). If this information is not true, check if the module used is actually the CFW500-ENC or CFW500-ENC2 and repeat steps 1-4.
Step 5: After incremental encoder well installed and connected to the inverter and motor. Verify if the speed shown in P0038 and P0681 is alright.
5 SETTINGS
The CFW500-ENC or CFW500-ENC2, inputs signals specifications match to the Dynapar incremental encoder model HS35B. To use another type of encoder check if the pins and signal sequence are equivalent to the showed in the Figure 2 on page 10.
It is important to follow some recommendations during assembly of the encoder on the motor:
1. The encoder must be coupled directly to the shaft of the motor without torsional flexibility.
2. Both the shaft and metal frame of the encoder must be electrically isolated from the motor (minimum distance 3 mm).
3. Flexible and high quality coupling must be used to avoid mechanic oscillation or backlash.
The Figure 1 on page 7 below shows the encoder assembly of selfventilated and forced ventilated motors.

The location of the DIP switches to select the kind of analog output and input signal can be better viewed in
Figure A.2 on page 30 and Figure A.3 on page 31.
To use the analog inputs and/ or outputs with current signal, switch S1 and related parameters must be set as indicated in Table 3 on page 12. To activate the termination resistors of the RS-485 interface, see Table
4 on page 12. To set the power supply output for the
encoder + VE, see Table 5 on page 12. For further details about the control connections see chapter 3 Installation and Connection of the inverter.
NOTE!
The digital input signal DI5 is allways NPN input instead of P0271 configuration.
