Motor connection

General information on motor connection and cable lengths

The motor and the braking resistor (Rb) must be connected to terminal X2 of the frequency inverter via screened
cables which must be connected to the PE potential on both ends with good conductivity. Control, power supply
and motor cables must be laid separately. The limit values of national and international regulations must be met
depending on the application, the motor cable length and modulation frequency.
Frequency inverters ≤ DIC-4-017 and DIC-2-018 with an integrated EMC filter comply with the emission limit val‐
ues of product standard EN 61800-3 for a motor cable length of up to 10 m. Optional filters can be used to meet
any customer-specific requirements.

Pay attention to the following when connecting the motor:
● Parameter identification may not be carried out when the du/dt filter is connected;
● The motor cable length equals the sum of the individual cables for multi-motor operation;
● A du/dt filter must generally be employed when flat cables with screened single conductors are used.
