Quick Installation Guide
•
Check all your requirements such as:
– operating mode (unwind brake, unwind drive, winding drive, line drive)?
– characteristics of the brake or drive (signal level, max. current, etc.)?
– configuration of the force sensor (power supply, 4 wire or 6 wire circuit)?
– operating mode of the additional analog input (external reference, etc.)?
– controller output configuration (signal level)?
– feedback output configuration (signal level)?
– digital input / output assignment?
– linking by interface etc.?
– emergency stop procedures?
•
Draw your final wiring diagram according to the wiring diagram (refer to „8.2
Wiring diagram“). Don’t forget the digital input „Controller enabled“
•
Install and wire all your components (refer to „8. Installation and wiring“)
•
Electronic unit: Parametrize and calibrate the measuring amplifier for each channel
(refer to „9. General Operation“)
•
Proceed a test run with low speed and low material tension:
– Input reference value (ref. to „9.5 Inputting the reference value“)
– Enable controller (ref. to „9.8 Automatic operation“)
– Determine PID control parameters and set machine into operation (ref. to
„9.6 Determination of the control parameters“)
•
If required, setup pilot control or line speed overlay (ref. to „10.3 Setup of pilot
control“ or „13.2 Setup of line speed overlay“)
•
If required, do additional settings (refer to „9.9 Additional settings“
Note
It may be that the PID control parameters determined during the test run are no longer
suitable for stable operation after setup of pilot control or increasing of material
tension. Therefore it is useful to adjust the control parameters until the machine runs
stable at the required reference values.
Note
Starting and stopping of the machine takes increased requirements to any control loop.
For stable operating also in these phases, you have to pay special attention to the
starting and stopping behaviour of the whole machine. It is not enough to get stable
operating during normal operating conditions.
