Use Notice Points - EASY DRIVE ED3000 Series Use Manual

ED3000 系列高性能通用变频器使用说明书
1． Please pay attention to the CMOS IC in the keyboard,
control circuit board and the drive circuit board.
If touch the PCB with the finger directly, the electrostatic
induction may damage the IC circuit board.
2． Do not change wiring and take down the terminal wiring
when power on.
If check the signal when running, may damage the
equipment.

1.3 Use notice points

Using ED3000 series inverter，please notice that：
1、Run with constant torque of low-speed
If need to run for a long time with constant torque of low-speed, must select
motor of frequency conversion for use. Use general asynchronous AC motor when
running at a low speed, should control temperature of the motor or carry on heat
dissipation measure forcedly, so as not to burn the generator.
2、Insulation check to the motor
Should make insulation check to the motor before using it for the first time or
after a long time placement, otherwise inverter may be damaged. Moreover, please
make insulation check to the motor regularly when the environment is tough for the
safety of the system.
3、Negative torque load
For hoist and great inertia load, etc., the inverter would shut off frequently due
to over-current or over-voltage failure, in order to guarantee normal work, should
consider choosing proper brake package.
4、Mechanical resonance of the load
The inverter may meet with mechanical resonance of the load within certain
