A2 Inverter (0.75-30kW) Pn 01 Chapter 7 Description of Configure Parameters Default display content：1——30000 RUN： 1 means it will display runtime frequency Otherwise, it displays motor’s synchronization speed. 2——30000 is motor synchronization speed STOP：it will display frequency given by external signal. Pn 02 Initial startup frequency by panel or other method Range：000.01Hz－400.00Hz，the initial panel data and external signal frequency during startup.
A2 Inverter (0.75-30kW) Pn 09 Deceleration time with range：000.01S－650.00S Decelerate time (from Pn10 to 0Hz). Pn 10 Maximum runtime frequency with range：000.10Hz－400.00Hz Maximum output frequency by inverter. Pn 11 Minimum runtime frequency with range：000.10Hz－400.00Hz If the frequency from command below this value, inverter will stop. It wouldn’t recover until command frequency up this value. Pn 12 Motor rating frequency with range：010.00Hz－400.00Hz It is used for modify the V/Fcurve.
A2 Inverter (0.75-30kW) Pn 15 Startup DC braking voltage：1V—100V By proper tuning of this parameter, motor can start normally from fully stop state without any difficult caused by motor’s free motion and rotate direction.

A2 Inverter (0.75-30kW) Chapter 10 Maintenance and Repair Due to the 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. 1. Power source is cut off. 2. Indicator on panel is OFF. 3. Maintenance is performed by professionals. 10.
A2 Inverter (0.75-30kW) 10.2 Periodic maintenance The Inverter needs periodic maintenance every 1 or 3 months which depends on the runtime environment. Notice: Machine maintenance or component replacement must be performed by professionals. If any metal objects such screws or washer are left inside the machine, it would cause fatal damage to the inverter！ Check items： 1、 Whether the control port screws are loose or not; 2、 Whether the main loop port i s loose or not.
A2 Inverter (0.75-30kW) ２. filter electrolytic capacitor Cause of damage: high environment temperature, frequently load change, long-time fully load. Criterion: liquid leak, wrong position of safety valve, capacity measurement. 10.4 Store of inverter Precautions for storing inverter: 1. It cannot be stored in high temperature, moist, dusty, metal dust, corrosive gas places. 2. It will speed up the capacitor aging during long-time store. Make sure that turn on inverter once every year.
