CHAPTER 8 - CFW-09 OPTIONS AND ACCESSORIES
MOUNTINGOF THEENCODER
For mounting the encoder on the motor, follow the recommendations below:
Couple the encoder directly to the motor shaft (use a flexible coupling
without torsional flexibility);
Both the shaft and the metallic frame of the encoder must be electrically
isolated from the motor. (min. spacing: 3 mm (0.119 in));
Use high quality flexible couplings to prevent mechanical oscillation or
backlash.
The electrical connection must be made with shielded cable, maintaining a
minimum distance of about 254 mm (10 in) from other wiring (power, control
cables, etc.). If possible, install the encoder cable in a metallic conduit.
At start-up, program Parameter

- type of control - = 4 (vector with
encoder) to operate the motor with speed feedback through incremental
encoder. For more details about Vector Control operation, refer to chapter 5.
Connector XC9 (DB9 - Male)
*
External Power Supply Voltage for encoder: 5 to 15 Vdc, consumption = 40 mA plus consumption of the
encoder.

0 V reference of the Power Supply Voltage.
***
Valid pin position with encoder HS35B models from Dynapar. For other encoder models, check the
correct connection to meet the required sequence.
