P-41
PID1 Kp
0.1
30
PI(D) controller proportional gain
Higher values will result in a larger change at the
frequency inverter output frequency as a response
to small changes in the feedback. Too high value
can cause instability
1
P-42
PID1 Ti
0.0 s
30.0 s
PI(D) controller integral time constant
Higher values will result in a more damped
response. Used in systems in which the overall
process responds slowly.
1.0 s
P-43
PID1 Mode
0
1
PI(D) controller 1 mode
0: direct mode. This setting is used when an
increase of the feedback signal should lead to a
decrease of the motor speed.
1: inverse mode. If an increasing feedback signal
should increase the speed of the motor, use
inverse mode.
0
P-44
PID1 Set Point 1 Source
0
1
Defines the set point source 1 of controller 1
0: digital set point signal, set with P-45
1: analog input 1
0
P-45
PID1 Set Point Digital
0.00 %
100.00 %
Digital set point controller 1
Digital set point of the PI controller in case P-44 = 0
0.00 %
P-46
PID 1 Feedback 1 Source
0
5
Defines the feedback source 1 of controller 1
0: analog input 2 (AI2)
1: analog input 1 (AI1)
2: motor current
3: DC-link voltage
4: difference AI1 - AI2
5: max value of AI1 and AI2
0
P-47
AI2 Signal Range
0
6
Configures the Analog input 2 for the selected
signal source type.
0: 0 - 10 V
1: 0 - 20 mA
2: t 4 - 20 mA (Trips in case of wire break)
3: r 4 - 20 mA (Ramps to f-fix1 (P-20) in case of wire
break)
4: t 20 - 4 mA (Trips in case of wire break)
5: r 20 - 4 mA (Ramps to f-fix1 (P-20) in case of wire
break)
6: Ptc-th (connection of a thermistor for motor
protection)
0
P-48
t-Standby
0.0 s
25.0 s
Time after which the drive changes to stand by
mode (inverter output disabled) when running at
min speed (f-min)
0: Standby mode disabled
non-zero: enter standby mode after the time
specified in this parameter.
Operation automatically resumes as soon as the
speed set point increases above P-02.
