NORD Drivesystems BU0510 - Manual (Page 8)

POSICON position control for NORD frequency inverters, SK 530E and above
8 Subject to technical alterations BU 0510 GB-3911
2 Encoder connections
The internal zero point of the inverter can be adjusted by specifying an offset value.
A possible reduction ratio between the position measurement system (encoder) and the motor can be taken
into account by the use of transformation and reduction ratios. The motor and the position measurement
system (encoder) do not need to have the same direction of rotation. A negative ratio must be set if the
direction of rotation is different.
2.1 Terminal blocks
The terminal blocks for the control connections and for the encoder differ between the versions and sizes of
the frequency inverter.
