What this Option Provides

The AC Tachometer Interface Card is designed for use with the

following Reliance tachometers RE-045F, RE-045R or RE-050. The

card provides feedback signals for non-regenerative 1397 drives and

cannot be used in conjunction with the Pulse Encoder Interface Card.

Where this Option is Used

This option may only be used with 1397 Non-Regenerative Drives.

Allen-Bradley 1397 AC Tachometer Interface Card How to Select an AC Tachometer Before installing the AC Tachometer Interface Card, the tachometer’s maximum AC output voltage and the card’s maximum DC output voltage must be calculated. Performing these calculations will assure: • That the correct AC tachometer is selected. • That the correct drive Regulator Board settings are made. • That the Tachometer Interface Card is wired correctly.

Allen-Bradley 1397 AC Tachometer Interface Card AC Tachometer Parameter Settings To finish configuring the card for the selected AC Tachometer, up to (4) parameters must be set depending upon the application. When setting AC tachometer parameters, P.194 [Anlg Tach Fdbk] may be used to “zero” the tachometer as indicated. ! ATTENTION: The incorrect setting of parameters P.039, P.047, P.057 and P.058 can cause an overspeed condition.
