P1.33.7 Preset Freq 7 P1.3 P1.4 Hz 50.0 130
P1.33.8 PresetFreqMode 0 1 0 182
0 = Binary coded
1 = Number of inputs. Preset frequency is
selected according to how many of preset
speed digital inputs are active
P1.33.9 Ext fault close DigIN SlotA.3 405
FALSE = OK
TRUE = External fault
P1.33.10 Ext fault open DigIN Slot0.2 406
FALSE = External fault
TRUE = OK
5.3.4 PID Control application
You can use the PID control application with
processes where you control the process variable (for
example pressure) through control of the speed of the
motor.
In this application, the internal PID controller of the
drive is configured for 1 setpoint and 1 feedback
signal.
It is possible to use 2 control places. Make the
selection of the control place A or B with DI6. When
control place A is active, the start/stop commands are
given by DI1, and the PID controller gives the
frequency reference. When control place B is active,
start/stop commands are given by DI4, and AI1 gives
the frequency reference.
It is possible to configure all the drive outputs freely in
all the applications. There are 1 analogue output
(Output Frequency) and 3 relay outputs (Run, Fault,
Ready) available on the basic I/O board.
M1.34 PID Control
Code Parameter Min Max Unit Default ID Description
P1.34.1 Gain 0.00 1000.00 % 100.00 118
If the value of the parameter is set to 100
% a change of 10 % in the error value
causes the controller output to change
by 10 %.
P1.34.2 Integration Time 0.00 600.00 s 1.00 119
If this parameter is set to 1,00 s a
change of 10 % in the error value causes
the controller output to change by 10.00
%/s.
P1.34.3 Derivation Time 0.00 100.00 s 0.00 132
If this parameter is set to 1,00 s a
change of 10 % in the error value during
1.00 s causes the controller output to
change by 10.00 %.
