input
0: 0 to 10 VDC; 3: 0 to 20mA

P2-31
Analog Input 1 Scaling
100 %
Defines scaling of analog input 1 at maximum analog input value towards
maximum speed in P1-01.
Output frequency= (Analog input value)/100 * (P2-31)/100 * P1-01 [Hz]
P2-32
Analog Input 1 Offset
0 %
P2-32 defines an offset in % of full range for analog input 1.
A positive offset is deducted from the incoming analog signal and a negative
offset is added.
Example, if P2-30=0–10V and P2-32=10.0%, then 1 volt (10% of 10V) will be
deducted from incoming analog reference prior to it being applied.
5.2 Digital start signal in 2 directions and 8 fixed Preset speeds
Start in two directions and up to 8 fixed speeds. If only 4 fixed speeds are to be used, AIN2 terminal
10, can be excluded. If only 2 fixed speeds are to be used, AIN1 terminal 6, can be excluded.
Table below shows what parameters needs to be set to get 2,4 or 8 fixed speeds.
