[PID REGULATOR] (PId-)
Code Name/Description Setting range Factory settings
PId- [PID REGULATOR]
Note:
This function cannot be used with certain other functions. Follow the instructions in see "APPLICATION FUNCT. FUn-" on page 197 .
PIF
[PID feedback] [No]
(nO)
nO [No] (nO) : Not assigned (function not active). All parameters of this function are inaccessible.
AI1 [AI1] (AI1) : Analog input
AI2 [AI2] (AI2) : Analog input
PG [Encoder] (PG) : Encoder input if encoder card has been inserted
AIU1 [AI virt com] (AIU1) : Virtual input via the communication bus
Note:
If the equipment is switched to forced local mode ( see "COMM. CARD and FORCED LOCAL (LCF-)" on page 310 ), the virtual
input used in the current configuration remains fixed at the last value transmitted.
AIC1 [AI1 communication] [No] (nO)
The parameter is accessible if [PID feedback] (PIF) = [AI virt com] (AIU1) . This parameter can also be activated via the menu
[INPUTS/OUTPUTS] (I-O-) .
nO
[No]
(nO) : Not active
Mdb [Modbus] (Mdb) : Not applicable
CAn [CANopen] (CAn) : Integrated communication interface (POWERLINK)
nEt [Com. Card] (nEt) : Communication card (if present)
PIF1 [Min PID feedback]
1)
100
Value for minimum feedback. Setting range from 0 to [PID max feedback] (PIF2)
2)
.
PIF2 [Max PID feedback]
1)
1000
Value for maximum feedback. Setting range from [PID min feedback] (PIF1) to 32767
2)
.
PIP1 [Min PID reference]
1)
150
Minimum process value. Control range of [PID min feedback] (PIF1) to [max PID reference] (PIP2)
2)
.
PIP2
[Max PID reference]
1)
900
Maximum process value. Control range from [min PID ref] (PIP1) to [PID max feedback] (PIF2)
2)
.
PII
[Act. internal PID ref.] [No]
(nO)
Internal PID regulator reference
nO [No] (nO) : The reference of the PID controller is supplied by Fr1 or Fr1b ; possibly with the summation / subtraction / multiplication functions.
YES [Yes] (YES) : The reference of the PID controller is an internal reference due to the parameter rPI .
rPI [Int. Ref. PID] 150
Internal reference of the PID controller. This parameter can also be activated via the menu [MONITORING] (SUP-) . Setting range from [min PID
ref] (PIP1) to [max Ref. PID feedback] (PIF2)
2)
.
rPG [PID prop. gain] 0.01 to 100 1
Proportional amplifier
rIG [PID integral gain] 0.01 to 100 1
Integral gain
rdG [PID derivative gain] 0 to 100 0
Derivative gain
PrP [PID ramp]
1)
0 to 99.9 s 0 s
Ramp-up/down ramp of the PID, which is set for a range of [min PID ref] (PIP1) to [max PID ref] (PIP2) or vice versa.
PIC [PID correct. reverse] [No] (nO)
nO [No] (nO)
YES [Yes] (YES)
Inverted offset direction (PIC) :
If PIC = nO , with a positive deviation the motor speed increases. Example: Pressure control with a compressor.
If PIC = YES , with a positive deviation the motor speed drops Example: Temperature control using a cooling fan.
