4.2 Control Mode Selection
The E310 Series inverter has two control modes：
1. V/F Control Mode. 2. General Vector Control Mode.
The user can choose these modes with the digital keypad according to the application requirement.
The factory setting is V/F Control Mode. Before operation, please set the control mode and the
related motor parameters in accordance with the following flow chart. (The Vector control mode is
suitable for the motors with the same power rating as the inverter, or one size bigger or smaller if
necessary).
※Note：
1. Use V/F Control Mode：
(1) Use one inverter to drive several motors simultaneously
(2) Motor’s nameplate is unknown or motor’s specifications are too special, it will
cause Auto-tuning fault.
(3) Specification of inverter and motor differs by more than 1 size.
2. One inverter drives several motors (Only in V/F mode), set the motor parameters according to the
following rules：
(1). Sum the rated current of all motors for total inverter current.
(2). Input correct VF Pattern parameter (05-04~05-09).
3. When the nameplate of the motor is unknown, the inverter will be set by default to parameters
according to the standard TECO motor.
4. When parameter 00-00=0, the keypad will display ‘Err2’ when performing Auto tuning.
5. In VECTOR MODE, the max. & min. value of 06-01~06-05 will be limited by one size higher or
lower than TECO standard motor specification. In VF MODE control, there is no limitation.
