Operation mode
6.15.7 Pressure control
Operation conditions:
•
control is available with any supported motor type and with any supported feedback, except for sensorless (also
Hall sensor feedback is not recommended).
•
control is available for all operation mode.
•
pressure transducer feedback is only available via analog input for all operation mode.
•
pressure and speed references via analog input or via fieldbus operation.
•
about regulation, pressure/speed/current regulators are available.
•
brake motor management is available.
•
trapezoidal ramps and “S” ramps are available for speed and pressure.
The following image shows an example of I/O setting, then you can set:
•
type and fullscale for pressure reference or feedback, and speed/pressure ramps.
•
speed, current and pressure limit, and overpressure and underpressure alarm threshold.
•
desired I/O configuration and optimal current/speed PID regulators for application.
•
Pressure PID regulator management shown a further exponential (2^) multiplier parameter useful during
the tuning of the pressure loop regulation to appreciate visible variations. Default parameter set is a good
compromise for the most servo press applications.

“6.09 Drive references” pag. 87
:
•
provide pressure transducer feedback in the differential input +/-10V (pins 1-2 of J9).
•
provide pressure reference in the AUX1 differential input +/-10V (pins 3-4 of J9).
•
provide speed reference in the AUX2 differential input +/-10V (pins 5-6 of J9).
2. for fieldbus operation modes:
•
provide pressure transducer feedback in the differential input +/-10V (pins 1-2 of J9).
•
connect J3 connector and see related fieldbus manuals for information about all control topology
parameters.
3. connect the appropriate input and output signals (please see
).
