equipm en t and make the equipment work abnormally. Follo wing m ethod can be used:

MO 1

A) If the mea sur ing me ters, radio equipment and sensors and their signal cables are installed in a
cabinet together with the drive, these equip me nt c ables will be eas ily disturbed. Take the actions
below to s olve the problem: The equipment and the signal cables should be as far away from the
inverter as possible; Si gnal cable s and power cabl es shall not be route d in paral lel or boun d together;

inverter's grounding cable .

6 . 1 Influence of Harmonics

1) The h igh frequency harmoni cs of m ains supply will influence the rectifying circuit of t he inverter.
The harmonics will heat t he rectifying circuit and even damage the circuit. So, it is recommended to
install the filt ering device in the envi ronment where the power quality i s poor.

2) Since the in verter output has high frequency harmonics, the output cannot be ins talled with

capacitor or surge s uppressing devices because the cap acitor and s urge suppressing device may
resonate the circuit and damage the equipment.

6.3 Leakage current
The inver ter has two ki nds of leakage curre nt, one is the grounding leakage c urrent and anoth er is the
lea kage current between the lines:
1) Grounding leakage curr ent:
The distributed capacitance exist s between the cables an d the ground, and the bigger the capa citance

6. 2 EMI

1) Two kinds of EM I, one is the EMI around the inverter and distu rbs the inverter. T his kind of E MI is
weak, besides the in verter has been designed with strong immunity. Another i s the E MI from the
inverter that m ay influence the equipment around the inverter. The inve rter its elf is a disturbance
source b ecaus e it outputs PWM wave through high carrier frequency, so solving the EMI issue is
mainly to reduce the EMI of inverter.

The le akage cur rent is increased wit h the incre ase of the circuit curren t, so the l eakage curren t is big if
the motor power is big.
2) Lea kage current between lines:
The distributed capacitance exist s in the inver ter抯 o utput cables, and resonanc e may occur if high
fre quency ha rmonics e xist in the current, thus the lea kage current occurs, which may result in the wrong

M ethods:
A) Inverter an d oth er equipment shall be well grounded and the gr ounding res istance shall be less than

5ohm.
B ) Inverter's power cables shall be vertical instead of parallel with the control cables.
C ) For the app lication with strong dis turbance, the power cables from the motor to the inverter shall b e

The method to solve this issue is to r educe the car rier fre que ncy or install the output reactor. I t is

current wave and low motor noise;
The disadvantages of using high carrier frequency: increased switch loss and inverter temperature rises,

affecting invert er output capacit y so that it should be operated at derating under hi gh carri er frequency
conditions; in the me an time, inverter leakage current and it s electromagnetic interference to external are
i ncreased.
The situations of usi ng l ow carrier frequency is on the contrary. Too low carrier frequency can cause
operation unstable, t orque reduced a nd even oscillation at low frequency.

2: Forbid i nverse operating. Forbidding inverter inverse operation is suitable to specific applicat ion that
inverse operat ing is forbidden.

When inverter is fact ory rele ased, its carrier frequenc y has been set properly. Generally the user does
not need to modify t his parameter.
