Cause : Run Command/Frequency Reference Source Selection Error comes when frequency reference is assigned to an option card (b1-01 = 3) and an input option card is not connected to the drive. The Run command is assigned to an option card (b1-02 = 3) and an input option card is not connected to the drive.

1. Reconnect the input option card to the drive.
2. Frequency reference is assigned to the pulse train input (b1-01 = 4) and terminal RP is not set for frequency reference input (H6-01 > 0) Set H6-01 to 0.
3. Although the digital card input is set for BCD special for a 5-digit input (F3-01 = 6), the data length is set for 8-bit or 12-bit (F3-03 = 0, 1). Set F3-03 to 2 to set the input data for 16-bit.
4. The following values have been set while an AI-A3 option card is installed:
   • The source of frequency reference setting is assigned to an option card (b1-01 = 3).
   • The action for the analog card is set for separate terminal input (F2-01 = 0).
   Properly set parameters.
