Cautions in use motor
Different motor has different max allowable running speed. Motor can not run over the max
●
allowable running speed.
While inverter is running at low speed, the motor auto-cool effect is seriously worse. If motor
●
runs at low speed for long time, it will be damaged for overheat. If needed, please use special
motor for inverter.
While constant speed machinery runs at unconstant speed, there maybe sympathetic
●
vibration. Please install vibration-proof rubber under motor rack or use jumping frequency
control function.
While using frequency inverter or working frequency power supply to drive, the torque
●
characteristic are different. Please do confirm the torque characteristic of the equipment
connected.
The rated current of shift gear motor is different from that of standard motor. Please confirm it
●
and choose the right frequency inverter. Moreover, please do switch the pole while the inverter
input current is 0. Otherwise it may bring inverter protection or damage.
The rated current of diving motor is higher than that of standard motor, please confirm it and
●
choose the right inverter.
While the wire between motor and inverter is long, the max torque of the motor will reduce for
●
voltage drop. So please use thick cable while the distance between the motor and the inverter
is long.
Chapter 3 Installation and Wiring
While stall the inverter in the closed cabinet, please build in cooling fan, air-condition or other
cooling equipments to ensure the temperature at the air-in port below 40℃. So that the
inverter can work safely and reliably.
While installing, please use cloth or paper cover the inverter to prevent metal dust, oil, water
and others.And remove it carefully after working.
While operation, please follow the ESD regulations. Otherwise, the inverter may be damaged.
While multi inverters are installed in the same cabinet, enlugh space must be left for cooling
fan.
Inverter can not work over rated range.Otherwise, the inverter may be damaged.
While transporting the inverter, please hold the firm case. If only hold the pre-cover, there is
danger of inverter main body falling, injury or inverter damage.
