Note
:
1. Don’t short terminals P24 and COM, otherwise the
control board may be damaged.
2. Please use multi-core shielded cable or multi-strand
cable (above 1mm) to connect the control terminals.
3. When using a shielded cable, the shielded layer’s
end that is nearer to the drive should be connected to
PE.
4. The control cables should be as far away (at least
20cm) as possible from the main circuits and high
voltage cables (including power supply cables, motor
cables, relay cables and cables of contactor). The
cables should be vertical to each other to reduce the
disturbance to minimum.
3.2.4 Onsite Wiring Requirements
To avoid mutual EMI disturbance, the control
cables, power cable and motor cable should be
installed as apart as possible, especially when
they are routed in parallel for rather long distance.
If the signal cable must cross the power cable or
motor cable, keep them at right angle to each
other.

Fig. 3-23 Cable Routing Schematic Diagram
If the section area of the motor cable is too big,
the motor should derate. Refer the drive’s cable
specs in Table 3-2. Since the larger the section
area of cables, the greater their capacitance to
the ground, therefore, the output current should
derate 5% with increasing every category of cable
section area.
Shielded/armored cable: high-frequency
low-impedance shielded cable should be used,
such as woven copper mesh, aluminum mesh or
metal mesh.
The control cable should be shielded, and the
clamps at both ends of the metal mesh should be
connected to the earth terminal of the drive
enclosure.
