Setup of an Unwind Brake Controller
10.1
Configuring the basic parameters
For an unwind brake controller the following parameters must be set according to your
application:
Parameters CMGZ622
Control mode
Unwind brake
(default)
Pilot control
For the time being set to
No
Offset output
Reset to 0%
Current limit
According to the signal level of the brake used
Output configuration
0...10V or according to the brake used
Ramp diameter
Reset to default = 1.0 s
Ramp reference
Reset to default = 1.0 s
Reference source
According to machine configuration (
internal
or
external
)
Scale ref.input 1
(Only if reference potentiometer is used)
Scale ref.input 2
(Only if reference potentiometer is used)
Torque in use
For the time being set to
No
Holding torque
For the time being set to 0.0, or according to your
requirements (refer to „10.2 Inputting the holding torque“)
Note
There is one additional analogue input for external reference, diameter or line speed
signal. You cannot run the controller with external reference and pilot control the
same time. You must decide which signal you want to process with the controller and
then set the parameters
Reference source
and
Pilot control
accordingly.
Now continue with section „9.4 Entering the Reference Value“. If the general setup is
done, add the special features below according to your requirements.
10.2
Inputting the holding torque
The unwind reel can be hold by the brake while the machine is stopped. For that
purpose the holding torque has to be set in parameter
Holding torque
(ref. to „14.
Parametrisation“). This allows avoiding pivoting for example.
If parameter
Torque in use
is set to
No
, the holding torque is output only while the
controller is enabled.
If parameter
Torque in use
is set to
Yes
, the holding torque is output also while the
controller is disabled.
