Analog inputs
Description:
AI1’ = -2 V, means the motor will spin in the opposite direction with a reference in module equal to
2 V.
The internal values AI1’, AI3’, AI4’ and AI5’ are the result of the following equation:
AIx’
= (
AIx
+

10 V
)

Gain
Example:
AI1 = 5 V, OFFSET = -70 % and Gain = 1,00

1 = -2 V
AI1’ = -2 V, means the motor will spin in the opposite direction with a reference in module equal to 2 V.

Description:
When current signals are used at AI1 input, put S2.A on the MVC4 control card in the “ON” position.
For options 2 and 3 inverse reference is attained, that is, maximum speed is obtained with minimum reference.
