3vacon • 30 Descriptions of VACON® option boardsLocal contacts: http://drives.danfoss.com/danfoss-drives/local-contacts/I/O terminals on OPTA5 (coded terminal painted black)NOTE: Encoder inputs are wide range inputs that can be used with encoders using +15V or +24V.Technical data:NOTE: A high pulse frequency combined with a great cable capacitance places a considerable loadon the encoder. Apply therefore as low a voltage as possible for the encoder supply, rather lowerthan 24V. The manufacturer also recommends to place jumper X4 to position +15V, if allowed in thevoltage range specification of the encoder.Table 11.
