Cable
Transmitting electrical signals.
Circuit
breaker
Purpose: disconnect power supply and protect the
equipments in case of abnormal overcorrect occurs
Type selection: breaking current of circuit breaker is
defined to be 1.5
~
2 times the rated current of the
drive Breaking time characteristic of circuit breaker
should be selected based on
overload protection time characteristic of the drive
Input chokes
Improve power factor Reduce the impact of
imbalanced three-phase input AC power supply on
the system Suppress higher harmonics and reduce
the conducted and radiated interference to peripheral
devices Restrict the impact of impulse current on
rectifier bridges
Input filter
Reduce conducted interference from power supply to
the drive, improve the immunity of the drive from noise
Reduce conducted and radiated interference of the
drive to peripheral device
Braking
resistor
Purpose: consume motor feedback energy to attain
quick brake
Output filter
Output filter and radiated interference of the drive to
peripheral devices
Output AC
reactor
Avoid the motor insulation damage result from
harmonic voltage Reduce frequent protection from the
drive caused by leakage current In case the cable
connecting drive and motor is over 100 meters, output
AC reactor recommended
