P2240[2] Setpoint of PID-MOP
Min: -200.00 Def: 10.00 Max: 200.00
Level 2
Settings:
722.0=Digital input 1 (requires P0701 set to 99, BICO)
722.1=Digital input 2 (requires P0702 set to 99, BICO)
722.2=Digital input 3 (requires P0703 set to 99, BICO)
722.3=Digital input 4 (requires P0704 set to 99, BICO)
722.4=Digital input 5 (requires P0705 set to 99, BICO)
722.5=Digital input 6 (requires P0706 set to 99, BICO)
722.6=Digital input 7 (via analog input 1, requires P0707 set to 99)
722.7=Digital input 8 (via analog input 2, requires P0708 set to 99)
19.D =Keypad UP cursor
Dependency:
To change setpoint:
1. Use UP/DOWN key on BOP or
2. Set P0702/P0703=13/14 (function of digital inputs 2 and 3)
Note:
P2240=100% corresponds to 4000 hex.
r2250 CO: Output setpoint of PID-MOP
Min: - Def: - Max: -
Level 2
Note:
r2250=100% corresponds to 4000 hex.
P2253[2] CI: PID setpoint
Min: 0:0 Def: 0:0 Max: 4000:0
Level 2
Details:
This parameter allows you to select the source of the PID setpoint. Normally, a digital setpoint is selected either using a
fixed PID setpoint or an active setpoint.
Settings:
755= Analog input 1 2224 =Fixed PI setpoint (see P2201 to P2207) 2250 =Active PI setpoint (see P2240)
Index;
P2253[0] : IN000 (AUTO) 1st. Command data set (CDS) P2253[1] : IN001 (HAND) 2nd. Command data set (CDS)
P2254[2] CI: PID trim source
Min: 0:0 Def: 0:0 Max: 4000:0
Level 3
Details:
This parameter allows you to select the source of the PID setpoint. Normally, a digital setpoint is selected either using a
fixed PID setpoint or an active setpoint.
Settings:
755= Analog input 1 2224 =Fixed PI setpoint (see P2201 to P2207) 2250 =Active PI setpoint (see P2240)
Index:
P2254[0] : IN000 (AUTO) 1st. Command data set (CDS) P2254[1] : IN001 (HAND) 2nd. Command data set (CDS)
P2261 PID setpoint filter time constant
Min: 0.00 Def: 0.00 Max: 60.00
Level 3
Note:
0=no smoothing
r2262 CO: Act. PID filtered setpoint
Min: - Def: - Max: -
Level 2
Details:
Displays PID setpoint in [%] after smoothing.
Note:
r2262=100% corresponds to 4000 hex.
P2264[2] CI: PID feedback
Min: 0:0 Def: 755:0 Max: 4000:0
Level 2
Settings:
755= Analog input 1 setpoint 2224 =Fixed PID setpoint 2250 =Output setpoint of PID-MOP
Index:
P2264[0] : IN000 (AUTO) 1st. Command data set (CDS) P2264[1] : IN001 (HAND) 2nd. Command data set (CDS)
Note:
When analog input is selected, offset and gain can be implemented using parameters P0756 to P0760.
P2265 PID feedback filter timeconstant
Min: 0.00 Def: 0.00 Max: 60.00
Level 2
P2267 Max. value for PID feedback
Min: -200.00 Def: 100.00 Max: 200.00
Level 3
Note:
P2267=100% corresponds to 4000 hex.
When PID is enabled (P2200=1) and the signal rises above this value, the inverter will trip with P0222.
P2268 Min. value for PID feedback
Min: -200.00 Def: 0.00 Max: 200.00
Level 3
Note:
P2268=100% corresponds to 4000 hex.
When PID is enabled (P2200=1) and the signal rises above this value, the inverter will trip with P0221.
P2269 Gain applied to PID feedback
Min: 0.00 Def: 100.00 Max: 500.00
Level 3
Note:
Allows you to scale the PID feedback as a percentage value [%].
A gain of 100.0% means that feedback signal has not changed from its default value.
