Chapter 4 The Wiring Of Elevator integrated Drive Controller
c) The grounding or shorting of output terminal is prohibited.
d) Do not connect the capacitor and/or surge filter to the output side of elevator integrated
drive controller. Since there is ultra-harmonics at the output of elevator integrated drive controller,
connection of capacitor and /or surge filter at the output side will make the integrated drive
controller overheat or damage.
No connection of capacitor at the output side of integrated drive controller see fig 4.13
Fig4.13 No connection of capacitor at the output side of integrated drive controller
The schematic diagram of no connection of capacitor at the output side of integrated drive
controller
4.5 anti-interference measures.
4.5.1 The specialized noise filter connected at the output side.
In order to suppress the noise created at the output side of integrated drive controller,
specialized noise filter can be connected at the output side of integrated drive controller. please see
fig 4.14 for the wiring of noise filter at the output side of integrated drive controller.
Fig .4.14 the wiring at the output side of integrated drive controller
4.5.2 Main circuit wiring arrangement
In order to suppress the radiated interference created at the output side of integrated drive
controller and improve the anti-interference performance, the wire of main circuit and that of
control circuit should be separated. The wire of main circuit should go through the grounding
metal tube and should be 10cm away from the signal wire. The wiring arrangement of main circuit
is as below fig 4.15
