A2. UP/DOWN FREQUENCY COMMAND

The Multi-Function Input Terminals can be used for remote Up/Down Frequency Control in lieu of the Keypad.
See Table 15, on page 35, for drive programming. See Figure 23, on page 35, for connections.

Connect the Up and Down Switches or Contacts to Multi-Function Input Terminals "6" and "7", which are
factory set for Up and Down Frequency Command ("0003" and "0004"). The common of the switches or
contacts can be connected to any available common terminal ("8", "12", "14", "16", "18", "20", "22").

Application Notes: 1. The Up/down Frequency Command Operation can be programmed for "Free-Running"
or "Incremental" frequency change by setting Up/Down Frequency Control Mode (Function No. 7.14) for "Free
Running" ("0000" (factory setting)) or "Incremental Change" ("0001"). 2. In "Free Running" Mode, the rate of
change of the "Up" control is proportional to the Accel Time (Function No. 3.03) and the rate of change of the
"Down" control is proportional to the Decel Time (Function No. 3.04). 3. In "Incremental Change" Mode, the
step of change of the "Up" or "Down" control is set by Function No. 7.15 (range is 0.01 – 30.00 Hz (factory set
to 1.00 Hz)).

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.
