Remote Control Up and Down 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. 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 deceler-
ates 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.

Notes:
•
The availability of this feature does not depend on
A_01 (does not exist for DN Series models).
•
This function is not available when [JG] is in use.
•
The range of output frequency is 0 Hz to the value
in A_04 (maximum frequency setting).
•
The Remote Control Up/Down function varies the
inverter speed by directly writing to the F_01
output frequency setting.
