Connect the 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 RJ-45 female 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. 24 V-HTL signals may not be terminated.
CAUTION!
Communication errors may occur if the adapter cable is too long or there
are any external sources of interference. The length of the adapter cable
should be <5 m. Lay the adapter cable separately from any potential
sources of interference, such as drive cables leading to the motor, for ex-
ample.
