2) Types of PID control interface
Process value (frequency) and feedback value can be combined as follows for the PID control.
(1) Process value
(2) Feedback value
PID control reference signal selection
f389
PID control feedback signal selection
0:
fmod
/
f207
selected
1: Terminal board VIA
2: Terminal board VIB
3:
fpid
4: RS485 communication
5: UP/DOWN from external logic input
6: CANopen communication
7: Communication option
8: Terminal board VIC
9, 10: -
11: Pulse train input
0: Disabled
1: VIA
2: VIB
3: VIC
4 to 6: -
Note 1: About the setting of
f389
: Do not select the same terminal that is used feedback terminal.
Note 2: When
f389
is selected to 3, process value is set to
fpid
.
Be careful it is not value of
fc
setting. In case value that is set by setting dial is saved on
fpid
.
Note 3: To make the inverter send out a signal that indicates whether the value of feedback agree with (or reaches)
the value of processing, assign the output terminal function 144 or 145 to an unassigned output terminal.
You can also specify a frequency agreement detection range (
f167
). (Refer to 6.3.4)
3) Setting PID control
Set "
" (Process type PID control operation) in the parameter
f360
(PID control)
.
(1) Set parameters
acc
(acceleration time), and
dec
(deceleration time) to the system fitting values.
(2) Please set the following parameters to place limits to the setting value and the control value.
Placing a limit to the process value : The parameter
f367
(Process upper limit),
f368
(Process lower limit)
Placing a limit to the output frequency : The parameter
ul
(Upper limit frequency ),
ll
(Lower limit frequency )
Note 4: Assigning the PID control prohibition (input terminal function number: 36,37) to any logic input terminal, PID
control function is stopped during the terminal ON.
