3.2 EMC Measures
Preset for EMC: Motor cable
The motor cable is a source of interference and must be positioned carefully.
Use the cables recommended by Phytron. They are tested for EMC safety and are suita-
ble for movement.
The shield of the motor cable must be connected to the BaseUnit and to the motor with
low impedance or flat.

Connect the motor cables without interruption (do not use switches) from the motor to
the device. If a cable must be interrupted, use shielded connections and metal hous-
ings to avoid interferences.

Lay the motor cable at a distance of at least 20 cm from the signal cables. If they are
laid closer together, motor cable and signal wiring must be shielded and grounded.

Use potential equalization cables with suitable cross section when the cables are long.
Potential equalisation cables
Connect the shielding on all sides for protection from interference.
The difference of potential can cause incorrect currents on the shielding and must be
avoided by potential equalization cables.
The TM StepDrive must be operated with protective measure PELV/SELV.
Preset for EMC: Filters
i
If there is no DC/DC power supply unit in the direct vicinity of the ET 200
®
SP unit,
the use of the common-mode rejection filters developed by Phytron may be
necessary. The distance between power supply and TM StepDrive should not ex-
ceed 1 m without filter.
