5.12.4 Displacement Sensor
Rotary encoder Lineup
Description
Type
2 Phase Encoder Quadrature A/B signal.
SKF Encoder
Quadrature A/B signal - Activates internal pull-up resistors.
Pulse Count
Pulses: The number of pulses is the number of pulses per full
motor revolution (360°).
Positions: Since the controller evaluates each pulse on both
the rising and falling edges, the A and B signals quadruple
the location data, hence the name „quadrature encoder“. To
determine the number of pulses at one full revolution, rotate
the shaft 360° and then divide this number by four and vice
versa.
Pos Pr Meter
Set the number of positions per meter.
Scale
Divide the number of pulses by 2/4/8 etc. If the counter
exceeds 32000 +/-, the scale can be used to adjust the
value within the operating value.
