Chap. 9 FUNCTION CODES
• Changing the PID command
When UP/DOWN control is selected as a PID command, turning the terminal command UP
or DOWN ON with a run command being ON causes the PID command to change within the
range from 0 to 100%.
The PID command can be specified in mnemonic physical quantities (such as temperature or
pressure) with the PID display coefficients (E40, E41).
UP DOWN
Data = 17 Data = 18
Function
OFF OFF Retain PID command value.
ON OFF
Increase PID command value at a rate between 0.1%/0.1 s
and 1%/0.1 s.
OFF ON
Decrease PID command value at a rate between 0.1%/0.1 s
and 1%/0.1 s.
ON ON Retain PID command value.
Selecting the PID control for process control (J01 = 1 or 2) validates the H61 data as well as
frequency commands.
To validate UP and DOWN terminal commands, it is necessary to select the PID
control (Remote command SV) (J02 = 3).
Enable data change with keypad -- WE-KP
(Function code data = 19)
Turning this terminal command OFF protects function code data from accidentally getting
changed with the keypad.
Only when the WE-KP is ON, you can change function code data with the keypad according
to the setting of function code F00 as listed below.
WE-KP F00 Function
OFF -- Disable changing of all function code data
0 or 2 Enable changing of all function code data
ON
1 or 3 Disable changing of all function code data except F00 data
If no WE-KP terminal command is assigned, the inverter interprets WE-KP as being ON by
default.
• If you mistakenly assign a WE-KP to any digital input terminal, you can no
longer edit or modify function code data. In such a case, temporarily turn this
WE-KP-assigned terminal ON and reassign the WE-KP terminal command to a
correct command.
• WE-KP is only a signal that allows you to change function code data, so it does
not protect the frequency settings or PID command specified by the
and
keys.
