Digital Controls Make Operating a Breezethe digital keypad/display module comes mounted on the front panel of the Vlt MiCro. this module has two functions: display and control. Display shows the current status of the drive. Control provides the programming interface. As you'll see, running the Vlt MiCro couldn't be easier!

Function/Program Mode

Pressing the "MoDE" key repetitively displays status information such as the reference frequency, output frequency, or output current.

Enter

Pressing the “EntEr” key stores the parameters in memory.

Run

Used to start operation. it has no effect when the drive is controlled by the external control terminals.

Stop/Reset

stops and resets the parameter after faults occur with the drive.

Up/Down

Press the “Up” or “Down” keys momentarily to change parameter settings. these keys may also be used to scroll through different operating values or parameters.

LED Indicators

these indicators light up during rUn, stoP, FWD and rEV operations.

Motor StartPress the run key to start the motor. Adjust desired speed using the Up and Down arrow keys.

Programmingthe Vlt MiCro is programmed by means of the digital keypad. in order to operate in the Quick setup Mode, the Pin Header/Jumpers (located next to the input terminals) should all be set in the up position.

Note: Speed reference is controlled by the Up and Down arrow keys. If a potentiometer is to be used as the speed reference parameter, Parameter 00 will need to be programmed to d01.

Wiringthere are two wiring systems in an AC motor drive: the power wiring and the control circuit. the power wiring terminals are located at the top of the drive. Control Circuit terminals are located at the bottom of drive.

All terminals blocks are covered by a plastic housing, which can be lifted to gain access to the terminals. When no connections are made to the control terminals, the drive can be operated by the digital keypad/display.
