Functions
The [UP] [DWN] terminal functions can adjust the output frequency for remote control while
the motor is running. The acceleration time and deceleration time used with this function is the
same as for normal operation ACC1 and DEC1 (2ACC1,2DEC1). The input terminals operate
as follows:
the motor is running. The acceleration time and deceleration time used with this function is the
same as for normal operation ACC1 and DEC1 (2ACC1,2DEC1). The input terminals operate
as follows:
• Acceleration - When the [UP] contact is turned ON, the output frequency accelerates from
the current value. When it is turned OFF, the output frequency maintains its current value.
• Deceleration - When the [DWN] contact is turned ON, the output frequency decelerates
from the current value. When it is turned OFF, the output frequency maintains its current
value.

In the graph below, the [UP] and [DWN] terminals activate while the Run command remains
ON. The output frequency responds to the [UP] and [DWN] commands.
ON. The output frequency responds to the [UP] and [DWN] commands.
It is possible for the inverter to retain the frequency set from the [UP] and [DWN] terminals
through a power loss. Parameter C101 enables/disables the memory. If disabled, the inverter
retains the last frequency before an UP/DWN adjustment. Use the [UDC] terminal to clear the
memory and return to the original set output frequency.
