Note: Use a maintained switch or contact for Start/Stop. If a Start/Stop
Switch or Contact is not used, a jumper must be installed between
Terminals "5" and "8".

Free-Running Operation: Close the Start/Stop Switch or Contact to put
the drive into the 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 Start/Stop
Switch or Contact to put the drive into the Stop Mode.

Incremental Operation: Close the Start/Stop Switch or Contact to put the
drive into the 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 Start/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.

*Use a jumper, between Terminals "5" and "8", if a Start/Stop Switch or Contact is not
required.
