Derivative D1 / D2 / D3 / D4
Applies to:
Unwind drive
Winding drive
Line drive
Use:
The D value determines the behaviour of the „D“ component of the
controller.
This parameter can be changed while the controller is enabled. The
new value is taken for the control loop when quit parameter mode.
There are 4 different P values available (P1...P4). The BCD digital
inputs are used for switching (ref. to „9.7 Switching the control
parameters“).
Range:
0.001 to
10.000
Default:
0.010
Increment:
0.001
Unit:

Error limit
Applies to:
Unwind brake
Unwind drive
Winding drive
Line drive
Use:
This parameter allows to hold the feedback value fed to the
controller within a defined range. Feedback values exceeding this
range are limited to the range. Thus extreme peaks of the control
output value are avoided in case of high variations of the tension
feedback value (i.e. with rough running reels). This allows to set the
PID parameters more sensitive even in case of poor machine
conditions. The feedback value in the display is not modified with
this parameter.
The percentage refers to the tension reference value. For example a
setting of
80%
with a reference value of 100N limits the feedback
value to ±80N max.
If the parameter is set to
100%
the function is disabled.
Range:
1.0
to
100.0
Default:

Unit:

Alarm control error
Applies to:
Unwind brake
Unwind drive
Winding drive
Line drive
Use:
The digital output „Alarm control error“ and the LED „Alarm
control error“ will be activated if the control error exceeds the
tolerance set in this parameter.
Range:
0.1
to
100.0
Default:
10.0
