P2232 Inhibit rev. direct. of PID-MOP
Min: 0 Def: 1 Max: 1
Level 2
Details: Inhibits reverse setpoint selection when PID motor potentiometer is chosen either as a main setpoint of additional
setpoint (using P1000)
Enum: 0=Reserve direction is allowed 1=Reserve direction inhibited
Note: Setting 0 enables a change of motor direction using the motor potentiometer setpoint (increase/decrease
frequency either by using digital inputs or motor potentiometer up/down buttons.
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)

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.
