Submenu slip compensation
(Only with software D2A-STD)
TAB1
Submenu containing the slip compensation functions.
To enter the submenu press both SHIFT and SELECT simultaneously.
Function s: slip compensation frequency
TAB1
The frequency with wich is enlarged the inverter output frequency when the inverter ra-
ted current is reached (100%).
For a correct behaviour it is absolutely necessary to define the
no-load current with the function zero.
(See also function x)
SUB SLIP
Range: 0...20 Hz
Default: 0 Hz
Function x: frequency threshold for slip compensation
TAB1
The slip compensation is enabled only for frequencies higher then this value.
With higher BOOST values this limit must be increased in order
to avoid an eventually overcompensation produced by a high
current at low speed. This fact could forbit the deceleration to
ward 0Hz or the inversion of the rotation sense.
SUB SLIP
Range: 0...30 Hz
Default: 0.5 Hz
Function zero: no-load current definition
TAB1
No-load current measuring.
The slip compensation is enabled only for currents greater then the no-load current.
Manual tuning by pressing the INC and DEC buttons or automatic measuring when the
motor has no-load condition by pressing the SHIFT and SELECT buttons (the inverter
signals "scan").
The maximum value of 110 corrispond to 85% of the rated inverter current.
SUB SLIP
Range: 0...110
Default: 0
