DETAILED PARAMETER DESCRIPTION
AI2 has a variation range from -10 V to 10 V no matter if P0239 = 0 or 4, that is, an input voltage of 0 V
corresponds in P0019 = 50 %. If it is necessary that 0 V correspond to P0019 = 0 %, the following setting
must be done:
P0238 = 2
P0240 = -50 %

Description:
When current signals are used at AI2 input, put S2.B on the MVC4 control card in “ON” position.
For options 2 and 3 inverse reference is attained, that is, maximum speed is obtained with minimum reference.
