operation
Terms related to the control, operation and status of the inverter will be mentioned several times in
the following chapters. Please read this chapter carefully before using the product in order to
properly understand and use the functions mentioned in the subsequent chapters.
Do not turn off the input power until you have confirmed that the inverter shell is installed. Do
not remove the inverter shell after power is applied, otherwise there is a risk of electric shock.
If the inverter has been set up with the power failure restart function, do not approach the
mechanical transmission equipment to prevent injuries as the inverter starts the mechanical
equipment when the power is turned on.
If the energy consumption braking resistor is installed, please do not touch the braking resistor,
otherwise there is a risk of electric shock and burns.
Before the inverter starts the motor and mechanical equipment, please confirm the allowable
range of the motor and mechanical equipment, otherwise there is a risk of injury.
Do not check the measurement signal during the operation of the inverter, otherwise there is a
risk of damage to the equipment.
Do not change the parameter setting of the inverter at will, otherwise the desired operation may
not be achieved and there is a risk of damaging the transmission equipment.
Before switching the operation command channel of the inverter, please make sure to debug
first, otherwise there is a risk of damaging the equipment and personal injury.
5.1 Running command setting
The operator is the basic tool for inverter operation. It can be used to observe various status and error
codes of the inverter, and also set and view various parameters of the inverter. This section describes
the basic operation of the operator.
5.1.1 Inverter operation command channel
It specifies the physical channel for the inverter to receive operation commands: start, stop, etc.
There are three types of operation command channels:
Operation panel: Control with RUN, STOP/RESET, LO/RE keys on the operation panel;
Control terminal: Control with control terminals X0~X6 (digital), A0~A1 (analog);
Communication port: Control start and stop through the upper computer with control terminals A+,
B- (Modbus).
The command channel can be set by function code P10.02.
Note: Before switching the command channel, please make sure to debug first, otherwise there is a
risk of damaging the equipment and personal injury!
5.1.2 Inverter frequency setting channel
There are four physical channels with preset frequencies under normal running mode, which are
respectively:
