Commutator motor fails on startup

Tech Note: TN0212
Product: AC32
Version: < 2000
Date Added: 2006-09-11

Issue

Because the voltage supplied to the commutator motor was marginal for initial startup, some commutators could fail to move on startup.

Workaround

The motor drive circuit has been redesigned to ensure ~4.0 V supplied to motor. (ECN 6601)
