Connection of the incremental encoder
Proceed as follows when connecting the incremental encoder:
}
The incremental encoder may be connected via an adapter or directly to the speed
monitor.
}
The incremental encoder on connector X12 monitors axis 1; the incremental encoder
on connector X22 monitors axis 2.
}
Use only shielded cables for all connections
}
0 V from the incremental encoder and speed monitor should always be connected.
}
Position the terminating resistors of the signal lines as close as possible to the speed
monitor input.

6.4.2
Connect incremental encoder to the speed monitor via an adapter
}
The adapter is connected between the incremental encoder and the drive. The output
on the adapter is connected to the female RJ45 connector on the speed monitor.
}
The adapter can also be used without connecting to a drive. The signal lines can then
be terminated directly at the adapter with Z
O
= 120 Ohm.
}
If the signal lines in the drive are already terminated with Z
O
= 120 Ohm, the incre-
mental encoder may no longer be terminated.
}
The signals relevant for the speed monitor are utilised in parallel by the adapter. The in-
formation stated under "Connect incremental encoder signals to the speed monitor" and
in the adapter operating manual must be observed when connecting the supply voltage.
}
Supply only incremental encoder with 5 VDC.
