Optional Accessories and Boards
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 .
The function expansion boards EBA and EBB have an encoder signal repeater, isolated and externally powered.
(1)
Power supply voltage 12 Vdc / 220 mA for encoder.
(2) Referenced to ground via 1 μF in parallel with 1 kΩ.
(3) Connector pinout valid for HS35B Dynapar encoder. For other encoder models, verify the correct connection in order to meet
the required sequence.
