4.6 Ground connection
Minimize noise by connecting the shield and/or the connector
housing and/or the frame to ground.
Make sure that ground is not affected by noise.
The connection point to ground can be situated both on the device
side and on user’s side.
The best solution to minimize the interference must be carried out by
the user. You are advised to provide the ground connection as close
as possible to the encoder.
4.7 A, B, 0 output channels
4.8 Index pulse setting input
This encoder provides the zero signal (Index pulse) once per
revolution as relative positioning reference (home position, see the
Figure here above). In this way a unique position can be identified at
a well-known point in the 360° revolution of the encoder shaft.
This input allows to set the point in the revolution at which the 0
pulse will be output. This function is useful, for example, when you
want the zero position of the encoder and the zero mechanical
position of the axis to match.
When you want to set the position of the 0 signal in the revolution
you must send a command via PLC or other controller to the encoder
through the dedicated input. Connect the Index pulse setting input to
0VDC if not used. To set the zero position, connect the Index pulse
setting input to +VDC for 100 µs at least, then discVDC.
Normally voltage must be at 0VDC or floating.
We suggest moving the axis to the desired position, then activate the
Index pulse setting function while the encoder and the mechanical
assembly are in stop.
