4.2.2 BIDIRECTIONAL UP/DOWN FREQUENCY CONTROL

See Figure 15, on page 22, for connections. See Table 9, on page 22, for
drive programming.

Connect the Start (Jumper) to Multi-Function Input Terminal "5", which is
factory set for N.O. Start ("0010"). Connect the Forward/Stop and
Reverse/Stop Switches or Contacts to any Multi-Function Input Terminals
"1" – "7". Terminals "3" and "4" have been arbitrarily chosen for
Forward/Stop and Reverse Stop. The common of the switches or contacts
can be connected to any available common terminal ("8", "12", "14", "16",
"18", "20", "22").

Free-Running Operation: Close the Forward/Stop or Reverse/Stop Switch
or Contact to put the drive into the Forward or Reverse Run Mode. When
the Up Switch or Contact is closed, the drive output frequency will increase
for the duration of the switch or contact closure. When the Up Switch or
Contact is opened, the drive output frequency will stop increasing. When
the Down Switch or Contact is closed, the drive output frequency will
decrease for the duration of the switch or contact closure. When the Down
Switch or Contact is opened, the drive output frequency will stop
decreasing. Open the Forward/Stop or Reverse/Stop Switch or Contact to
put the drive into the Stop Mode.

Incremental Operation: Close the Forward/Stop or Reverse/Stop Switch
or Contact to put the drive into the Forward or Reverse Run Mode. For
each activation of the Up Switch or Contact, the drive output frequency will
increase incrementally, equal to the frequency set by Function No. 7.15
(factory set to 1.00 Hz). For each activation of the Down Switch or Contact,
the drive output frequency will decrease incrementally, equal to the
frequency set by Function No. 7.15 (factory set to 1.00 Hz). Open the
respective Forward/Stop or Reverse/Stop Switch or Contact to put the drive
into the Stop Mode.

Note: In Incremental Operation, if the Up or Down Switch or Contact is
maintained for longer than 2 seconds, the drive output frequency will "free
run" up or down in increments set by Function No. 7.15, for the duration of
the switch or contact closure. The rate of change is equal to the
Accel/Decel settings in Function Nos. 3.03 and 3.04. When the switch or
contact is opened, the drive output frequency will stop changing.
