Tachogenerator Feedback
Using tachogenerator feedback improves speed regulation from
approximately 1% of motor base speed to approximately 0.1% of motor
base speed. Use tachogenerators rated from 7 VDC per 1000 RPM to
50 VDC per 1000 RPM. Connect the tachogenerator to terminals T1
and T2 of terminal block TB502. The polarity is positive (+) for T1 and
negative (-) for T2 when the motor is running in the forward direction.
Place SW504 in the TACH position. See Figures 11, 12 and 13 on pages
24, 25 and 26 for tachogenerator connections. The TACH trim pot must
be adjusted prior to operating with tachogenerator feedback. Refer to
the Calibration section for instructions on calibrating the TACH trim pot.
