DIP Switch S4 Settings
DIP switch S4 must be configured to be greater than or equal to the maximum
DC input voltage. Maximum DC Input Voltage = (Tach Volts/1000 rpm) x Par
45 [Max Ref Speed] x 1.1. See Drive Reference and Feedback Scaling on page
for details on programming speed feedback values.

DIP Switch S15 Settings
DIP Switch S15 is configured for the appropriate drive size at the factory. Do not
change the settings unless you are installing a replacement control board.

ATTENTION: The drive can overspeed if DIP switch S4 is set incorrectly or the
tachometer is wired incorrectly. Failure to observe this precaution could result in
damage to, or destruction of, the equipment.
