1329I-5.5 Integrated Drive/Motor — January, 2000

8.3.7 Reverse Disable (Position 7)

The switch at position 7 enables or disables reverse rotation of the motor. It is factory-set
to enable a forward-to-reverse change of motor direction. If this switch is in the ON
position, the reverse direction is disabled (locked out). In other words, the motor can
run in the forward direction only.

Settings (Position 7):

OFF position = Reverse Enabled (Forward/reverse change allowed; default)
ON position = Reverse Disabled (Reverse direction prohibited)

8.3.8 Minimum Speed Select (Position 8)

The switch at position 8 is used to select whether the minimum speed will be 0 RPM
(0 Hz) or will be determined by the preset inputs (terminals 8, 9, and 10 on the control
terminal block).

Important:

DIP switch position 8 defines whether terminals 8, 9, and 10 are used as
presets (default) or to define the unit’s minimum speed (user option). If
you select the ON position (Minimum Speed from the Control Signal
Terminal Block), you cannot use the speed reference presets. See Section
7.5.1 for information about the preset speed inputs.

Settings (Position 8):

OFF position (Default) = 0 RPM (0 Hz) Minimum Speed
ON position = Minimum Speed from the Control Terminal Block

When the switch in position 8 is ON, the minimum speed will be determined as shown
in the following table:
