capacitor to discharge to a safe value.
Failure to comply will result in personal
injury.
All pluggable components can be ◆
inserted or pulled out only when power has
been turned off.
Set and check the parameters again ◆
after the AC drive is replaced.
General Precautions
1. Constant torque low frequency running
When inverter with induce motor running at long time low speed, the effection of heat
emission will get worse and influence motor using life. If low speed constant torque running
for long time, user have to use Variable frequency motor.
2. Motor insulation test
Perform the insulation test when the motor is used for the first time, or when it is re-used
after being stored for a long time, or in a regular check-up, in order to prevent the poor
insulation of motor windings from damaging the AC drive. The motor must be disconnected
from the AC drive during the insulation test.
3. Hoist load
In Hoist load application, as the inertia exist, inverter will trip as over current or overvoltage
fault. In the case, braking unit and resistor should be connected.
4.
Vibration of mechanical device
