V1.1 1.2 Precautions for use When using the RI9000 series inverter, please pay attention to the following points ： 1.2.1 Constant torque and low speed operation When the inverter is running with a normal motor for a long period of low speed, the heat dissipation effect will be deteriorated, which will affect the life of the motor. If you need low-speed constant torque for long-term operation, you must use a dedicated inverter motor. 1.2.2 Confirmation of motor insulation When applying the RI9000 series inverter, please confirm the insulation of the motor before using the motor to prevent damage to the equipment.
In addition, please check the insulation of the motor regularly when the environment of the motor is bad, to ensure the safe operation of the system. 1.2.3 Negative torque load For situations such as lifting the load, there is often a negative torque, and the inverter will trip if an over-current or over-voltage fault occurs. In this case, the optional braking resistor should be considered. 8 The use phase Safety class Precaution Maintenance Danger Maintenance and inspection can only be performed by professionals. Risk of personal injury. Maintain and inspect devices after power is off. Risk of electric hazard.
Repair or maintain the AC drive only ten minutes after the AC drive is powered off. This allows for the residual voltage in the 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.
