(Example) In order to allocate for the range of 0 to 100 % to the range of 1 to 5 V at terminal [12], set as follows.
[ 3 ] PID command with UP/DOWN control (J02 = 3)
When UP/DOWN control is selected as a PID speed command, turning the terminal command “UP” or “DOWN” ON
causes the PID set point value to change within the range from minimum scale to maximum scale.
The PID set point value can be specified in physical quantity units (such as temperature or pressure) with the
maximum scale (J106) and minimum scale (J107).
To select UP/DOWN control as a PID set point value, the “UP” and “DOWN” should be assigned to the digital input
terminals [X1] to [X5]. ( Function codes E01 to E09 data = 17, 18)

OFF
Retain PID set point value.
ON
OFF
Increase PID set point value at a rate between 0.1%/0.1 s and 1%/0.1 s.
OFF
ON
Decrease PID set point value at a rate between 0.1%/0.1 s and 1%/0.1 s.

ON
Retain PID set point value.
The inverter internally holds the PID command value set by UP/DOWN control and applies the held value
at the next restart (including powering ON).
