4.10 Encoder Equivalent Output
The SERVOSTAR provides a motor position output in the form of
quadrature encoder signals eliminating the need for an additional
position feedback device. The outputs are differential line drivers.
There is an associated DC common output (C4: pin 3) that can
connect to your port to keep common mode noise and voltage
spikes minimized for device protection. Because there are normally
differences of potential between your controller and the drive,
connection is recommended (if ground loops occur, disconnect and
retest).
The source of the Encoder Equivalent Output (EEO) signals
depends on the type of motor feedback device:
4.10.1 RESOLVER SYSTEMS
The output signal is developed through the R/D hardware circuitry
for minimal phase lag and has a maximum frequency determined
by the motor speed and R/D limits. It provides a configurable
(ENCOUT) resolution of up to 16384 lines (65536 quad counts) per
revolution of the motor shaft. The placement of the index pulse
(INDEXPOS) can be varied on resolver systems within 360
electrical degrees of the feedback signal. For single-speed
resolvers, this means you can vary the position of this signal over
one mechanical revolution. For multi-speed resolvers, the
mechanical position variation is determined by the pole-pair count
of the resolver (e.g. three-speed resolver gives mechanical
variation of the pulse within 1/3 of a revolution).
