Incremental Operation: For each activation of the Up Contact, the drive output frequency will
increase incrementally, equal to the frequency set by Function 7.15 (factory set to 1.00 Hz). For
each activation of the Down Contact, the drive output frequency will decrease incrementally,
equal to the frequency set by Function 7.15 (factory set to 1.00 Hz).
Note: In Incremental Operation, if the Up or Down Contact is maintained for longer than
2 seconds, the drive output frequency will "free run" up or down in increments set by Function
7.15, for the duration of the contact closure. The rate of change is equal to the Accel/Decel
settings in Function Nos. 3.03 and 3.04. When the contact is opened, the drive output frequency
will stop changing.
Unidirectional Up/Down Frequency Control
Connect the Start/Stop Contact to TB1 Terminal "9", which is factory set for N.O. Start ("0010").
The common of the contacts can be connected to either common TB1 Terminal "4" or "11".
Note: Use a maintained contact for Start/Stop. If a Start/Stop Contact is not used, a jumper
must be installed between TB1 Terminals "5" and "8".
