Using Up/ Down Function with Frequency Command Hold (L4-00)

When the Run command is removed and L4-00 =0 (Frequency Command Hold Disabled),
the Up/ Down command will be reset to 0.
· When L4-00=1 (Frequency Command Hold Enabled), the drive will save the frequency
command set by Up/ Down command. When the drive stops, the frequency command will
be saved. To reset the saved command to 0, remove the Run command and close the Up
or Down input. Refer to L4-00 for details.
Using Up/ Down Function with Frequency Command Limits (L2)

The frequency command upper limit is set in L2-00.
· The frequency command lower limit can be set by analog input or L2-01. If the analog
input is set to 2, whichever smaller from the analog input or the L2-01 setting is the lower
limit.
Up/ Down command operation is illustrated in the following figure. In this example, the
frequency command lower limit is determined by L2-01.
