Encoder
connection
When connecting the encoders to the inverters, always follow the operating instructions
for the relevant inverter and the wiring diagrams supplied with the encoders!
• Maximum line length (inverter – encoder): 100 m (330 ft) with a cable capacitance ≤
120 nF/km
• Conductor cross section: 0.20 ... 0.5 mm
2
(AWG 20 - 24)
• Use shielded cable with twisted pair conductors and apply shield over large area on
both ends :
– At the encoder in the cable gland or in the encoder plug
– To the inverter on the electronics shield clamp or to the housing of the sub D plug
• Install the encoder cables separately from the power cables, maintaining a distance
of at least 200 mm (8 in).
• Encoder with cable gland: Observe the permitted diameter of the encoder cable to
ensure that the cable gland functions correctly.
