F4: Analog Monitor Option

F4 parameters set drive operation when you use analog monitor option card AO-A3. The AO-A3 card has 2 output terminals (terminals V1 and V2) for signals with an Output resolution of 11 bits (1/2048) + encoding and that have an output voltage range of -10 V to +10 V. Install the AO-A3 card to a drive to output analog signals that monitor the output status of the drive (output frequency and output current).

Refer to the AO-A3 card manual for more information about how to install, wire, and set the AO-A3 card.

Use the U monitor number to set the monitor data to be output from terminals V1 and V2 on the AO-A3 card. Enter the last three digits of Ux-xx as the setting value.

  • Use Gain and Bias to Adjust the Output Signal Level of Terminal V1

You must stop the drive to adjust the output signal. Use this procedure to calibrate the drive:

  1. View the F4-02 [Terminal V1 Gain] value on the keypad.

    Terminal V1 will output a voltage = 100% of the monitor set in F4-01 [Terminal V1 Function Selection].

  2. View the monitor connected to terminal V1 and adjust F4-02.

  3. View the F4-05 [Terminal V1 Bias] value on the keypad.

    Terminal V1 will output an analog signal = 100% of the parameter set in F4-01.

  4. View the monitor connected to terminal V1 and adjust F4-05.

  • Use Gain and Bias to Adjust the Output Signal Level of Terminal V2

You must stop the drive to adjust the output signal. Use this procedure to calibrate the drive:

  1. View the F4-04 [Terminal V2 Gain] value on the keypad.

    Terminal V2 will output a voltage = 100% of the monitor set in F4-03 [Terminal V2 Function Selection].

  2. View the monitor connected to terminal V2 and adjust F4-04.

  3. View the F4-06 [Terminal V2 Bias] value on the keypad.

    The analog signal equal to 0% of the parameter being set in F4-03 will be output from terminal V2.

  4. View the monitor connected to terminal V2 and adjust F4-06.
