Advanced Operation
PID Control Settings
Parameter Display name p y
number
b5-01 PID Mode
This parameter cannot be changed during operation.
Set value
0 PID disabled
1 PID enabled (Deviation signal is put through derivative control.)
2 PID enabled (Feedback signal is put through derivative control.)
3 PID enabled. (Frequency reference and PID control/deviation signal are put through
derivative control.)
4 PID enabled. (Frequency reference and PID control/feedback signal are put through
derivative control.)
Note 1. To enable PID control, set 1 through 4. (Normally 2 or 4 is used for measured-value derivative
PID control.)
Note 2. If the target speed of the application (e.g., tension control) is rather clear and PID control is
required for fine tuning, set 3 or 4 for frequency reference and PID control.
Setting Target Values for PID Control
The following guidelines can be used to select target values for PID Control.
c
Frequency reference input,
voltage: Terminal 13
Setting via Digital Operator
Option frequency reference
Multi-function analog input:
Terminal 16
Frequency reference, current:
Terminal 14
Note When using different input signals for frequency reference and PID control, set the PID target
value to either a multi-function analog input or the frequency reference (current).
Setting Feedback Values for PID Control
The following guidelines can be used to select feedback values for PID Control.
c
Multi-function analog input:
Terminal 16
Frequency reference, current:
Terminal 14
Note 1. Use the gain and bias settings for the analog inputs to adjust the feedback value.
6-50
Setting g Units Default
range setting
0 to 4 --- 0
The frequency source selected for parameter b1-01 is used as the
target value.
Note 1. If the PID control target value is not set for a multi-function ana-
log input or frequency reference (current) selection (H3-05, log in ut or frequency reference (current) selection (H3-05,
H3-09), then the setting of b1-01 is used automatically.
Note 2. Frequency references 2 to 8 and the inching reference are
enabled regardless of the setting of b1 01 enabled regardless of the setting of b1-01.
Note 3. Operation will be clearer if o1-03 is set to 1 (% unit) when set-
ting from a Digital Operator.
Set C for the function selection of multi-function analog input terminal
16 (H3-05) to select the PID target value.
Set C for the function selection of frequency reference (current)
terminal 14 (H3-09) to select the PID target value.
Set B for the function selection of multi-function analog input terminal
16 (H3-05) to select the PID feedback value.
Set B for the function selection of frequency reference (current)
terminal 14 (H3-09) to select the PID feedback value.
