OUTPUT
OUTPUT is a static register used to enable and dis-
able and set the polarity and direction of the ABZ/UVW
outputs. See Output Modes, Directions, and Polarities
on page 56 for more information on setting the output
mode.
OUTPUT.uvwpol determines whether the polarity of the
UVW outputs is normal or inverted.
Value
0
1
OUTPUT.uvwpol (0x0109 Bit 4)
Description
Normal UVW polarity
Inverted UVW polarity
OUTPUT.apol determines whether the polarity of the
A output is normal or inverted. OUTPUT.apol also de-
termines the state of the A output when the Z output
is active. See Startup Modes on page 58 for more
information.
Value
0
1
OUTPUT.apol (0x0109 Bit 0)
Description
Normal A polarity
Inverted A polarity
Table 59: A Output Polarity
If OUTPUT.abzen = 0, OUTPUT.apol has no effect.
OUTPUT.bpol determines whether the polarity of the
B output is normal or inverted. OUTPUT.bpol also de-
termines the state of the B output when the Z output
is active. See Startup Modes on page 58 for more
information.
Value
0
1
OUTPUT.bpol (0x0109 Bit 1)
Description
Normal B polarity
Inverted B polarity
Table 60: B Output Polarity
If OUTPUT.abzen = 0, OUTPUT.bpol has no effect.
OUTPUT.zpol determines whether the polarity of the Z
output is normal or inverted.
Value
0
1
OUTPUT.zpol (0x0109 Bit 2)
Description
Normal Z+ polarity (active high)
Inverted Z+ polarity (active low)
Table 61: Z Output Polarity
If OUTPUT.abzen = 0, OUTPUT.zpol has no effect.
OUTPUT.abzdir determines the counting direction of
the AB outputs.
Table 63: UVW Output Polarity
If OUTPUT.uvwen = 0, OUTPUT.uvwpol has no effect.
OUTPUT.uvwdir determines the rotation direction
(phase sequence) of the UVW outputs.
Value
0
1
OUTPUT.uvwdir (0x0109 Bit 5)
Description
Normal UVW phase sequence
Reversed UVW phase sequence
Table 64: UVW Rotation Direction
If OUTPUT.uvwen = 0, OUTPUT.uvwdir has no effect.
OUTPUT.abzen enables or disables the ABZ outputs.
Value
0
1
OUTPUT.abzen (0x0109 Bit 6)
Description
ABZ outputs disabled
ABZ outputs enabled
Table 65: ABZ Output Enable
See Output Modes, Directions, and Polarities on page
56 for more information.
OUTPUT.abzen also determines the internal update
rate of the angle and multi-cycle counter values read
via the SPI port. See Response Packet Formats on
page 32 for more information.
OUTPUT.uvw enables or disables the UVW outputs.
Value
0
1
OUTPUT.uvwen (0x0109 Bit 7)
Description
UVW outputs disabled
UVW outputs enabled
Table 66: UVW Output Enable
Value
0
1
OUTPUT.abzdir (0x0109 Bit 3)
Description
Normal counting direction
Reversed counting direction
Table 62: AB Counting Direction
See Output Modes, Directions, and Polarities on page
56 for more information.
If OUTPUT.abzen = 0, OUTPUT.abzdir has no effect.
