Chapter 5 Function Code
[3] PID command with UP/DOWN control (J02 = 3)
When UP/DOWN control is selected as a PID control command, turning the terminal command
UP or DOWN
ON causes the PID control command to change within the range from 0 to 100%.
By using the PID display coefficients, setting is possible with the physical quantities units.
To set UP/DOWN control as a PID command, the
UP and DOWN should be assigned to the digital input
terminals. (
Function code E01 to E09, data = 17, 18)
Table 5.4-153
UP DOWN
Data = 17 Data = 18
Enable
OFF OFF
Retain command value of current PID control.
ON OFF
Increase PID control command value at a rate between 0.1%/0.1 s
and 1%/0.1 s.
OFF ON
Decrease PID control command value at a rate between 0.1%/0.1
s and 1%/0.1 s.
ON ON
Retain current PID speed command 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).
[4] PID command via communication (J02 = 4)
Function code (S13) for communication: send data 20000 d/100% PID command For details of the
communications format, see the RS-485 Communication User's Manual.
- Other than the remote command selection by J02, the multi-frequency 4, 8 or 12 (specified by
C08, C12 or C16, respectively) specified by terminal commands
SS4 and SS8 can also be
selected as a preset value for the PID command.
Calculate the setting data of the PID command using the following expression.

- In dancer control (J01 = 3), the setting from the keypad interlocks with the function code J57 PID
control (dancer basic position) and saved as the function code data.
