Tuning procedure:
- Reset the curve flux/current via the Reset flux / if command (FLUX REGULATION \ Flux / if curve menu )
- Set the Motor nom flux
:
Motor nom flux parameter (FLUX REGULATION menu)
- Set the output voltage via the Max out voltage parameter (CONFIGURATION menu) and the correspondent
percentage (100%) in the Out vlt level parameter (FLUX REGULATION menu)
- Set the Flux regulator Flux reg mode = Constant current (FLUX REGULATION menu)
- Set the flux percentage at 100% via the Flux current max parameter (FLUX REGULATION menu)
- Operate the Drive speed, so that the Armature voltage (MONITOR\Measurements menu) corresponds to
the value previously set in Max out voltage (CONFIGURATION menu).
- Via the Flux current max parameter decrease the voltage displayed in Armature voltage, up to obtain an
output voltage equal to the 90% of Max out voltage.
Carry out the reading of the current in the Flux current parameter (FLUX REGULATION menu) and insert
it in the I field cnst 90 parameter (FLUX REGULATION\Flux if curve menu).
- Via the Flux current max parameters decrease the voltage displayed in Armature voltage, to obtain an
output voltage equal to the 70% of Max out voltage.
Carry out the reading of the current circulating in the Flux current parameter (FLUX REGULATION menu)
and insert it in the I field cnst 70 parameter (FLUX REGULATION\Flux if curve menu).
- Via the Flux current max parameters decrease the voltage displayed in Armature voltage, to obtain an
output voltage equal to the 40% of Max out voltage.
