To maintain immunity to interference, a shielded cable must be used
and the shield attached in the connector housing.
One or several drives/devices can be connected to the SIMOLINK
Encoder. When the SIMOLINK Encoder is operated in conjunction with
one drive/device, the GND signal should be connected in the cable. If
several drives/devices are connected to the SIMOLINK Encoder, the
GND signal should not be connected; it must be noted in this respect
that large deviations in the 0 V (GND) on different drives/devices can
cause disturbances or malfunctions on the RS422 bus.
The signal generator forms three signals, two with a phase
displacement of ± 90° and one as a zero pulse. The pulse/pause ratio
of the two phase-displaced signals is 1:1 in each case. The pulse width
of the zero pulse is ¼ of a period of the phase-displaced signals (pulse
width 90° el.).
