Instructions
Pow er
supply
Input three-phase AC pow er supply should be in the range as specified in
this manual
Circuit
breaker
Purpose: disconnect pow er supply and protect the equipments in case of
abnormal overcurrent 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
RCD
Purpose: since the drive outputs PWM HF chopping voltage, HF leakage
current is inevitable
Type selection: type B dedicated RCD is recommended
Contactor
For safety's sake, do not frequently close and break the contactor since this
may bring about equipment faults
Do not control the start & stop of the drive directly through sw itch on and off
the contactor since this w ill result in a reduction on the product life
Input AC
reactor or
DC choke
Improve pow er factor
Reduce the impact of imbalanced three-phase input AC pow er 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 pow er supply to the drive, improve the
immunity of the drive from noise
Reduce conducted and radiated interference of the drive to peripheral
devices
Brake unit
and
braking
resistor
Purpose: consume motor feedback energy to attain quick brake
Type selection: Contact GTAKE technical personnel for type selection of
brake unit. Refer to type selection of braking resistor in Table 3-3 Type
Selection of Peripheral Devices.
Output filter
Reduce conducted 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
Motor
Should match the drive
