run and stop repeatedly until the end of self-learning, so do not touch the motor.
Otherwise, there is a risk of injury.
Make sure that the front cover is installed before turning on the power. Do not remove
the cover when the power is on, otherwise there is a risk of electric shock.
Please prepare an emergency stop switch separately (the stop button is only effective
when the function is set).
Please reset the alarm after confirming that the operation signal is cut off, otherwise there
is a risk of injury.
No-load commissioning of the motor must be performed before commissioning of the
motor load.
Do not touch the inverter heat sink, motor or other hot parts while the equipment is still
running or for a period of time after power failure to avoid burns.
Do not start or stop the inverter by repeatedly turning the power on and off, otherwise the
equipment/system may be damaged.
Before running, please make sure that the motor and machinery are within the allowed
use range, otherwise the equipment may be damaged.
When using on lifting equipment, please also configure mechanical holding device.
Please do not modify the parameters of the inverter at will. Most of the factory-set
parameters of the inverter can already meet the operation requirements, as long as some
necessary parameters are set. Modifying the parameters at will may lead to damage of the
machinery and equipment.
1.2.7 Maintenance and inspection
There are high-voltage terminals in the inverter, so please do not touch them at will.
Otherwise, there is a risk of electric shock.
Be sure to install a protective cover when the power is on. Also, when removing the
protective cover, be sure to disconnect the circuit breaker used for wiring, otherwise there
is a risk of electric shock.
After disconnecting the main circuit, wait at least 10 minutes to make sure that the
charging indicator on the front cover is off before performing maintenance and
inspection, otherwise there is a risk of electric shock due to the voltage remaining on the
capacitor.
Except for designated personnel, others are not allowed to repair, inspect, or replace the
components. Remove any metal accessories (watches, rings, etc.) from your body before
operation. During operation, please use tools that have been insulated, otherwise there is
a risk of electric shock.
