10.3 FREQUENCY REFERENCES (CONTROL PANEL: MENU PAR -> P3)
3.3 I/O REFERENCE
Defines the selected frequency reference source when the drive is controlled
from the I/O terminal.
0 = Preset speed 0 - 7
1 = Keypad reference
2 = Reference from Fieldbus (FBSpeedReference)
3 = AI1 reference (terminals 2 and 3, e.g. potentiometer)
4 = AI2 reference (terminal 4 and 5, e.g. transducer)
3.4 - 3.11 PRESET SPEEDS 0 - 7
These parameters can be used to determine frequency references that are ap-
plied when appropriate combinations of digital inputs are activated. Preset
speeds can be activated from digital inputs despite of the active control place.
Parameter values are automatically limited between the minimum and maxi-
mum frequencies. (par. 3.1, 3.2).
10.4 RAMPS & BRAKES SETUP (CONTROL PANEL: MENU PAR -> P4)
4.1 RAMP SHAPE
The start and end of the acceleration and deceleration ramp can be smoothed
with this parameter. Setting value 0 gives a linear ramp shape which causes
acceleration and deceleration to act immediately to the changes in the refer-
ence signal.
