ENCODER MOUNTING:
Follow the recommendations bellow when mounting the encoder on the motor:
„
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 (3 mm (0.119
in) minimum distance.
„
Use high quality flexible couplings to prevent mechanical oscillation or backlash.
The electrical connections must be made with shielded cable, maintaining a minimum distance of about 25 cm
(10 in) from other wires (power, control cables, etc.). If possible, install the encoder cable in a metallic conduit.
During the commissioning, it is necessary to program the control type, P0202 = 4 (Vector with Encoder), in order
to operate with speed feedback via incremental encoder.
For further details on vector control, see the programming manual available for download on: www.weg.
net .
(1) External encoder power supply: 5 to 15 Vdc. Consumption of 40 mA plus the encoder consumption;
(2)
0 V reference of the power supply voltage;
(3) Connector pinout valid for HS35B Dynapar encoder. For other encoder models, verify the correct connection in order to meet
the required sequence.
