3.3 References
P3.1 MIN FREQUENCY
Minimum frequency reference, for Automatic control. Manual control allows a different mini-
mum.
Note: if motor current limit is reached, actual output frequency might be lower than parame-
ter. If this is not acceptable, stall protection should be activated.
P3.2 M
AX FREQUENCY
Maximum frequency reference, for Automatic and Manual control.
P3.3 AUTO
REFERENCE SELECTION
Defines the source of main frequency reference in Automatic.
0: Preset speed 0
1: Motorpotentiometer
2: non ASi Fieldbus (only without ASi board)
Preset speed 1-8 can be directly activated by ASi outputs or sensors.
P3.4 P
RESET SPEED 0
Basic preset reference
P3.5 P
RESET SPEED 1
P3.6 P
RESET SPEED 2
P3.7 P
RESET SPEED 3
P3.8 PRESET SPEED 4
P3.9 P
RESET SPEED 5

Preset speeds are selected by digital signals defined in P5.3, P5.4 and P5.5 (binary code).
P3.12 M
OTOR POTENTIOMETER MODE
0: step up / down. Frequency reference is changed at any edge of Increase/Decrease signals,
of the quantity defined in P3.13 and P3.14.
