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.

UP
Remote Control
UP Function
ON
Accelerates (increases output frequency) motor
from current frequency
OFF
Output to motor operates normally
28
DWN
Remote Control
DOWN Function
ON
Decelerates (decreases output frequency) motor
from current frequency
OFF
Output to motor operates normally
Valid for inputs:
C_01, C_02, C_03, C_04,
C_05
Required settings:
A_01 = 02
Notes:
•
This feature is available only when the frequency
command source is programmed for operator
control. Confirm A_01 is set to 02.
•
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.
