Parameter
Parameter Possible settings Information
C04375 0.000 s 1000.000 Acceleration/deceleration ramp
function generator
• Initialisation: 0.000 s
• Alternatively, it is possible from li-
brary V02.09.xx.xx to set a separa-
te deceleration time in C04386. In
the Lenze setting, the setting in
C04386 is used as the decelerati-
on time as usual.
C04376 0.00 % 100.00 Gain of the system deviation in the
area of reduced sensitivity
• Initialisation: 0.00 %
C04377 0.00 % 100.00 Area of system deviation with redu-
ced gain/sensitivity
• Initialisation: 0.00 %
C04378 0.0000 214748.3647 Controller gain
• Setting 0.0000 resets the PID con-
troller.
• Initialisation: 1.0000
C04379 0.001 s 1000.000 Controller reset time
• Setting 1000.000 s deactivates
the I component.
• Initialisation: 1.000 s
C04380 0.000 s 1000.000 Controller rate time
• Setting 0.000 s deactivates the D
component.
• Initialisation: 0.000 s
C04381 0.00 % 200.00 Positive output limit value
• Initialisation: 200.00 %
C04382 -200.00 % 0.00 Negative output limit value
• Initialisation: -200.00 %
C04383 0.001 s 60.000 Filter time constant - actual value
• With the setting 0.001 s the filter
is not active.
• Initialisation: 0.001 s
C04384/1...5 0.00 % 200.00 X values of the characteristic func-
tion
• Subcodes 1 ... 5 correspond to the
point values X1 ... X5.
•Initialisation:
X1, X3 ... X5 = 0.00 %
X2 = 100.00 %
C04385/1...5 0.00 % 200.00 Y values of the characteristic func-
tion
• Subcodes 1 ... 5 correspond to the
point values Y1 ... Y5.
•Initialisation:
X1, X2 = 100.00 %
X3 ... X5 = 0.00 %
