Only the qualified electrical engineer can perform the wiring, otherwise there will be
danger of electric shock.
A circuit breaker must be installed between the mains and the controller; otherwise
there will be danger of fire.
Wiring can only be done after the mains input are cut off; otherwise there will be
danger of electric shock.
Please connect the controller to the ground according to the st
andard, otherwise there
will be dangerous
Do not connect the input terminals with the output terminals (U, V, W). Please note
the marks and do not connect the wrong wires otherwise the controller may be
damaged!
Ensure the wiring meet the EMC requirements and the local safety standard. The wire
size shall be determined according to the manual, otherwise accidents may occur!
Brake resistor must not be connected between the DC bus termina
ls (+) and (-),
otherwise fire may occur!
Encode connection must use Shielded line, shielding layer must be one side
connected to earth reliably!
Communication wires must use STP with the length of the lay between 20mm and
30mm, shielding layer must be connected to earth!
1.1.4 before Power-on
Please confirm the mains voltage level is consistent with that of the controller ;the
input (R,S,T) and output (U,V,W) wirings are correct; and check if there is any short
circuit in peripheral circuit and if the wiring is fixed and fast; otherwise the controller
may be damaged!
Ensure the synchronous motor has done the dynamic auto-tuning and try to run the
motor before restoring wire ropes.
No p
arts of controller must be through the over-voltage testing since it has been done
in the factory; Otherwise accidents will occur!
Mount the cover plate properly before power-on the controller; otherwise there will be
danger of electric shock!
All the external equipment wirings must be connected according to the instruction of
this manual, or accidents may occur!
