Bidirectional Operation with Forward/Reverse
Connect the high side of the Main Speed Potentiometer to TB1 Terminals "2" (+5 Volts), the
wiper to TB1 Terminal "3" (Analog Signal Input), and the low side to TB1 Terminal "4"
(Common). Connect the Start/Stop Contact to TB1 Terminal "9", which is factory set for N.O.
Start ("0010"), and to either TB1 Terminal "4" or "11". Connect the Forward/Stop Contact to TB1
Terminal "7" and to either common TB1 Terminal "4" or "11". Connect the Reverse/Stop Contact
to TB1 Terminal "8" and either common TB1 Terminal "4" or "11". See Figure 25, for
connections, Jumper J2 settings, and drive programming.
Operation: Close the Forward/Stop or Reverse/Stop Contact to put the drive in the Forward
Run Mode or Reverse Run Mode. Rotate the Main Speed Potentiometer clockwise to increase
motor speed and rotate the Main Speed Potentiometer counterclockwise to decrease motor
speed. Open the contact to put the drive in the Stop Mode.

8.4.2.3 UP/DOWN FREQUENCY CONTROL
Up/Down Frequency Control allows the drive output frequency to be increased and decreased
with a remote "Up" contact and "Down" contact. The "Up" contact increases drive output
frequency and the "Down" contact decreases the drive output frequency. See Figure 26, on
page 35, for connections and drive programming.
Free-Running Operation: When the Up Contact is closed, the drive output frequency will
increase for the duration of the contact closure. When the Up Contact is opened, the drive
output frequency will stop increasing. When the Down Contact is closed, the drive output
frequency will decrease for the duration of the contact closure. When the Down Contact is
opened, the drive output frequency will stop decreasing.
