4.1.1 UNIDIRECTIONAL (FORWARD) PRESET FREQUENCY OPERATION

See Figures 11 and 12, on page 17, for connections. See Tables 5 and 6,
on pages 17 and 18, for drive programming.


Connect the Preset Frequency Switches or Contacts to Multi-Function
Input Terminals "1" – "3".


For 2-Wire Start/Stop, connect the switch or contact to Multi-Function
Input Terminal "5", as shown in Figure 11, on page 17. Terminal "5" is
factory set for N.O Start ("0010").


For 3-Wire Start/Stop, connect the switches or contacts to Multi-Function
Input Terminals "5" and "6", as shown in Figure 12, on page 17. Terminal
"5" is factory set for N.O. Start ("0010"). Terminal "6" has been arbitrarily
chosen for N.C. Stop ("0011").


The common of the switches or contacts can be connected to any
available common terminal ("8", "12", "14", "16", "18", "20", "22").


Note: Use a maintained switch or contact for 2-Wire Start/Stop and
momentary switches or contacts for 3-Wire Start/Stop. If Start/Stop is not
used, a jumper must be installed between Terminals "5" and "8" and
Function No. 7.04 must be set to "0010" (factory setting).


Application Notes: 1. Closing the Star/Stop Switch or Contact, without
any of the Multi-Function Input Terminals "1" – "3" switches or 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. 2. The drive will operate in the forward direction without assigning a
Multi-Function Input Terminal code "0006" (Forward/Stop Command) or
"0007" (Reverse/Stop Command). Once these codes are assigned to a
Multi-Function Input Terminal, a switch or contact must be used to select
forward or reverse direction.


2-Wire Start/Stop Operation: Close the Start/Stop Switch or Contact to
put the drive into the Run Mode. When a Preset Switch or Contact is
closed, the preset frequency is selected. Open the Start/Stop Switch or
Contact to put the drive into the Stop Mode.


3-Wire Start/Stop Operation: Momentarily close the Start/Stop Switch or
Contact to put the drive into the Run Mode. When a Preset Switch or
Contact is closed, the preset frequency is selected. Momentarily open the
Start/Stop Switch or Contact to put the drive into the Stop Mode.
