8.4.2.4 PRESET FREQUENCY CONTROL
The drive is factory programmed for 7 Preset Frequencies, which can be selected using remote
contacts connected to Multi-Function Input Terminals "1", "2", and "3" (TB1 Terminals "5", "6",
and "7"). See Table 8, for the terminals to select for the preset frequencies.
The 7 Preset Frequencies are obtained using a combination of Multi-Function Input Terminals 1,
2, 1+2, 3, 1+3, 2+3, 1+2+3. The Preset Frequencies can be changed from their factory settings
by reprogramming Function 7.07 – 7.13.
8th Preset Frequency: If none of the Multi-Function Input Terminals are activated, the drive will
operate at the Stored Set Frequency (Function No. 3.00) of 5.00 Hz. If the 8th Preset Frequency
is not required, set Function No. 3.00 to 00.00 Hz.
Note: For Preset Frequency Operation, the drive does not have to be reprogrammed for
External Contact Operation. Multi-Function Input Terminals "1", "2", and "3" (TB1 Terminals "5",
"6", and "7") are factory set to codes "0000", "0001", and "0002".

See Figures 28 and 29, on page 38, for connections and drive programming. The common of
the contacts can be connected to either common TB1 Terminal "4" or "11".
Connect the Preset Frequency Contacts to Multi-Function Input Terminals "1", "2", and "3" (TB1
Terminals "5", "6", and "7"). Use Functions 7.07 – 7.13 to program the desired Preset
Frequencies.
Application Note: Closing the Star/Stop Contact, without any of the Multi-Function Input
Terminals "1", "2", and "3" (TB1 Terminals "5", "6", and "7") contacts activated, will result in the
drive operating at the factory preset frequency of 5.00 Hz. For zero speed operation, reprogram
Function 3.00 to "00.00" Hz.
