136 Set Motor Encoder
Interpolation
UINT 2 The amount of interpolation to be used with sine/
cosine encoders. For example, if the interpolation
is set to x256, the drive will interpolate 256
counts for every 1/4 line of the input sinusoid.
Valid values are:
4 = x4 (default)
8 = x8
16 = x16
32 = x32
64 = x64
128 = x128
256 = x256
512 = x512
1024 = x1024
137 Set Motor Encoder
Polarity
USINT 1 Select the motor encoder's polarity.
0 = Positive (default) - Turning the motor in a
clockwise direction (as viewed from the shaft
end) increases the feedback position (in counts).
1 = Negative - turning the motor in a clockwise
direction (as viewed from the shaft end)
decreases the feedback position (in counts).
138 Set Motor Encoder
Filter
USINT 1 Select the state of the motor encoder filer. The
filter reduces the upper limit of the rate at which
feedback pulses will be recognized. You may
need to enable feedback in a noisy environment,
or when a long encoder cable is used.
0 = Disable (default)
1 = Enable
139 Set Master Encoder
Polarity
USINT 1 Select the master encoder's polarity.
0 = Positive (default) - Turning the motor in a
clockwise direction (as viewed from the shaft
end) increases the feedback position (in counts).
1 = Negative
140 Set Master Encoder
Filter
USINT 1 Select the state of the master encoder filter. The
filter reduces the upper limit of the rate at which
feedback pulses will be recognized. You may
need to enable feedback in a noisy environment,
or when a long encoder cable is used.
0 = Disable (default)
1 = Enable
