4.3.2 Encoder emulator output terminal J2
Encoder emulator signal can be supplied both in a unipolar and in a differential way. The
selection between the two ways is carried out by the manufacturer, according to the
configuration ordered.
Differential line-drive configuration
J2/1,2
Channel A differential output
J2/3,4
Channel B differential output
J2/5,6
Channel TOPØ differential output
Unipolar line-drive configuration
J2/1
Channel A unipolar output
J2/3
Channel B unipolar output
J2/5
Channel TOPØ unipolar output
(The three unipolar outputs are referred to
ØD,
J2/6
)
Technical characteristics of the outputs:
Number of pulses/rev.
: programmable resolutions through parameter
P36, EN_RES:
128, 256, 512 and 1024 pulses/rev.
Zero notch
: one pulse/rev. of width programmable through parameter
P37,
TOPØ_W
.
Output voltages
- differential:

= +0.8V max.
Connection of encoder emulator:
To connect encoder emulator, please follow instructions below very carefully. The incorrect
execution of signal connection can cause bad operating or even a failure of the encoder
emulator.
