10 - PID Parameters
Code Parameter Name / Range
10-00 PID target value source setting
1: AI1 given
2: AI2 given
3: Pulse given
4: Use 10-02 setting
5: Reserved
6: Frequency Command (00-05)
Note: Parameter only active when frequency command selection (00-05) is set to 5.
When 10-00=1 or 2, source of signal is proportional to be corresponding to PID target via analog input termi-
nal.
Forexample:
0~10V is corresponding to 0~100% target value. When being given 2V, 20% target value is obtained.
When 10-00=3, PID target value is pulse input. The proportion of pulse input is set depending on the parame-
ters of 03-30 (pulse input scales) ~ 03-34 (pulse input lter time).
For general purpose of PID setting, set 10-00=4 to set the PID target value.
When 10-00=4, 10-02 (PID target value) is set at percentage and PID setting is at main screen monitor (12-
38).
Maximum target value is set by parameter 10-33 (PID feedback maximum value), the decimals is determined
by parameter10-34 (PID decimal width), and the unit is set by parameter 10-35 (PID unit).
Forexample:
Set 10-33 = 999, 10-34 = 1, 10-35 = 3, and set 10-02 to 10%
Then 9.9PSI is displayed at the main screen monitor (12-38) and can be modied at this monitor. Maximum
value is 99.9 PSI (limited to the setting value of parameter 10-33).
When 10-00=6, the current frequency command is proportional to be corresponding to PID target.
Code Parameter Name / Range
10-01 PID feedback value source setting
1: AI1 given
2: AI2 given
3: Reserved
Note: Parameter 10-00 and 10-01 cannot be set to the same source. If both parameters are set to the same source the
keypad will show a SE05 alarm.
Code Parameter Name / Range
10-02 PID target value
0.00~100.00 %
10-03 PID control mode
xxx0b: PID disable
xxx1b: PID enable
xx0xb: PID positive characteristic
xx1xb: PID negative characteristic
x0xxb: PID error value of D control
x1xxb: PID feedback value of D control
0xxxb: PID output
1xxxb: PID output + Frequency Command
PID target value source setting (10-00/) PID feedback value source setting (10-01).
