Ramp time 2 selection
Contact open: Acceleration / Deceleration time 1 and Ramp S-shape
selected
Contact closed: Acceleration / Deceleration time 2 and Ramp
S-shape2 selected
Set Acceleration / Deceleration time with parameters 4.2 and 4.3 and the
alternative Acceleration / Deceleration time with 4.4 and 4.5.
Set Ramp S-shape with Par. 4.1 and the alternative Ramp S-shape2 with
Par. 4.4
PID setpoint 2
Digital input high activates setpoint 2 (P14.3), when P14.1=0.
Motor preheat active
Digital input high activates the Motor preheat function (if P16.1 = 2) which
feeds DC-Current to the motor in stop state.

AI1 Custom maximum
AI1 filter time
AI2 Custom minimum
AI2 Custom maximum
These parameters set the analogue input signal for any input signal span
from minimum to maximum.
AI2 filter time
This parameter, given a value greater than 0, activates the function that
filters out disturbances from the incoming analogue signal.
Long filtering time makes the regulation response slower.
