Example 5: Remote Start/Stop (3-wire) & Speed Changes via the Speed Pot
This configuration is best utilized when a person has control of the inverter and the application. Both potentiometers
should be rated between 2kΩ and 5kΩ of resistance and rated at least 1/4 watt each. The trim pot. is optional, but
without it the manual speed pot. will run the inverter at full speed when the pot is only turned 2/3 of a full turn.
Operation
By momentarily closing push-button (PB1), while push-button (PB2) is closed, the inverter will run
up to the frequency (speed) set into U-01Frequency Ref..
By opening push-button (PB2) at any time, the inverter will stop.
When switch (SW1) is in the open position the motor will run in the forward direction. If the
switch (SW1) is closed, the motor will reverse direction.
The frequency reference (speed) is proportional to the signal level present on terminal FV
0V=0Hz, 5V=30Hz and 10V=60Hz.
When the LOCAL/REMOTE key is pressed, the inverter will act as Example 1.

Note: After the changes are made, the DRIVE, SEQ and STOP LED’s will be lit.
