P2257 Ramp-up time for PID
setpoint [s]
0.00 -
650.00
1.00 U, T - - Float 2
Sets the ramp-up time for the PID setpoint.
Dependency: P2200 = 1 (PID control is enabled) disable normal ramp-up time (P1120). PID ramp time effective only on
PID setpoint and only active when PID setpoint is changed or when RUN command is given (when PID
setpoint uses this ramp to reach its value from 0 %).
Notice: Setting the ramp-up time too short may cause the inverter to trip, on overcurrent for example.
P2258 Ramp-down time for PID
setpoint [s]
0.00 -
650.00
1.00 U, T - - Float 2
Sets ramp-down time for PID setpoint.
Dependency: P2200 = 1 (PID control is enabled) disables normal ramp-down time (P1121). PID setpoint ramp effective
only on PID setpoint changes. P1121 (ramp-down time) and P1135 (OFF3 ramp-down time) define the
ramp times used after OFF1 and OFF3 respectively.
Notice: Setting the ramp-down time too short can cause the inverter to trip on overvoltage F2 / overcurrent F1.
r2260 CO: PID setpoint after
PID-RFG [%]
- - - - - Float 2
Displays total active PID setpoint after PID-RFG.
Note: r2260 = 100 % corresponds to 4000 hex.
P2261 PID setpoint filter time
constant [s]
0.00 -
60.00
0.00 U, T - - Float 3
Sets a time constant for smoothing the PID setpoint.
Note: P2261 = 0 = no smoothing.
r2262 CO: Filtered PID setpoint
after RFG [%]
- - - - - Float 3
Displays filtered PID setpoint after PID-RFG. r2262 is the result of the value in r2260, filtered with PT1-
Filter and the time constant given in P2261.
Note: r2262 = 100 % corresponds to 4000 hex.
P2263 PID controller type 0 - 1 0 T - - U16 3
Sets the PID controller type.
0 D component on feedback signal
1 D component on error signal
P2264[0...2] CI: PID feedback - 755[0] U, T 4000H CDS U32 /
I16
2
Selects the source of the PID feedback signal.
Note: When analog input is selected, offset and gain can be implemented using P0756 to P0760 (AI scaling).
P2265 PID feedback filter time
constant [s]
0.00 -
60.00
0.00 U, T - - Float 2
Defines time constant for PID feedback filter.
r2266 CO: PID filtered
feedback [%]
- - - - - Float 2
Displays PID feedback signal.
Note: r2266 = 100 % corresponds to 4000 hex.
P2267 Maximum value for PID
feedback [%]
-200.00 -
200.00
100.00 U, T - - Float 3
Sets the upper limit for the value of the feedback signal.
Notice: When PID is enabled (P2200 = 1) and the signal rises above this value, the inverter will trip with F222.
Note: P2267 = 100 % corresponds to 4000 hex.
