Supply Cable
•
Do not connect the AC supply cable to the output terminals U/V/W of HD3Z.
•
Do not connect the phase-shifting capacitors to the output circuit.
•
Ensure that AC supply voltage is the same as rated input voltage of HD3Z.
Refer to section 4.2 Peripheral Accessories Selection, page 11 for power cable selection.
Motor Connection
Refer to section 4.2 Peripheral Accessories Selection, page 11 for motor cable selection.
The longer cable between the controller and the motor is, the higher frequency leakage current will be,
causing the controller output current to increase as well. This may affect peripheral devices.
When the cable length is longer than 100 meters, it is recommended to install AC output reactor and
adjust the carrier frequency according to carrier frequency (F23.00).
Cable length

Below 5kHz
Below 2kHz
The controller should be derated if motor cables are too long or their CSA is too large. The current
should be decreased by 5% when per level of CSA is increased. If the CSA increase, so do the current to
ground and capacitance.
Control Cable
To reduce the interference and attenuation of control signal, length of control cable should limit within
50m.
The control cable must be shielded cable. The analogue signal cable must be shielded twisted pair.
Shielded / armoured cable: High frequency low impedance shielded cable should be used.
For example: Copper net, aluminum net or iron net.
