6-83
•
When the up/down function is being used, the output frequency will be accelerated to the lower limit if a
run command is input.
•
When the up/down function and jog frequency reference are both assigned to multi-function inputs, an
ON jog frequency reference input has the highest priority.
•
Multi-step References 1 through 8 are all disabled when the up/down function has been set.
•
The output frequency held by the up/down function will be stored in memory if d4-01 (the frequen-
cy reference hold function selector) is set to 1.
This output frequency will be retained even after a power interruption, and operation will be re-
started at this frequency the next time that a run command is input. The stored output frequency
will be cleared from memory if the UP or DOWN command is turned ON while the run command is
OFF.
Note Select and set one of the following functions for multi-function input. Do not set more than one of
them, otherwise a setting error (OPE3) will result.

Acceleration/Deceleration Ramp Hold (Setting: A)
S
UP and DOWN Commands (Settings: 10 and 11)
