Please note:
Note
Use only shielded twisted pairs for lines. The shielding must be connected to the
metallic or metallized connector jacket on the controller side. To protect the analog
setpoint signal against low-frequency interference, we recommend that you not
ground the shielding on the drive-unit side.
The cable set supplied as an accessory offers excellent immunity against interfer-
ence.
