8-1 Operation and Simple Running
AC10 Inverter
Chapter 8 Operation and Simple Running
This chapter defines and explains the terms and names describing the control, running and
status of the inverter. Please read it carefully as it will ensure correct operation.
8.1 Basic Conception
8.1.1 Control Mode
AC10 inverter has the following control modes: sensorless vector control (F106=0), VVVF
control (F106=2) and vector control 1 (F106=3).
8.1.2 Mode of Torque Compensation
Under VVVF control mode, AC10 IP66 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)
8.1.3 Mode of frequency setting
Please refer to F203~F207 for the method for setting the running frequency of the AC10 IP66
inverter.
8.1.4 Mode of controlling for running command
The channel for inverter to receive control commands (including start, stop and jogging, etc)
contains 3 modes:
1. Keypad (keypad panel);
2. External terminal control;
3. Modbus control;
The modes of control command can be selected through the function codes F200 and F201.
8.1.5 Operating status of inverter
When the inverter is powered on, it will have one of four types of operating status:
Stopped status
Programming status
Running status
Fault alarm status.
They are described in the following:
Stopped status
If the inverter is re-energised (if “auto-startup after being powered on” is not set) or decelerate
the inverter to stop, the inverter is at the stopped 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 a start command.
The running indicator on keypad panel lights up under normal running status.
