V Operation and Simple Running

This chapter defines and interprets the terms and names describing the control, running and status of the inverter. Please read it carefully. It will ensure correct operation.

5.1 Basic conception

5.1.1 Control mode

AC10 inverter has three control modes: sensorless vector control (F106=0), VVVF control (F106=2) and vector control 1 (F106=3).

5.1.2 Mode of torque compensation

Under VVVF control mode, AC10 inverter has four kinds of torque compensation modes: Linear compensation (F137=0); Square compensation (F137=1); User-defined multipoint compensation (F137=2);

Auto torque compensation (F137=3)

5.1.3 Mode of frequency setting

Please refer to F203~F207 for the method for setting the running frequency of the AC10 inverter.

5.1.4 Mode of controlling for running command

The channel for inverter to receive control commands (including start, stop and jogging, etc) contains 5 modes: 0. Keypad control; 1. Terminal control; 2. Keypad + terminal control 3. Modbus control; 4. Keypad + terminal +Modbus

The modes of control command can be selected through the function codes F200 and F201.

5.1.5 Operating status of inverter

When the inverter is powered on, it may have four kinds of operating status: stopped status, programming status, running status, and fault alarm status. They are described in the following:

Stopped status

If re-energize the inverter (if “auto-startup after being powered on” is not set) or decelerate the inverter to stop, the inverter is at the stopping status until receiving control command. At this point, the running status indicator on the keypad goes off and the display shows the display status before power down.

Programming status

Through keypad panel, the inverter can be switched to the status that can read or change the function code parameters. Such a status is the programming status.

There are numbers of function parameters in the inverter. By changing these parameters, the user can realize different control modes.

Running status

The inverter at the stopped status or fault-free status will enter running status after having received operation command.

The running indicator on keypad panel lights up under normal running status.

Fault alarm status

The status under which the inverter has a fault and the fault code is displayed.

Fault codes mainly include: OC, OE, OL1, OL2, OH, LU, PF1 and PF0 representing “over current”,

“over voltage”, “inverter overload”, “motor overload”, “overheat”, “input under-voltage”, “input phase loss”, and “output phase loss” respectively.

For trouble shooting, please refer to Appendix I to this manual, “Trouble Shooting”.

5.2 Keypad panel and operation method

Keypad panel (keypad) is a standard part for configuration of AC10 inverter. Through keypad panel, the user may carry out parameter setting, status monitoring and operation control over the inverter. Both keypad panel and display screen are arranged on the keypad controller, which mainly consists of three sections: data display section, status indicating section, and keypad operating section. It is necessary to know the functions and how to use the keypad panel. Please read this manual carefully before operation.

5.2.1 Method of operating the keypad panel

(1) Operation process of setting the parameters through keypad panel

A three-level menu structure is adopted for setting the parameters through keypad panel of inverter, which enables convenient and quick searching and changing of function code parameters.

Three-level menu: Function code group (firstlevel menu) → Function code (second-level menu) → Set value of each function code (third-level menu).

(2) Setting the parameters

Setting the parameters correctly is a precondition to give full inverter performance. The following is the introduction on how to set the parameters through keypad panel.

Operating procedures:

1 Press the “M” key, to enter programming menu.

2 Press the key “O

”, the DGT lamp goes out. Press ▲ and ▼, the function code will change within the function code group. The first number behind F displayed on the panel is 1, in other words, it displays F1××at this moment.

3 Press the key “O” again, the DGT lamp lights up, and the function code will change within the code group. Press ▲ and ▼ to change the function code to F113; press the “E” key to display 50.00; while press ▲ and ▼ to change to the need frequency.

4 Press the “E” key to complete the change.

5.2.2 Switching and displaying of status parameters

Under stopped status or running status, the LED indicators of inverter can display status parameters of the inverter. Actual parameters displayed can be selected and set through function codes F131 and F132.

Through the “M” key, it can switch over repeatedly and display the parameters of stopped status or running status. The followings are the description of operation method of displaying the parameters under stopped status and running status.

(1) Switching of the parameters displayed under stopped status

Under stopped status, inverter has five parameters of stopped status, which can be switched over repeatedly and displayed with the keys “M” and “O”. These parameters are displaying: keypad jogging, target rotary speed, PN voltage, PID feedback value, and temperature. Please refer to the description of function code F132.

(2) Switching of the parameters displayed under running status

Under running status, eight parameters of running status can be switched over repeatedly and displayed with the keys “M”. These parameters are displayed: output rotary speed, output current, output voltage,

PN voltage, PID feedback value, temperature, count value and linear speed. Please refer to the description of function code F131.

5.2.3 Operation process of measuring motor parameters

The user shall input the parameters accurately as indicated on the nameplate of the motor prior to selecting operation mode of vector control and auto torque compensation (F137=3) of VVVF control mode. Inverter will match standard motor stator resistance parameters according to the parameters indicated on the nameplate. To achieve better control performance, the user may start the inverter to measure the motor stator resistance parameters, so as to obtain accurate parameters of the motor controlled.

·35·

AC10

The motor parameters can be tuned through function code F800.

For example: If the parameters indicated on the nameplate of the motor controlled are as follows: numbers of motor poles are 4; rated power is 7.5kW; rated voltage is 400V; rated current is 15.4A; rated frequency is

50.00HZ; and rated rotary speed is 1440rpm, operation process of measuring the parameters shall be done as described in the following:

In accordance with the above motor parameters, set the values of F801 to F805 correctly: set the value of

F801 = 7.5, F802 = 400, F803 = 15.4, F804 = 4 and F805 = 1440 respectively.

2. In order to ensure dynamic control performance of the inverter, set F800=1, i.e. select rotating tuning.

Make sure that the motor is disconnected from the load. Press the “I” key on the keypad, and the inverter will display “TEST”, and it will tune the motor’s parameters of two stages. After that, the motor will accelerate according to the acceleration time set at F114 and maintain for a certain period. The speed of motor will then decelerate to 0 according to the time set at F115. After auto-checking is completed, relevant parameters of the motor will be stored in function codes F806~F809, and F800 will turn to 0 automatically.

3. If it is impossible to disconnect the motor from the load, select F800＝2, i.e. stationary tuning. Press the

“I” key, the inverter will display “TEST”, and it will tune the motor’s parameters of two stages. The motor’s stator resistance, rotor resistance and leakage inductance will be stored in F806-F808 automatically, and F800 will turn to 0 automatically. The user may also calculate and input the motor’s mutual inductance value manually according to actual conditions of the motor.
