VF-FS1 Industrial Inverter - Toshiba

2) Types of PID control interfaces
F-45
E6581381
Process quantity input data (frequency) and feedback input data can be combined as follows for the PID
control of the VF-FS1:
Process quantity input data (frequency setting) Feedback input data
Setting method
Frequency setting mode selection
/
PID control
(1) External analog setting
VIA (DC: 4-20mA / 0-10V)
(2) External analog setting
VIB (DC: 0-10V)
: External analog input
VIA (DC:4-20mA / DC:0-10V)
: External analog input
(3) Panel input setting Internal
preset-speed setting
VIB (DC:0-10V)
(4) RS485 communication
(5) UP/DOWN from external
contact
(6) Internal preset-speed setting - (=0)
Note 1: About the setting of and : Do not select the same terminal that is used feedback
terminal (VIA or VIB).
Note 2: When using VIA terminal, set or respectively to 52 or 53 to put out signals to RY-RC
or FLA-FLB-FLC.
When using VIB terminal, set or respectively to 60 or 61 to put out signals to RY-RC
or FLA-FLB-FLC.
You can also specify a frequency agreement detection range ().

3) Setting PID control
Set "" or "2" in the extended parameter (PID control)
(1) Set parameters (acceleration time), and (deceleration time) to the system fitting values.
(2) To limit the output frequency, set parameters (upper limit frequency) and (lower limit
frequency). If process quantities are set from the operation panel, however, the process quantity setting
range will be limited by the settings of and .
(3) Input terminal function “PID control prohibited” (function No.14) can changing PID control or open-loop
control. Also Input terminal function “PID control integral value clear” (function No.65) can use.
(4) By the set the f380 or Input terminal function “PID forward/reverse switching” (function No.72) , PID
control is reverse. When a reverse-characteristic is selected at the same time with the parameter and
the terminal, it becomes a forward characteristic.
