Figure 6-7 Connection example: HTL encoder, bipolar, with reference signal
Use a bipolar connection. The unipolar connection should only be employed when the encoder
type being used does not provide push-pull signals.
6.5.8 Interconnecting optional connections
Depending on the range of options installed, further connections have to be interconnected.
Detailed information about interconnecting these options with the interfaces is provided in the
circuit manual.
6.5.9 Connecting the re-cooling unit to the drive
Connect the cable provided for the cooling unit to the corresponding interfaces on the drive and
the cooling unit. Further details are contained in the circuit diagram of the drive and the re-
cooling unit.
