Specification of high-performance vector convertor
1.1.6 During operation:
Danger
●
Do not touch cooling fan or discharge resistance to feel temperature, otherwise burn may occur!
●
Non-professional artisan shall not detect signal, otherwise personal injury or device damage may occur
Caution
●
Avoid things falling in device during operation of frequency convertor, otherwise damage may occur!
●
Do not control driver by turning on or off contactor, otherwise damage may occur!
1.1.7 During maintenance:
Danger
●
Do not repair or maintain device when electrifying, otherwise electric shock may occur!
●
Only maintain and repair driver when voltage of frequency convertor<DC36Vsince 2 minutes after
outage, otherwise residual electric charge on capacitance may cause personal injury!
●
Those without professional training shall not repair or maintain frequency convertor, otherwise persona
injury or device damage may occur!
●
Parameters shall be set after changing frequency convertor, all pluggable plugins shall be inserted and
plugged after outage!
1.2 Precautions
1.2.1 Insulation inspection of motor
When firstly using motor, using motor again after putting for a long time and regularly checking
motor, insulation inspection of motor is essential to prevent damaging frequency convertor due to invalid
insulation of motor winding. During insulation inspection, separate motor wire from frequency convertor.
500V voltage-type tramegger is suggested and ensure measured insulation resistance≥5MΩ.
1.2.2 Thermal protection of motor
If selected motor does not match with rated capacity of frequency convertor, especially if rated
power is larger than that of frequency convertor, please adjust related parameter values of motor
protection or install thermal relay in front of motor for protection.
1.2.3 Operation above power frequency
The frequency convertor offers output frequency at 0Hz～3200Hz. If users need to operate at above
50Hz, please consider the tolerance of mechanical device.
1.2.4 Vibration of mechanical device
Mechanical resonance point of load device may exist at certain output frequency of frequency
convertor, and hopping frequency parameter can be set to avoid.
1.2.5 About heating and noise of motor
Output voltage of frequency convertor is PWM wave containing certain harmonic, so temperature
rise, noise and vibration of motor will slightly increase when comparing with power frequency operation.
