Tachometer Feedback Board Replacement 3
Preliminary Steps Before replacing the tachometer feedback board, shut off the
drive power, wait five minutes for the voltage to discharge, open
the drive door; and remove any Lexan™ shielding as necessary.
Removing the Tachometer
Feedback Board 1. Using a voltmeter, test the voltage across the three phases,
then across the board terminals.
2. Observe the wiring and tag wires as necessary.
3. Disconnect the tachometer leads (terminals 1, 2, and 3).
4. Disconnect the adapter board leads (terminals 5 and 6).
5. Disconnect the wire to TE (terminal 4).
6. Snap the board out.
Installing The Tachometer
Feedback Board Information for grounding, wiring, and scaling a tachometer is
given in the installation section of publication 1395-5.40, Bulletin
1395 Digital DC Drive–User Manual.

ATTENTION: If there is any voltage present,
remove the source of the voltage and check for
voltages again before proceeding to the next step.
