Chapter 1 Safety Precautions

1.1 Safety precautions

• The environment cannot contain any explosive gas.
• It must be wired by professional wiring staff. Otherwise, it may cause electronic shock.
• Cut off the power supply before wiring. Otherwise, it may cause electronic shock.
• Do not touch any control port, internal boards, and electronic components while the electricity is turned on.
• Otherwise, it may cause electronic shock.
• Please make sure that the product’s ground wiring port is correctly connected according to national electrical safety standards or other related standards.
• Do not touch any internal board or component until 10 minutes after power shutdown. Please do an electricity check before internal board maintenance. Otherwise, it may cause electronic shock.
• It is forbidden to connect AC power to the product’s output port (U, V, W) or other control ports except for Lk, Lb,Lz. Otherwise, it may cause damage to the inverter.
• Since internal IC can be destroyed by electrostatic, please do not touch any PCB, IC, or IGBT components without any protection. Otherwise, it may cause an unknown fault.
• Make sure that any unexpected conductor such as screws, gaskets, etc., is not left inside the inverter during maintenance.
• Otherwise, it may cause damage to the inverter or even fire.
• If an overcurrent happens during starting up, please check the wiring and start up again.
• Do not stop the machine by cutting off power. Power can be cut off after the motor stops.
• Do not leave the inverter in the sunshine. Otherwise, it may cause damage to the inverter.

1.2 Package inspection
A2 series inverter production undergoes a strict qualification test.
Please check the damage caused by the delivery and the type specification during package inspection.

Chapter 8 Operation Examples

8.1 Operation by a panel
Pn 04 = 1(Command from panel) ，Pn 03 = 1(Frequency from potentiometer) 。
Push the button “RUN” on the panel, the inverter starts up and the running indicator is on.
Push the button again, the inverter would stop.
8.2 Operation by an external signal
Pn 04=2 (command from port “FWD/REV”)
Pn 03=3 (frequency from port “5V”)
8.3 Multi-segment speed
Pn 04=2(command from port “FWD/REV”)
Pn 03=7(frequency from multi-segment 0-7)
8.4 Point move by a panel
Command（Pn 04）must come from panel（=1 ）. Frequency（Pn 03）must be
specified by button（=2. After the inverter stops, push the button “←” to the clockwise point move and “→” to the anticlockwise point move.
8.5 Point move by an external signal
Command（Pn 04）must come from port “FWD/REV”（=2 ）. Frequency （Pn 03）must come from an external digital port （=6 ）. After the inverter stops, connect “D0” and “JOG” to “GND” to point move clockwise, and connect “D1” and JOG” to “GND” to point move anticlockwise.

Chapter 10 Maintenance and Repair

Due to environmental influences such as temperature, humidity, dust, and vibration, etc., and aging components, the inverter may fail at some time. So it needs periodic maintenance and repair.
Notice: please check the following items before maintenance and repair. Otherwise, it may cause electronic shock.

• The power source is cut off.
• The indicator on the panel is OFF.
• Maintenance is performed by professionals.

10.1 Daily maintenance and repair
The Inverter must be installed in the standard environment according to this manual. There may be some unexpected situations during runtime. Please do daily maintenance  work according to the following table. Keep a good runtime environment, log daily data and detect fault causes early. It can extend the life of the inverter.
