P1.15 1679 Reverse Enable 1, 2, 3, 4 RW
Enables or disables the reverse motor direction.
P2.1 222 AI1 Mode 1, 2, 3, 4 RW
Selects the analog input mode for AI1 terminals 2 and 3 for current or voltage, also
need to set DIP switches on control board.
P2.2 175 AI1 Signal Range 1, 2, 3, 4 RW
With this parameter you can select the analog input 1 signal range. For selection
“Customized,” see P2.3 and P2.4.
Figure 37. Analog Input AI Scaling
P2.3 176 AI1 Custom Min 1, 2, 3, 4 RW
P2.4 177 AI1 Custom Max 1, 2, 3, 4 RW
These parameters set the analog input signal for any input signal span within
0–100%.
AI1 Custom Min <= AI1 Custom Max.
P2.5 174 AI1 Filter Time 1, 2, 3, 4 RW
When this parameter is given a value greater than 0, the function that filters out
disturbances from the incoming analog signal is activated.
A long filtering time makes the regulation response slower.
